Wiki143:Manual of Style

This Manual of Style (MoS or MOS) is the style manual for all English Wikipedia articles.Template:Efn This primary page is supported by further detailed subpages, which may be cross-referenced here and are listed at Wikipedia:Manual of Style/Contents. If any contradiction arises, this page has precedence.Template:Efn

Editors should write articles using straightforward, succinct, and easily understood language. Editors should structure articles with consistent, reader-friendly layouts and formatting (which are detailed in this guide).

Where more than one style or format is acceptable under the MoS, one should be used consistently within an article and should not be changed without good reason. Edit warring over stylistic choices is unacceptable.Template:Efn

New content added to this page should directly address a persistently recurring style issue. Template:TOC limit

Retaining existing styles

Sometimes the MoS provides more than one acceptable style or gives no specific guidance. When either of two styles is acceptable it is generally considered inappropriate for a Wikipedia editor to change from one style to another unless there is some substantial reason for the change.Template:Efn

Edit warring over style, or enforcing optional style in a bot-like fashion without prior consensus, is disruptive and is never acceptable.Template:EfnTemplate:Efn

Unjustified changes from one acceptable, consistently applied style in an article to a different style may generally be reverted. Seek opportunities for commonality to avoid disputes over style.

If you believe an alternative style would be more appropriate for a particular article, seek consensus by discussing this at the article's talk page orTemplate:Sndif it raises an issue of more general application or with the MoS itselfTemplate:Sndat Wikipedia talk:Manual of Style. If a discussion does not result in consensus for the change at the article, continue to use the already-established style there. If discussion fails to reach a consensus regarding which of two or more competing styles to use at all, then default to the style that was used in the first post-stub version of the article in which one of the applicable styles appeared. (This fall-back position does not give unchallengeable primacy to that particular style during consensus discussion, nor give the editor who imposed that earliest style any more say in the discussion.)

Article titles, sections, and headings

Article titles

A title should be a recognizable name or description of the topic, balancing the criteria of being natural, sufficiently precise, concise, and consistent with those of related articles.

For formatting guidance see the Template:Section link section, noting the following:

• Capitalize the initial letter (except in rare cases, such as Template:Xt), but otherwise follow sentence caseTemplate:Efn (Template:Xt), not title case (Template:!xt), except where title case would be used in ordinary prose. See Wikipedia:Naming conventions (capitalization).
• To italicize, add Template:Tlx near the top of the article. For mixed situations, use Template:Tl, e.g., {{DISPLAYTITLE:Template:ZwspInterpretations of ''2001: A Space Odyssey''}}, instead. Use of italics should conform to Template:Section link.
• Do not use articles (a, an, or the) as the first word (Template:Xt, not Template:!xt), unless it is an inseparable part of a name (Template:Xt) or of the title of a work (Template:Xt, Template:Xt).
• Normally use nouns or noun phrases: Template:Xt, not Template:!xt.Template:Efn
• The final character should not be punctuation unless it is an inseparable part of a name (Template:Xt, Template:Xt) or an abbreviation (Template:Xt), or when a closing round bracket or quotation mark is required (Template:Xt).
• Whenever quotation marks or apostrophe-like variants appear, add a redirect for the same title using apostrophes.Template:Efn

Subject both to the above and to Wikipedia:Article titles, the rest of the MoS, particularly Template:Section link, applies also to the title.

Section organization

An article's content should begin with an introductory lead sectionTemplate:Snda concise summary of the articleTemplate:Sndwhich is never divided into sections Template:Crossref. The remainder of the article is typically divided into sections.

Infoboxes, images, and other related content in the lead section must be right-aligned.

Certain standardized templates and wikitext that are not sections go at the very top of the article, before the content of the lead section, and in the following order:

• A short description, with the Template:Tlx template
• A disambiguation hatnote, most of the time with the Template:Tlx template Template:Crossref
• No-output templates that indicate the article's established date format and English-language variety, if any (e.g., Template:Tlx, Template:Tlx)
• Banner-type maintenance templates, Dispute and Cleanup templates for article-wide issues that have been flagged (otherwise used at the top of a specific section, after any sectional hatnote such as Template:Tlx)
• An infobox, which is optional (except in special cases like Template:Tlx and Template:Tlx, or a variant thereof, at applicable articles); usually also includes the first image
• An introductory image, when an infobox is not used, or an additional image is desired for the lead section (for unusually long leads, a second image can be placed midway through the lead text)

In the Vector 2022 skin, the table of contents is separate from the article content. In some older skins, a navigable table of contents appears automatically just after the lead if an article has at least four section headings.

If the topic of a section is covered in more detail in a dedicated article Template:Crossref, insert Template:Tlx or Template:Tlx immediately under the section heading.

As explained in detail in Template:Slink, several kinds of material (mostly optional) may appear after the main body of the article, in the following order:

• Books or other works created by the subject of the article, under a section heading "Works", "Publications", "Discography", "Filmography", etc. as appropriate (avoid "Bibliography", confusable with reference citations)
• Internal links to related English Wikipedia articles, with section heading "See also"
• Notes and references, with a section heading "Notes" or "References" (usually the latter), or a separate section for each in this order Template:Crossref; avoid "Bibliography", confusable with the subject's works
• Relevant books, articles, or other publications that have not been used as sources; use the section heading "Further reading"; be highly selective, as Wikipedia is not a bibliographic directory
• Relevant and appropriate websites that have not been used as sources and do not appear in the earlier appendices, using the heading "External links", which may be made a subsection of "Further reading" (or such links can be integrated directly into the "Further reading" list instead); link templates for sister-project content also usually go at the top of this section when it is present (otherwise in the last section on the page)
• The following final items never take section headings:
  • Internal links organized into navigational boxes
  • Authority control metadata, if needed, using Template:Tlx (distinguishes uses of the same name for two subjects, or multiple names for one subject)
  • Categories, which should be the very last material in the article's source code if there are no stub templates
  • Stub templates, if needed, which should follow the categories

Stand-alone list articles have some additional layout considerations.

Section headings

Section headings should generally follow the guidance for article titles above and be presented in sentence case (Template:Xt), not title case (Template:!xt).Template:Efn

The heading must be on its own line, with one blank line just before it; a blank line just after is optional and ignored (but do not use two blank lines, before or after, because that will add unwanted visible space). Do not misuse description list markup (";") to create pseudo-headings.

As a matter of consistent style, section headings should not:

• redundantly refer back to the subject of the article, e.g., Template:Xt, not Template:!xt or Template:!xt.
• refer to a higher-level heading, unless doing so is shorter or clearer.
• be numbered or lettered as an outline.
• be phrased as a question, e.g., Template:Xt, not Template:!xt.
• use color or unusual fonts that may cause accessibility problems.
• be wrapped in markup, such as bold and italics, which may break their display and cause other accessibility issues.

Wikimarkup

For technical reasons, section headings should be unique within a page (so that section links work) and should not contain:

• links, especially where only part of a heading is linked.
• images or icons.
• <math> markup.
• citations or footnotes.
• template transclusions.Template:Efn

These technical restrictions are necessary to avoid technical complications and are not subject to override by local consensus.

Template:Short Hidden comments referring to a section heading or a whole section are best placed in the line below the heading. They can also be placed within the same line as the heading, but in that case they must be Template:Em the == == markup:Template:Efn Template:Block indent

Anchors

Before changing a heading, consider whether you might be breaking existing links to it.

If there are many links to the old title,Template:Efn create an anchor with that title to ensure that these still work. Similarly, when linking to a section, leave an invisible comment at the heading of the target section, naming the linking articles, so that if the heading is later altered these can be easily fixed, or alternatively another anchor can be created if there are many.Template:Efn For example:

== {{subst:Anchor|Consequences}} Implications ==
<!-- Section linked from [[Richard Dawkins]], [[Daniel Dennett]]. -->

which will be saved in the article as:

== <span class="anchor" id="Consequences"></span> Implications ==
<!-- Section linked from [[Richard Dawkins]], [[Daniel Dennett]]. -->

The advantage of using Template:Tlxs, or simply inserting the Template:Tag tags directly, is that when edits are made to the section in the future, the anchor will not be included in page history entries as part of the section name. When Template:Tlx is used directly, that undesirable behavior does occur. When inserting the span directly, Template:Em abbreviate it by using a self-closing tag, as in Template:!mxt, since in HTML5 that XML-style syntax is valid only for certain tags, such as <br/>. See Template:Section link for further discussion.

Heading-like material

The guidance above for section headings, specifically sentence case, redundancy, images and questions, also applies to table headings (and of table columns and rows). However, table headings can incorporate citations and may begin with, or be, numbers. Unlike page headings, table headers do not automatically generate link anchors. Aside from sentence case in glossaries, the heading advice also applies to the term entries in description lists. If using template-structured glossaries, terms will automatically have link anchors, but will not otherwise. Citations for description-list content go in the Template:Tl or Template:Tl element, as needed.

National varieties of English

National varieties of English (for example, American English or British English) differ in vocabulary (elevator vs. liftTemplate:Hairspace), spelling (center vs. centre), and occasionally grammar Template:Crossref. Articles such as English plurals and Comparison of American and British English provide information about such differences. All national varieties of Standard English are equally acceptable on English Wikipedia, which uses a formal, encyclopedic register or tone.

An article's date formatting (Template:Xt vs. Template:Xt) is also related to national varieties of EnglishTemplate:Sndsee MOS:DATEFORMAT and especially MOS:DATETIES and MOS:DATEVAR.

Consistency within articles

The conventions of a particular variety of Standard English should be followed consistently within a given article. Exceptions include:

• Quotations and titles of works (such as books, films, and music) should be given as they appear in sources. However, there are certain situations where this principle is not followed in order to maintain a level of typographic conformity across the encyclopedia. Template:Crossref
• Proper names use the subject's own spelling, e.g., Template:Xt; Template:Xt.
• For articles about chemistry-related topics, the international standard spellings Template:Xt, Template:Xt, Template:Xt (and derivative terms) should be used regardless of the variety of English otherwise employed in the article. Template:Crossref

Opportunities for commonality

For an international encyclopedia, using vocabulary common to all varieties of English is preferable.

• Use universally accepted terms rather than those less widely distributed, especially in titles. For example, [[Glasses|Template:Xt]] is preferred to the national varieties Template:!xt (British English) and Template:!xt (American English); [[Ten million|Template:Xt]] is preferable to [[crore|Template:!xt]] (Indian English).
• If a variant spelling appears in a title, make a redirect page to accommodate the others, as with artefact and artifact, so that all variants can be used in searches and linking.
• Terms that differ between varieties of English, or that have divergent meanings, may be glossed to prevent confusion, for example, Template:Xt.
• Use a commonly understood word or phrase in preference to one that has a different meaning because of national differences (rather than Template:!xt, use Template:Xt or Template:Xt, as appropriate), except in technical contexts where such substitution would be inappropriate (Template:Xt; Template:Xt).
• When more than one variant spelling exists within a national standard variety of English, the most commonly used current variant (across all varieties of Standard English) should usually be preferred, except where the less common spelling has a specific usage in a specialized context, e.g., connexion in Methodist connexionalism.

Strong national ties to a topic

An article on a topic that has strong ties to a particular English-speaking nation should use the standard (formal, not colloquial) English of that nation. For example: Template:Columns-list

For topics with strong ties to the Commonwealth of Nations, or multiple Commonwealth countries or other former British territories, use British spelling.

Retaining the existing variety

When an English variety's consistent usage has been established in an article, maintain it in the absence of consensus to the contrary. There is only very exceptionally (such as when a topic has strong national ties, or the change reduces ambiguity) a valid reason for changing from one acceptable option to another. When no English variety has been established and discussion does not resolve the issue, use the variety found in the first post-stub revision that introduced an identifiable variety. An exception to this is do not change the variety of English within a quotation.

The established variety in a given article is documented by placing the appropriate Use X English template on the article page. The appropriate variety of English template can also be placed on its talk page.

An article should not be edited or renamed simply to switch from one variety of English to another. Template:Tlxs may be placed on an editor's talk page to explain this.

Capital letters

Wikipedia article titles and section headings use sentence case, not title case; see Wikipedia:Article titles and Template:Section link. For capitalization of list items, see Template:Section link. Other points concerning capitalization are summarized below. Full information can be found at Wikipedia:Manual of Style/Capital letters. The central point is that Wikipedia does not capitalize something unless it is consistently capitalized in a substantial majority of independent, reliable sources.

Capitalization of The

Generally, do not capitalize the word the in mid-sentence: Template:Xt, not Template:!xt. Conventional exceptions include certain proper names (Template:Xt) and most titles of creative works (Template:XtTemplate:Sndbut be aware that the might not be part of the title itself, e.g., Template:Xt).

There are special considerations for band names, institution names, nicknames, titles of works, and trademarks.

Titles of works

The English-language titles of compositions (books and other print works, songs and other audio works, films and other visual media works, paintings and other artworks, etc.) are given in Template:Em, in which every word is given an initial capital except for certain less important words (as detailed at Template:Section link). The first and last words in an English-language title are always capitalized.

• Template:Em Template:Xt
• Template:Em Template:Xt

Capitalization in non-English language titles varies, even over time within the same language; generally, retain the style of the original for modern works, and follow the usage in currentTemplate:Efn English-language reliable sources for historical works. When written in the Latin alphabet, many of these items should also be in italics, or enclosed in quotation marks.

• Template:Em Template:Xt
• Template:Em Template:Xt

Titles of people

• In generic use, use lower case for words such as president, king, and emperor (Template:Xt; Template:Xt; Template:Xt).
• Directly before the person's name, such words begin with a capital letter (Template:Xt, not Template:!xt). Standard or commonly used names of an office are treated as proper names (Template:Xt; Template:Xt; Template:Xt). Royal styles take capitals (Template:Xt; Template:Xt); exceptions may apply for particular offices.

Religions, deities, philosophies, doctrines

• Religions, sects, and churches and their followers (in noun or adjective form) start with a capital letter. Generally, "the" is not capitalized before such names (Template:Xt, not Template:!xt).
• Religious texts are capitalized, but often not italicized (Template:Xt, Template:Xt, Template:Xt, Template:Xt, Template:Xt). Do not capitalize "the" when using it in this way. Some derived adjectives are capitalized by convention, and some are not (Template:Xt, but Template:Xt); if unsure, check a dictionary.
• Honorifics for deities, including proper names and titles, start with a capital letter (Template:Xt, Template:Xt, Template:Xt, Template:Xt, Template:Xt, Template:Xt, Template:Xt). Do not capitalize "the" in such cases or when referring to major religious figures or characters from mythology (Template:Xt, Template:Xt, Template:Xt). Common nouns for deities and religious figures are not capitalized (Template:Xt; Template:Xt; Template:Xt).
• Pronouns for figures of veneration or worship are not capitalized, even if capitalized in a religion's scriptures (Template:Xt).
• Broad categories of mythical or legendary beings start with lower-case letters (Template:Xt, Template:Xt, Template:Xt, Template:Xt, Template:Xt), although in works of fantasy, such as the novels of J. R. R. Tolkien and some video games, initial capitals are sometimes used to indicate that the beings form a culture or race in a fictional universe. Capitalize the names or titles of individual creatures (Template:Xt, Template:Xt) and of groups whose name and membership are fixed (Template:Xt, Template:Xt). Generalized references are not capitalized (Template:Xt; Template:Xt; Template:Xt).
• Spiritual or religious events are capitalized only when referring to specific incidents or periods (Template:Xt and Template:Xt; but Template:Xt and Template:Xt).
• Philosophies, theories, movements, and doctrines use lower case unless the name derives from a proper name (Template:Xt) or has become a proper name (Template:Xt, a system of political thought; Template:Xt, a political party). Use lower case for doctrinal topics or canonical religious ideas (as opposed to specific events), even if they are capitalized by some religious adherents (Template:Xt, Template:Xt, Template:Xt).
• Platonic or transcendent ideals are capitalized in the context of philosophical doctrine (Template:Xt, Template:Xt); used more broadly, they are in lower case (Template:Xt). Use capitals for personifications represented in art (Template:Xt).
• Eponyms are capitalized ([[Edwardian era|Template:Xt]], [[De Morgan's laws|Template:Xt]], [[Alice in Wonderland syndrome|Template:Xt]], [[Plaster of Paris|Template:Xt]], [[Platonic idealism|Template:Xt]], [[Draconian constitution|Template:Xt]]), except in idiomatic uses disconnected from the original context and usually lower-cased in sources ([[Platonic relationship|Template:Xt]]; Template:Xt).Template:Efn An entire phrase in which an eponym is an adjective is not capitalized except when the phrase is itself a proper name (e.g., the title of a published work: [[The China Syndrome|Template:Xt]]).

Calendar items

• Months, days of the week, and holidays start with a capital letter (Template:Xt, Template:Xt; Template:Xt refers only to the US Independence DayTemplate:Sndotherwise Template:Xt or Template:Xt).
• Seasons are in lower case (Template:Xt; Template:Xt; Template:Xt), except in personifications or in proper names for periods or events (Template:Xt; Template:Xt).

Animals, plants, and other organisms

When using taxonomic ("scientific") names, capitalize and italicize the genus: Template:Xt, Template:Xt. (Supergenus and subgenus, when applicable, are treated the same way.) Italicize but do not capitalize taxonomic ranks at the level of species and below: Template:Xt, Template:Xt, Template:Xt; no exception is made for proper names forming part of scientific names. Higher taxa (order, family, etc.) are capitalized in Latin (Template:Xt, Template:Xt) but not in their English equivalents (Template:Xt, Template:Xt); they are not italicized in either form, except for viruses, where all names accepted by the ICTV are italicized (Template:Xt).

Cultivar and cultivar group names of plants are not italicized, and are capitalized (including the word Group in the name); cultivar names appear within single quotes (Template:Xt), while cultivar groups do not (Template:Xt).

English vernacular ("common") names are given in lower case in article prose ([[Plains zebra|Template:Xt]], [[Mountain maple|Template:Xt]], and [[Southwestern red-tailed hawk|Template:Xt]]) and in sentence case at the start of sentences and in other places where the first letter of the first word is capitalized.Template:Efn They are additionally capitalized where they contain proper names: [[Przewalski's horse|Template:Xt]], [[California condor|Template:Xt]], and [[Fair-maid-of-France|Template:Xt]]. This applies to species and subspecies, as in the previous examples, as well as to general names for groups or types of organism: [[Bird of prey|Template:Xt]], [[Oak|Template:Xt]], [[Great apes|Template:Xt]], [[Bryde's whales|Template:Xt]], [[Livestock guardian dog|Template:Xt]], [[Poodle|Template:Xt]], [[Van cat|Template:Xt]], [[Wolfdog|Template:Xt]]. When the common name coincides with a scientific taxon, do not capitalize or italicize, except where addressing the organism taxonomically: Template:Xt Non-English vernacular names, when relevant to include, are handled like any other non-English terms: italicized as such, and capitalized only if the rules of the native language require it. Non-English names that have become English-assimilated are treated as English ([[Ayahuasca|Template:Xt]], [[Okapi|Template:Xt]]).

Standardized breeds should generally retain the capitalization used in the breed standards.Template:Efn Examples: [[German Shepherd|Template:Xt]], [[Russian White goat|Template:Xt]], [[Berlin Short-faced Tumbler|Template:Xt]]. As with plant cultivars, this applies whether or not the included noun is a proper name, in contrast to how vernacular names of species are written. However, unlike cultivars, breeds are never put in single quotation marks, and their names are never part of a scientific name. A species term appended at the end for disambiguation ("cat", "hound", "horse", "swine", etc.) should not be capitalized, unless it is a part of the breed name itself and is consistently presented that way in the breed standards (rare cases include [[Norwegian Forest Cat|Template:Xt]] and [[American Quarter Horse|Template:Xt]]).

Create redirects from alternative capitalization and spelling forms of article titles, and from alternative names, e.g., Adélie Penguin, Adelie penguin, Adelie Penguin and Pygoscelis adeliae should all redirect to Adélie penguin.

Celestial bodies

The words sun, earth, moon, and solar system do not take capitals in general use (Template:Xt; Template:Xt). They are capitalized when the entity is personified (Template:Xt) or when used as the name of a specific body in a scientific or astronomical context (Template:Xt; but Template:Xt).

Names of planets, moons, asteroids, comets, stars, constellations, and galaxies are proper names, and therefore capitalized (Template:Xt). The first letter of every word in such a name is capitalized (Template:Xt and not Template:!xt; Template:Xt, not Template:!xt). Words such as comet and galaxy should be capitalized when they form part of a proper name, but not when they are used as a generic term (Template:Xt; Template:Xt).

Compass points

Do not capitalize directions such as north or their related forms (Template:Xt) except when they are parts of proper names (Template:Xt, Template:Xt, Template:Xt).

Capitalize names of regions if they have attained proper-name status, including informal conventional names (Template:Xt; Template:Xt), and derived terms for people (e.g., a Southerner as someone from the Southern United States). Do not capitalize descriptive names for regions that have not attained the status of proper names, such as Template:Xt.

Composite directions may or may not be hyphenated, depending on the variety of English adopted in the article. Template:Xt and Template:Xt are more common in American English; but Template:Xt and Template:Xt in British English. In cases such as Template:Xt and Template:Xt, use an en dash; see Template:Section link.

Proper names versus generic terms

Capitalize names of particular institutions (Template:Xt; Template:Xt) but not generic words for institutions (Template:Xt). Do not capitalize the at the start of an institution's name, regardless of the institution's preferred style. There are rare exceptions, when a leading The is represented by a T in the organization's acronym: Template:Xt.

Treat political or geographic units similarly: Template:Xt; Template:Xt. Do not mimic the style of local newspapers which refer to their municipality as the City or The City, except for the City of London in some circumstances.

This guidance extends to the output of institutions, companies, and other organizations. For example, the full name of legislation like Template:Xt would be capitalized, but subsequent references to Template:Xt would not.

Ligatures

Ligatures should be used in languages in which they are standard (hence Template:Xt is preferable to Template:Xt) but not in English (Template:Xt or Template:Xt, not Template:!xt), except in proper names (Template:Xt, not Template:!xt).

Abbreviations

Abbreviations are shortened forms of words or phrases. In strict analysis, they are distinct from contractions, which use an apostrophe (e.g., won't, see Template:Section link), and initialisms. An initialism is formed from some or all of the initial letters of words in a phrase. Below, references to abbreviations should be taken to include acronyms, and the term acronym should also apply to initialisms.

Write first occurrences in full

When an abbreviation will be used in an article, introduce it using the full expression, and the abbreviation in parentheses: Template:Block indent

Do not use capitals in the full version merely because capitals are used in the abbreviation: Template:!xt.

Except in special circumstances, common abbreviations (such as Template:Xt, Template:Xt, or Template:Xt) need not be expanded even on first use.

Plural forms

Pluralize acronyms by adding -s or -es: Template:Xt. Do not use a greengrocer's apostrophe to form plurals: Template:!xt.

Punctuation and spacing

An abbreviation may or may not be terminated with a full point (also called a period or full stop). A consistent style should be maintained within an article. North American usage is typically to end all abbreviations with a period/point (Template:Xt) but in common British and Australian usage, no period/point is used if the abbreviation (contraction) ends in the last letter of the unabbreviated form (Template:Xt) unless confusion could result. This is also common practice in scientific writing. Regardless of punctuation, words that are abbreviated to more than one letter are spaced (Template:Xt not Template:!xt or Template:!xt). There are some exceptions: Template:Xt Template:Crossref for "Philosophiae Doctor"; Template:Xt for "Bachelor of Veterinary Medicine". In most situations, Wikipedia uses no such punctuation inside acronyms and initialisms: Template:Xt, not Template:!xt

US and U.S.

Template:Xt is a commonly used abbreviation for Template:Xt, although Template:Xtn – with periods and without a space – remains common in North American publications, including in news journalism. Multiple American style guides, including The Chicago Manual of Style (since 2010), now deprecate Template:!xt and recommend Template:Xt.

For commonality reasons, use Template:Xt by default when abbreviating, but retain Template:Xtn in American or Canadian English articles in which it is already established, unless there is a good reason to change it. Because use of periods for abbreviations and acronyms should be consistent within any given article, always use Template:Xt in an article with other country abbreviations. In longer abbreviations that incorporate the country's initials (Template:Xt, Template:Xt), never use periods. When the United States is mentioned with one or more other countries in the same sentence, Template:Xt (or Template:Xtn) may be too informal, especially at the first mention or as a noun instead of an adjective (Template:Xt, not Template:!xt). Do not use the spaced Template:!xt or the archaic Template:!xt, except when quoting.

Do not use Template:!xt or Template:!xt except in a quotation, as part of a proper name (Template:Xt), or in certain technical and formal uses (e.g., the ISO 3166-1 alpha-3, FIFA, and IOC country codes).

Circa

To indicate approximately, the use of Template:Tlx, showing as Template:Circa, is preferred over circa, c., ca., or approx.

Avoid unwarranted use

Avoid abbreviations when they might confuse the reader, interrupt the flow, or appear informal. For example:

• Do not use Template:!xt for Template:Xt except in an infobox or table (in which case use Template:Tlx at first occurrence: Template:Xt).
• Do not use the legalism Template:!xt for Template:Xt.

Do not invent

Avoid devising new abbreviations, especially acronyms. For example, Template:Xtn is good as a Template:Em of Template:Xt, but neither it nor the reduction Template:!xt is used by the organization or by independent sources; use the original name and its official abbreviation, Template:Xt.

If it is necessary to abbreviate in a tight space, such as a column header in a table, use widely recognized abbreviations. For example, for Template:Xt, use Template:Xt and Template:Xt, with a link if the term has not already been written out in the article: Template:Xt. Do not make up initialisms such as Template:!xt.

HTML tags and templates

Either Template:Tag or Template:Tlx can be used for abbreviations and acronyms: Template:Tag or Template:Tlx will generate WHO; hovering over the rendered text causes a tooltip of the long form to pop up.

Ampersand

Template:Redirects In normal text and headings, use and instead of the ampersand (&): Template:Xt, not Template:!xt. But retain an ampersand when it is a legitimate part of the style of a proper noun, the title of a work, or a trademark, such as in Up & Down or AT&T. Elsewhere, ampersands may be used with consistency and discretion where space is extremely limited (e.g., tables and infoboxes). Quotations may be cautiously modified, especially for consistency where different editions are quoted, as modern editions of old texts routinely replace ampersands with and (just as they replace other disused glyphs, ligatures, and abbreviations). Another frequent permissible but not required use is in short bibliographic references to works by multiple authors, e.g.: Template:Xt.

Italics

Emphasis

Italics are used for emphasis, rather than boldface or capitals. But overuse diminishes its effect: consider rewriting instead.

Use Template:Tag or Template:Tlx for emphasis. This allows user style sheets to handle emphasis in a customized way, and helps reusers and translators.Template:Refn

• Correct: Template:Mxt
• Correct: Template:Mxt

Titles

Wiki143:Manual of Style/titles hatnote include Use italics for the titles of works (such as books, films, television series, named exhibitions, computer games, music albums, and artworks). The titles of articles, chapters, songs, episodes, storylines, research papers and other short works instead take double quotation marks.

Italics are not used for major religious works (Template:Xt, Template:Xt, Template:Xt). Many of these titles should also be in title case.

Words as words

Use italics when Template:Em a word or character Template:Crossref or a string of words up to one sentence (Template:Xt; Template:Xt). When a whole sentence is mentioned, double quotation marks may be used instead, with consistency (Template:Xt; or Template:Xt). Quotation marks may also be used for shorter material to avoid confusion, such as when italics are already heavily used in the page for another purpose (e.g., for many non-English words and phrases). Template:Em (to discuss grammar, wording, punctuation, etc.) is different from Template:Em (in which something is usually expressed on behalf of a quoted source). Quotation is done with quotation marks, never italics, nor both at once Template:Crossref

A closely related use of italics is when introducing or distinguishing terms: Template:Xt

Non-English words

Italics are indicated for non-English phrases and isolated non-English words that are not commonly used in everyday English. However, proper names (such as place names) in other languages are not usually italicized, nor are terms in non-Latin scripts. The Template:Tlx template and its variants support all ISO 639 language codes, correctly identifying the language and automatically italicizing for you. Please use these templates rather than just manually italicizing non-English material. Template:Crossref

Scientific names

Use italics for the scientific names of plants, animals, and all other organisms except viruses at the genus level and below (italicize Template:Xt and Template:Xt, but not Template:Xt). The hybrid sign is not italicized (Template:Xt), nor is the "connecting term" required in three-part botanical names (Template:Xt).

Quotations in italics

Do not put quotations in italics. Quotation marks (or block quoting) alone are sufficient and the correct ways to denote quotations. Italics should only be used if the quoted material would otherwise call for italics.

(See below.)

Italics within quotations

Use italics within quotations to reproduce emphasis that exists in the source material or to indicate the use of non-English words. The emphasis is better done with Template:Tlx. If it is not clear that the source already included italics (or some other styling) for emphasis, or to indicate when emphasis was not used in the original text but was editorially added later, add the editorial note Template:Xt or Template:Xt, respectively, after the quotation.

• For example: Template:Xt

Effect on nearby punctuation

Italicize only the elements of the sentence affected by the emphasis. Do not italicize surrounding punctuation.

• Template:Em Template:!xt (The question mark applies to the whole sentence, not just to the emphasized that, so it should not be italicized.)
• Template:Em Template:Xt
• Template:Em Template:Xt (The commas, the period, and the word and are not italicized.)

Quotations

Template:See Template:Redirects hereBrief quotations of copyrighted text may be used to illustrate a point, establish context, or attribute a point of view or idea. While quotations are an indispensable part of Wikipedia, excessive use of them is incompatible with an encyclopedic writing style and may be copyright infringement, so most of the content should be in the editor's own words. Consider paraphrasing quotations into plain and concise text when appropriate (while being aware that close paraphrasing can still violate copyright). Do not put quotations in italics unless the material would be italicized for some other reason.

Per the verifiability policy, direct quotations Template:Em be accompanied by an inline citation from a reliable source that supports the material. This is especially important in articles that are about or contain material about living or recently deceased people (BLPs).

Original wording

Quotations must be verifiably attributed, and the wording of the quoted text must be faithfully reproduced. This is referred to as the principle of minimal change. Where there is good reason to change the wording, square bracket the changed text; for example, Template:!xt might be quoted as Template:Xt. If there is a significant error in the original, follow it with Template:Tlx (producing Template:XtTemplate:Hsp) to show that the error was not made by Wikipedia. (for example, Template:Xt) However, insignificant spelling and typographic errors should simply be silently corrected (for example, correct Template:!xt to Template:Xt). When applied to text that is linked, the syntax of the template may be adjusted to Template:Tlx (producing [sic] in the resulting linked text; for example in the link: [sic] template).Template:Efn For the sake of accuracy and indexing, the titles of referenced sources should not be corrected for spelling, but minor typographic adjustments (like changing curly quotes to straight) may be made silently. Inline citations in the quoted text, to sources not used in the Wikipedia article, should be silently removed.

Use ellipses to indicate omissions from quoted text. Legitimate omissions include extraneous, irrelevant, or parenthetical words, and unintelligible speech (Template:!xt and Template:!xt), but do not omit text where doing so would remove important context or alter the meaning of the text. Vulgarities and obscenities should be shown exactly as they appear in the quoted source; Wikipedians should never bowdlerize words (Template:!xt), but if the text being quoted Template:Em does so, copy the text verbatim and use Template:Tlx to indicate that the text is quoted as shown in the source.

In direct quotations, retain dialectal and archaic spellings, including capitalization (but not archaic glyphs and ligatures, as detailed below in Template:Slink).

Point of view

Quotation should be used, with attribution, to present emotive opinions that cannot be expressed in Wikipedia's own voice, but never to present cultural norms as simply opinional:

• Acceptable: Template:Xt
• Unacceptable: Template:!xt

Concise opinions that are not overly emotive can often be reported with attribution instead of direct quotation. Use of quotation marks around simple descriptive terms can imply something doubtful regarding the material being quoted; sarcasm or weasel words such as supposedly or so-called, might be inferred.

• Permissible: Template:Xt
• Unnecessary and may imply doubt: Template:!xt
• Should be quoted: Template:Xt

Typographic conformity

A quotation is not a facsimile and, in most cases, it is not a requirement that the original formatting be preserved. Formatting and other purely typographical elements of quoted textTemplate:Efn should be adapted to English Wikipedia's conventions without comment, provided that doing so will not change or obscure meaning or intent of the text. These are alterations which make no difference when the text is read aloud, for example:

• Normalize dashes and hyphens: see Template:Section link. Use the style chosen for the article: unspaced em dash or spaced en dash.
• Convert apostrophes and quotation marks to Wikipedia's style:
  • These should be straight, not curly or slanted. See Template:Section link.
  • When quoting a quotation that itself contains a quotation, alternate between using double and single quotes for each quotation. See Template:Section link for details.
• When quoting text from non-English languages, the outer punctuation should follow the Manual of Style for English quote marks. If there are nested quotations, follow the rules for correct punctuation in that language. If there are multiple styles for a language, the one used by the Wikipedia for that language is preferred unless the punctuation itself is under discussion.

  Template:Xt

• Remove spaces before punctuation such as periods and colons.
• Generally preserve bold and italics Template:Crossref, but most other styling should be altered. Template:!xt, Template:!xt within words, Template:!xt, Template:!xt, Template:!xt, etc. should generally be normalized to plain text. If it Template:Em indicates emphasis, use italic Template:Em (Template:Tlx) or, in an already-italic passage, boldface (with Template:Tlx). For titles of books, articles, poems, and so forth, use italics or quotation marks following the guidance for titles. Italics can also be added to mark up non-English terms (with the Template:Tlx template), for an organism's scientific name, and to indicate a words-as-words usage.
• Expand an abbreviation (not already used in the content before the quotation) as a square-bracketed change, or explain it using Template:Tlx.
• Normalize archaic glyphs and ligatures in English that are unnecessary to the meaning (except in proper names and for languages where ligatures are standard, per Template:Section link and MOS:LIGATURE). Examples include æ→ae, œ→oe, ſ→s, and þ^e→the.

However, national varieties should not be changed, as these may involve changes in vocabulary. For example, a quotation from a British source should retain British spelling, even in an article that otherwise uses American spelling. Template:Crossref

Numbers also usually should not be reformatted.

Direct quotation should not be used to preserve the formatting preferred by an external publisher (especially when the material would otherwise be unchanged), as this tends to have the effect of scare-quoting:

• Template:Em: Template:Xt
• Template:Em: Template:!xt

Italics can be used to mark a particular usage as a term of art (a case of "words as words"), especially when it is unfamiliar or should not be reworded by a non-expert:

• Template:Em: Template:Xt

When quoting a complete sentence, it is usually recommended to keep the first word capitalized. However, if the quoted passage has been integrated into the surrounding sentence (for example, with an introduction such as "Template:Var said that"), the original capital letter may be lower-cased.

• Template:Xt
• Template:Xt
• Template:Xt

It is normally unnecessary to note changes in capitalization. However, for more precision, the altered letter may be put inside square brackets: Template:Nobr

• Template:Xt

Attribution

The reader must be able to determine the source of any quotation, at the very least via a footnote. The source must be named Template:Em if the quotation is an opinion Template:Crossref. When attributing a quotation, avoid characterizing it in a biased manner.

Quotations within quotations

See Template:Section link.

Linking

Be conservative when linking within quotations; link only to targets that correspond to the meaning clearly intended by the quote's author. Where possible, link from text outside of the quotation instead – either before it or soon after. (If quoting hypertext, add an editorial note, Template:Xt or Template:Xt, as appropriate, to avoid ambiguity as to whether the link was made by the original author.)

Block quotations

Format a long quotation (more than about forty words or a few hundred characters, or consisting of more than one paragraph, regardless of length) as a block quotation, using the Template:Tlx template. The text presented in block quotations and quote boxes (see below) should not itself be enclosed in quotation marks (including large, "decorative"-type quotation marks). Block quotations and quote boxes using a colored background are also discouraged.

Use Template:Tnull and similar markup only for actual quotations; indentation for other purposes is done differently.

It is conventional to precede a block quotation with an introductory sentence (or sentence fragment) and append the source citation to that line. Alternatively, the Template:Tnull template provides parameters for attribution and citation which will appear below the quotation. Template:Crossref This below-quotation attribution style is intended for famous quotations and is unusual in articles because it may strike an inappropriate tone. A quotation with no cited source should be flagged with Template:Tlx, or deleted.

Since line breaks and indentation are generally ignored inside Template:Tnull or Template:Tag, use Template:Xtag or Template:Tlx for poetry, lyrics, and similar material. Such material can also be quoted inline, with line breaks indicated by {{nbsp}}/, and paragraph or stanza breaks by {{nbsp}}//. For example: Template:Xt

A Template:Tlx is an alternative to an inline quote or a block quote. Quote boxes are displayed in a stand-alone manner (similar to images) and are best suited to noteworthy or important quotations. They can create point of view or undue weight issues, because the quotations are not put in context or integrated into the text of the article proper. They must therefore be used with particular care.

Pull quotes do not belong in Wikipedia articles. These are the news and magazine style of "pulling" material already in the article to reuse it in attention-grabbing decorative quotations. This unencyclopedic approach is a form of editorializing, produces out-of-context and undue emphasis, and may lead the reader to conclusions not supported in the material.

Excessive quotation of copyrighted text (whether or not formatted as a blockquote, and even if credited to its source) is prohibited. See WP:COPYQUOTE.

Non-English quotations

Quotations from non-English language sources should appear with a translation into English, preferably a modernTemplate:Efn one. Quotations that are translations should be explicitly distinguished from those that are not. Indicate the original source of a translation (if it is available, and not first published within Wikipedia), and the original language (if that is not clear from the context).

If the original, untranslated text is available, provide a reference for it or include it, as appropriate.

When editors themselves translate text into English,Template:Efn care must always be taken to include the original text, Template:Em (except for non-Latin-based writing systems, and best done with the Template:Tlx or Template:Tlx templates which both italicize as appropriate and provide language metadata); and to use actual and (if at all possible) common English words in the translation. Unless you are certain of your competency to translate something, see Wikipedia:Translation for assistance.

Punctuation

Apostrophes

• Use straight apostrophes (

1. REDIRECT Template:Large

Template:Redirect category shell), not curly apostrophes (

1. REDIRECT Template:Large

Template:Redirect category shell).Template:Efn Do not use accent marks or backticks (

1. REDIRECT Template:Large

Template:Redirect category shell) as apostrophes.

• Templates such as Template:Tlx and Template:Tlx are helpful when an apostrophe (or single quote) appears at the beginning or end of text in italics or bold, because italics and bold are themselves indicated by sequences of single quotes.
  • When an apostrophe follows italicized text, Template:Tlx or Template:Tlx can be used to additionally prevent the last letter of the right-leaning text from intersecting the apostrophe. Example: Template:Xt (markup: Template:Nobreak).
• Letters resembling apostrophes and curly quotes, such as the ʻokina (Template:MxtTemplate:Sndinserted using Template:Tlx), saltillo (Template:MxtTemplate:SndTemplate:Tlx), Hebrew ayin or Arabic ʿayn (Template:MxtTemplate:SndTemplate:Tlx), and Arabic hamza (Template:MxtTemplate:SndTemplate:Tlx), should be represented by those templates or by their respective Unicode characters.
  • Templates cannot be used in article titles; use the corresponding Unicode character directly. Per WP:TITLESPECIALCHARACTERS, also make a redirect from the ASCII form to aid searches. Forms without apostrophe-like characters are sometimes preferred by WP:COMMONNAME (e.g. Hawaii but not Kealiʻi Reichel).

  Template:Crossref

• For Wade–Giles romanizations of Mandarin Chinese, use Template:Tlx.
• For languages with ejective consonants and the like, use Template:Tlx.
• For the Cyrillic soft sign, when indicated at all, use Template:Tlx or Template:Tlx.
• For usage of the possessive apostrophe, see Template:Section link.
• For further treatment of apostrophe usage (possessive, elision, formation of certain plurals, non-English language issues), see the article Apostrophe.

Quotation marks

In the material below, the term quotation includes conventional uses of quotation marks such as for titles of songs, chapters, episodes, and so on. Quotation marks are also used in other contexts, such as in cultivar names.

Quotation characters

• Use Template:Xt quotation marks, not Template:!xt ones. (For single-apostrophe quotes: Template:Xt, not Template:!xt.)Template:Efn
• Do not use accent marks, backticks (Template:!xt), low-high (Template:!xt), corner brackets (Template:!xt), or guillemet (Template:!xt) marks as quotation marks (except when such marks are Template:Em to quoted non-English textTemplate:Sndsee Template:Slink). The symbols Template:!xt and Template:!xt seen in edit window dropdowns are prime and double prime: these are used to designate units of angular measurement, and not as apostrophes or quote marks.
• Quotation marks and apostrophes in imported material should be changed if necessary to comply with the above.

Double or single

Most quotations take double quotation marks (Template:Xt).Template:Efn Exceptions:

• Plant cultivars take single quotation marks (Template:Xt; see Wikipedia:Naming conventions (flora)).
• Glosses that translate or define unfamiliar terms (when using the words as words) take single quotes; simple glosses require no comma before the definition (Template:Xt). The Template:Tl template can be used for this; e.g. Template:Tlx Template:Tlx yields: Template:Gloss.

For a quotation within a quotation

Use single quotes:

• Template:Xt

For deeper nesting, alternate between single and double quotes:

• Template:Xt

For quote marks in immediate succession, add a sliver of space by using Template:Tl, Template:Tl, or (as in the example just given) Template:Tl:

• Template:Xt Markup: He announced, "The answer was 'Yes!Template:Tl
• Template:!xt (simply jamming things together looks bad in most fonts)
• Template:!xt (a regular space is too much)

Article openings

In the bolded text typically appearing at the opening of an article:

• Any quotation marks that are part of the title should be in bold just like the rest of the title.
  • From "A" Is for Alibi: Template:Xt
• Quotation marks not part of the article title should not be bolded.
  • From Jabberwocky: Template:Xt
  • From Babe Ruth: Template:Xt Template:Crossref

Punctuation before quotations

If a non-quoted but otherwise identical construction would work grammatically without a comma, using a comma before a quotation embedded within a sentence is optional:

• Template:Xt (Cf. the non-quotation Template:Xt)
• Template:Xt

The comma-free approach is often used with partial quotations:

• Template:Xt

A comma is required when it would be present in the same construction if none of the material were a quotation:

• Template:Xt

Do not insert a comma if it would confuse or alter the meaning:

• Template:Xt (Accurate quote of a statement about Template:Em childrenTemplate:Sndspecifically those children "who are coming to termsTemplate:Nbsp...")
• Template:!xt (Changes the meaning to imply Jenner was expressing concern about Template:Em children, while separately observing that children, in general, "are coming to termsTemplate:Nbsp...")

It is clearer to use a colon to introduce a quotation if it forms a complete sentence, and this should always be done for multi-sentence quotations:

• Template:Xt
• Template:Xt

No additional punctuation is necessary for an explicit words-as-words scenario:

• Template:Xt

Names and titles

Quotation marks should be used for the following names and titles: Template:Columns-list

Do not use quotation marks or italics for: Template:Columns-list

Many, but not all, of the above items should also be in title case.

Punctuation inside or outside

Use the logical quotation style in all articles, regardless of the variety of English in which they are written. Include terminal punctuation within the quotation marks only if it was present in the original material, and otherwise place it after the closing quotation mark. For the most part, this means treating periods and commas in the same way as question marks: keep them inside the quotation marks if they apply only to the quoted material and outside if they apply to the whole sentence. Examples are given below.

• Template:Em Template:Xt (question mark applies to whole sentence)
• Template:Em Template:!xt (incorrect to apply the question mark to the quotation)
• Template:Em Template:Xt (question mark applies to quoted material only)

If the quotation is a single word or a sentence fragment, place the terminal punctuation outside the closing quotation mark. When quoting a full sentence, the end of which coincides with the end of the sentence containing it, place terminal punctuation inside the closing quotation mark.

• Template:Xt
• Template:Xt

If the quoted sentence is followed by a clause that should be preceded by a comma, omit the full stop (period), and do not replace it with a comma Template:Em the quotation.Template:Efn Other terminal punctuation, such as question marks or exclamation marks, may be retained.

• Template:Xt
• Template:Xt

If the quoted sentence is followed by a clause identifying the speaker, use a comma outside the quotation mark instead of a full stop inside it, but retain any other terminal punctuation, such as a question mark.

• Template:Xt
• Template:Xt

Do not follow quoted words or fragments with commas inside the quotation marks, except where a longer quotation has been broken up and the comma is part of the full quotation.

• Template:Em Template:Xt
• Template:Em Template:Xt
• Template:Em Template:Xt
• Template:Em Template:!xt

Quotation marks and external links

External links to article titles should have the title in quotes inside the link. The CS1 and CS2 citation templates do this automatically, and untemplated references should do the same.

• Template:Em Template:Xt (Using Template:Tl)
• Template:Em Template:Xt (Untemplated)
• Template:Em Template:!xt (Untemplated)

Quotation marks and internal links

Internal links (wikilinks) accompanied by quotation marks should usually have the quotes outside the link. This applies to titles of works in quotation marks (songs, episodes, etc.)

• Template:Em Template:Xt (Using "[[ ]]".)
• Template:Em Template:!xt (Using [[" "]].)

However, quotation marks are needed inside wikilinks when the quotation mark is part of the link, or where the linked display text includes quotation marks indicating slang, nicknames, common names, or similar usage.

• Template:Em Template:Xt
• Template:Em Template:Xt
• Template:Em Template:Xt
• Template:Em Template:Xt
• Template:Em Template:Xt

Brackets and parentheses

This section applies to both round brackets Template:Xt, often called parentheses, and square brackets Template:Xt.

If a sentence contains a bracketed phrase, place the sentence punctuation outside the brackets Template:Xt However, where one or more sentences are wholly inside brackets, place their punctuation inside the brackets. There should be no space next to the inner side of a bracket. An opening bracket should usually be preceded by a space. This may not be the case if it is preceded by an opening quotation mark, another opening bracket, or a portion of a word:

• Template:Xt
• Template:Xt
• Template:Xt
• Template:Xt

There should be a space after a closing bracket, except where a punctuation mark follows (though a spaced dash would still be spaced after a closing bracket) and in unusual cases similar to those listed for opening brackets.

Avoid adjacent sets of brackets. Either put the parenthetical phrases in one set separated by semicolons, or rewrite:

• Template:Em: Template:!xt
• Template:Em: Template:Xt
• Template:Em: Template:Xt

Square brackets are used to indicate editorial replacements and insertions within quotations, though this should never alter the intended meaning. They serve three main purposes:

• To clarify: Template:Xt, where this was the intended meaning, but the type of school was unstated in the original sentence.
• To reduce the size of a quotation: Template:Xt may be reduced to Template:Xt. When an ellipsis (Template:Xt) is used to indicate that material is removed from a direct quotation, it should not normally be bracketed. Template:Crossref
• To make the grammar work: Referring to someone's statement Template:Xt, one could properly write Template:Xt.

If a sentence includes subsidiary material enclosed in square or round brackets, it must still carry terminal punctuation Template:Em those brackets, regardless of any punctuation within the brackets. Template:Block indent However, if the entire sentence is within brackets, the closing punctuation falls within the brackets. Template:Xt

Brackets and linking

Square brackets inside of links must be escaped:

He said, "Template:Mxt answered."	He said, "John [Doe] answered."
He said, "Template:Mxt answered."	He said, "John [Doe] answered."
Template:Mxt	On the first day [etc.]
Template:Mxt	On the first day [etc.]

The Template:Xtag markup can also be used: Template:Tag or Template:Tag.

If a URL itself contains square brackets, the wiki-text should use the URL-encoded form https://example.com/foo.php?query=Template:BxtxxxTemplate:Bxtyyy, rather than ...query=Template:!bxtxxxTemplate:!bxtyyy. This will avoid truncation of the link after xxx.

Ellipses

Use an ellipsis (plural ellipses) if material is omitted in the course of a quotation, unless square brackets are used to gloss the quotation Template:Crossref.

• Wikipedia's style for an ellipsis is three unspaced dots (Template:Xt); do not use the precomposed ellipsis character (Template:!xt) or three dots separated by spaces Template:Nobr
• Generally, use a non-breaking space before an ellipsis, and a regular space after it: Template:Nobr
  • But where an ellipsis is immediately followed by any of . ? ! : ; , ) ] } or by a closing quotation mark (single or double), use a non-breaking space before the ellipsis, and no space after it:

    Template:Xt

    Template:Xt (Place terminal punctuation after an ellipsis only if it is textually important, as is often the case with exclamation marks and question marks but rarely with periods.)

  • Or, if the ellipsis immediately follows a quotation mark, use no space before the ellipsis, and a non-breaking space after it:

    Template:Xt

• In mathematics formulas, formatted using html or wikimarkup, use three unspaced dots rather than the precomposed ellipsis character as above. However, in LaTeX-formatted mathematics formulas, use the proper LaTeX markup for lowered dots (\dots, $\dots$) rather than three dots. Do not replace precomposed characters that have dots in other positions (such as centered or diagonal, ⋯, ⋰, or ⋱).

Template:Visible anchor

Three dots are occasionally used to represent a pause in or suspense of speech, in which case the punctuation is retained in its original form: Template:Xt. When it indicates an incomplete word, no space is used between the word fragment(s) and the ellipsis: Template:Xt

With square brackets

Square brackets may be placed around an ellipsis that indicates omitted text to distinguish it from an ellipsis that is part of the quoted text: Template:Xt. In this example, the first ellipsis is part of the quoted text and the second ellipsis (in square brackets) indicates omitted text.

Commas

A pair of commas can bracket an appositive, relative clause, or parenthetical phrase (as can brackets or dashes, though with greater interruption of the sentence). For example:

Always use a pair of commas for this, unless another punctuation mark takes the place of the second comma: Template:Block indent

Don't let other punctuation distract you from the need for a comma, especially when the comma collides with a bracket or parenthesis:

In geographical references that include multiple levels of subordinate divisions (e.g. city, state/province, country), a comma separates each element and follows the last element unless followed by terminal punctuation or a closing parenthesis. The last element is treated as parenthetical.

Also include commas when the geographical element is used as a disambiguator:

Include a second comma also when a construction with a comma modifies a noun or compound noun:

Dates in month–day–year format require a comma after the day, as well as after the year, unless followed by other punctuation. The last element is treated as parenthetical.

Place quotation marks by following Template:Section link. This is known as "logical quotation". Template:Block indent

A comma may be included before a quotation embedded within a sentence Template:Crossref.

Serial commas

A serial comma (sometimes also known as an Oxford comma or Harvard comma) is a comma used immediately before a conjunction (and, or, nor) in a list of three or more items.

Editors may use either convention so long as each article is internally consistent. Serial commas are more helpful when article text is complex, such as a list with multi-word items (especially if one contains its own "andTemplate:-") or a series of probably unfamiliar terms.

However, there are cases in which either omitting or including the serial comma results in ambiguity:

In such cases of ambiguity, clarify one of four ways:

• Add or remove the serial comma.
• Use separate sentences, bullet lists, or some other structural change to clarify.
• Recast the sentence ("friends" case):
  • To list two people: Template:Xt
    • Clearer: Template:Xt
  • To list several people:

    Template:Xt or

    Template:Xt.

    • But not: Template:!xtTemplate:Spndintroduces ambiguity about her.
• Recast the sentence ("friend" case):
  • To list two people: Template:Xt
    • Or be more specific when possible: Template:Xt
  • To list three people: Template:Xt
    • Clarity with gender-specific terms such as mother can be tricky; Template:!xt is unclear because readers may not know Kim Thayil is male and wouldn't be the same person as the mother.
    • Clearer: Template:Xt or Template:Xt.

Colons

A colon (Template:Xt) introduces something that demonstrates, explains, or modifies what has come before, or is a list of items that has just been introduced. The items in such a list may be separated by commas, or if they are more complex and perhaps themselves contain commas, the items should be separated by semicolons or arranged in a bulleted list.

A colon may also be used to introduce direct speech enclosed within quotation marks. Template:Crossref

In most cases, a colon works best with a complete grammatical sentence before it. When what follows the colon is also a complete sentence, start it with a capital letter, but otherwise do not capitalize after a colon except where doing so is needed for another reason, such as for a proper name. When a colon is being used as a separator in an article title, section heading, or list item, editors may choose whether to capitalize what follows, taking into consideration the existing practice and consistency with related articles.

Except in technical usage (Template:Xt), no sentence should contain multiple colons, no space should precede a colon, and a space (but never a hyphen or dash) should follow the colon.

Semicolons

A semicolon (Template:Xt) is sometimes an alternative to a full stop (period), enabling related material to be kept in the same sentence; it marks a more decisive division in a sentence than a comma. If the semicolon separates clauses, normally each clause must be independent (meaning that it could stand on its own as a sentence). In many cases, only a comma or only a semicolon will be correct in a given sentence.

Template:Em Template:Xt Template:Em Template:!xt

Above, "Though he had been here before" cannot stand on its own as a sentence, and therefore is not an independent clause.

Template:Em Template:Xt Template:Em Template:!xt

This incorrect use of a comma between two independent clauses is known as a comma splice; however, in certain kinds of cases, a comma may be used where a semicolon would seem to be called for:

Template:Em: Template:Xt (two brief clauses in an aphorism; see Ars longa, vita brevis) Template:Em: Template:Xt (reporting brisk conversation, such as this reply of Newton's)

A sentence may contain several semicolons, especially when the clauses are parallel in construction and meaning; multiple unrelated semicolons are often signs that the sentence should be divided into shorter sentences or otherwise refashioned.

Template:Em: Template:!xt Template:Em: Template:Xt

Semicolons are used in addition to commas to separate items in a listing, when commas alone would result in confusion.

Template:Em: Template:!xt Template:Em: Template:Xt

Semicolon before "however"

The meaning of a sentence containing a trailing clause that starts with the word however depends on the punctuation preceding that word. A common error is to use the wrong punctuation, thereby changing the meaning to one not intended.

When the word however is an adverb meaning "nevertheless", it should be preceded by a semicolon and followed by a comma. Example:

Template:Xt Template:Em: Template:Xt

When the word however is a conjunction meaning "in whatever manner", or "regardless of how", it may be preceded by a comma but not by a semicolon, and should not be followed by punctuation. Example:

Template:Xt Template:Em: Template:Xt

In the first case, the clause that starts with "however" cannot be swapped with the first clause; in the second case this can be done without change of meaning:

Template:Xt Template:Em: Template:Xt

If the two clauses cannot be swapped, a semicolon is required.

A sentence or clause can also contain the word however in the middle, if it is an adverb meaning "although" that could have been placed at the beginning but does not start a new clause in mid-sentence. In this use, the word may be enclosed between commas. Example:

Template:Xt Template:Em: Template:Xt

Hyphens

Hyphens (Template:Xt) indicate conjunction. There are three main uses: Template:Multiple image

1. In hyphenated personal names (Template:Xt, Template:Xt).
2. To link prefixes with their main terms in certain constructions (Template:Xt, Template:Xt, Template:Xt).
   • A hyphen may be used to distinguish between homographs (Template:Xt means dress again, but Template:Xt means remedy or set right).
   • There is a clear trend to join both elements in all varieties of English (Template:Xt, Template:Xt). Hyphenation clarifies when the letters brought into contact are the same (Template:Xt, Template:Xt) or are vowels (Template:Xt), or where a word is uncommon (Template:Xt, Template:Xt) or may be misread (Template:Xt, not Template:!xt). Some words of these sorts are nevertheless common without the hyphen (e.g., Template:Xt is more frequently attested than Template:Xtg in contemporary English). Beware of words that change their meaning without the hyphen, e.g. Template:Xt (create again) and Template:Xt (amusement).Template:Efn
3. To link related terms in compound modifiers:Template:Efn
   • Hyphens can aid ease of reading (that is, they can be Template:Xt aids) and are particularly useful in long noun phrases: Template:Xt. But never insert a hyphen into a proper name (Template:Xt, not Template:!xt).
   • A hyphen can help to disambiguate (some Template:Xt are quite tall; Template:Xt is a program that monitors the government, whereas Template:Xt is a government program that monitors).
   • Compounds that are hyphenated when used Template:Em (adjectives before the nouns they qualify: Template:Xt, Template:Xt) or Template:Em (as a noun: Template:Xt) are usually not hyphenated when used Template:Em (descriptive phrase separated from the noun: Template:Xt, Template:Xt). Where there would otherwise be a loss of clarity, however, a hyphen may be used in the predicative form as well (Template:Xt, Template:Xt). Awkward attributive hyphenation can sometimes be avoided with a simple rewording: Template:Xt → Template:Xt.
   • Avoid using a hyphen after a standard -ly adverb (Template:Xt, Template:Xt) unless part of a larger compound (Template:Xt). In rare cases, a hyphen can improve clarity if a rewritten alternative is awkward, but rewording is usually preferable: Template:!xt can be disambiguated as Template:Xt or Template:Xt.
   • A few words ending in -ly function as both adjectives and adverbs (Template:Xt; Template:Xt). Some such dual-purpose words (like Template:Xt, Template:Xt, Template:Xt) are not standard -ly adverbs, because they are not formed by addition of -ly to an independent current-English adjective. These need careful treatment: Template:Xt, but Template:Xt; Template:Xt (no adult actors) but Template:Xt (actors without siblings).
   • A hyphen is normally used when the adverb well precedes a participle used attributively (Template:Xt; but normally Template:Xt, because well itself is modified) and even predicatively, if well is necessary to, or alters, the sense of the adjective rather than simply intensifying it (Template:Xt, Template:Xt, but Template:Xt).
   • In some cases, such as Template:Xt, the independent status of the linked elements requires an en dash instead of a hyphen. Template:Crossref
   • Use a suspended hyphen (also called a hanging hyphen) when two compound modifiers are separated (Template:Xt; Template:Xt; Template:Xt).
   • Values and units used as compound modifiers are hyphenated only where the unit is given as a whole word; when using the unit symbol, separate it from the number with a non-breaking space ( ).

Template:Em	Template:Xt (markup: 12 h shift)

Multi-word hyphenated items: It is often possible to avoid multi-word hyphenated modifiers by rewording (Template:Xt may be easier to read as Template:Xt). This is particularly important where converted units are involved (Template:Xt might be possible as Template:Xt, and the ungainly Template:!xt as simply Template:Xt).

For optional hyphenation of compound points of the compass such as southwest/south-west, see Template:Section link.

Do not use a capital letter after a hyphen except for a proper name following the hyphen: Template:Xt and Template:Xt, but not Template:!xt. In titles of published works, when given in title case, follow the capitalization rule for each part independently (Template:Xt), unless reliable sources consistently do otherwise in a particular case (Template:Xt).

Hyphenation rules in other languages may be different. Thus, in French a place name such as Template:Xt ('Three Rivers') is hyphenated, when it would not be in English. Follow reliable sources in such cases.

Spacing: A hyphen is never followed or preceded by a space, except when hanging Template:Crossref or when used to display parts of words independently, such as Template:XtTemplate:Nbspand Template:Xt.

Image filenames and redirects: Image filenames are not part of the encyclopedic content; they are tools. They are most useful if they can be readily typed, so they usually use hyphens instead of dashes. Similarly, article titles with dashes should also have a corresponding redirect from a copy of the title with hyphens: for example, Template:Xt redirects to Template:Xt.

Non-breaking: A non-breaking hyphen (Template:Tlx) will Template:Em be used as a point of line-wrap.

Soft hyphens: Use soft hyphens to mark locations where a word will be broken and hyphenated Template:Em at the end of a line of text, usually in very long words or narrow spaces (such as captions, narrow table columns, or text adjacent to a very wide image), for example: Template:Tlx. Use sparingly to avoid making wikitext difficult to read and edit. For more information, see Help:Line-break handling.

Encoding: The hyphen is represented by the ASCII/UNICODE HYPHEN-MINUS character, which is entered by the hyphen or minus key on all standard keyboards. Do not use the UNICODE HYPHEN character.

Dashes

Two forms of dash are used on Wikipedia: en dash (Template:Xt) and em dash (Template:Xt). To enter them, click on them in the CharInsert toolbar, or on a Windows keyboard enter them manually as:

• – or —
• Template:Tlx or Template:Tlx

On a Mac keyboard the en dash is entered as Template:Key press, and the em dash as Template:Key press. Do not use a double hyphen (--) to stand in for a dash. Template:Crossref

Sources use dashes in varying ways. For consistency and clarity, Wikipedia adopts the following principles.

To mark divisions within a sentence

Dashes are often used to mark divisions within a sentence: in pairs (parenthetical dashes, instead of parentheses or pairs of commas) or singly (perhaps instead of a colon). They may also indicate an abrupt stop or interruption in reporting quoted speech. In all such cases, either unspaced em dashes or spaced en dashes can be used, with consistency maintained throughout a given article:

• An em dash is unspaced on both sides:

• An en dash is spaced on both sides:

Template:Block indent Ideally, an en dash should be preceded by a non-breaking space; this prevents the dash from appearing at the beginning of a line. The Template:Tlx template may be used for this: Template:Block indent Do not insert any spaces where an en dash should be unspaced Template:Crossref.

Dashes can clarify a sentence's structure when commas, parentheses, or both are also being used.

• Template:Xt

Use dashes sparingly. More than two in a single sentence makes the structure unclear; it takes time for the reader to see which dashes form a pair, if any.

• Template:Xt
• Template:Xt
• Avoid: Template:!xt
• Better: Template:Xt

In ranges that might otherwise be expressed with to or through

For ranges between numbers, dates, or times, use an en dash:

• Template:Xt;   Template:Xt;   Template:XtTemplate:Efn

Do not change hyphens to dashes in filenames, URLs, or templates such as Template:Tlx (which formats verse ranges into URLs), even if a range is embedded in them.

Do not mix en dashes with between or from.

• Template:Xt
• Template:Xt, not Template:!xt
• Template:Xt, not Template:!xt
• Template:Xt, not Template:!xt
• Template:Xt or Template:Xt

The en dash in a range is always unspaced, except when either or both elements of the range include at least one space, hyphen, or en dash; in such cases, Template:Tl between them will provide the proper formatting.

• Template:Nobr (not Template:Nobr)
• Template:Nobr (not Template:Nobr)
• Template:Nobr (and note in this case that the second element of the range is 17, not 17Template:NbspSeptember);   Template:Nobr;   Template:Nobr
• Template:Nobr;   Template:Nobr;   Template:Nobr;   Template:Nobr (but Template:Nobr)
• Template:Xt
• Template:Nobr

If negative values are involved, an unspaced en dash might be confusing:

• Template:Xt, not Template:!xt (though Template:Xt might work in a table consistently formatted with Template:Var–Template:Var constructions)

In compounds when the connection might otherwise be expressed with to, versus, and, or between

Here, the relationship is thought of as parallel, symmetric, equal, oppositional, or at least involving Template:Em. The components may be nouns, adjectives, verbs, or any other independent part of speech. Often, if the components are reversed there would be little change of meaning.

• Template:Xt;   Template:Xt;   Template:Xt
• Template:Xt; the components are parallel and reversible; iron and cobalt retain their identity
• Wrong: Template:!xt; iron modifies roof, so use a hyphen: Template:Xt
• Wrong: Template:!xt; not separate persons, so use a hyphen: Template:Xt
• Template:Xt; red and green are separate independent colors, not mixed
• Wrong: Template:!xt; a blended, intermediate color, so use a hyphen: Template:Xt
• Template:Xt;   Template:Xt;   Template:Xt; but prefer spelling out when using words instead of numerals: Template:Xt, not with the awkward Template:!xt;  avoid confusingly reversed order: Template:!xtTemplate:Efn
• Template:Xt;   Template:Xt;   avoid using a slash (stroke) here, which indicates division
• Template:Xt;   Template:Xt;   Template:Xt;   Template:Xt;   Template:Xt
• Template:Xt;   Template:Xt;   Template:Xt;   Template:Xt
• Template:Xt;   Template:Xt

• Template:Xt;   Template:Xt

Generally, use a hyphen in compounded proper names of single entities.

• [[Guinea-Bissau|Template:Xt]]; Bissau is its capital, and this name distinguishes the country from neighboring Guinea
• Template:Xt, a single city named after two people, but Template:Xt, an area encompassing two cities
• Template:Xt, an individual named after two families

Use an en dash between the names of nations or nationalities when referring to an association between them. For people and things identifying with multiple nationalities, use a hyphen when using the combination adjectivally and a space when they are used as nouns, with the first used attributively to modify the second.

• Template:Xt;   but Template:Xt for Template:Xt
• Template:Xt;   Template:Xt
• Template:Xt;   Template:Xt
• Wrong: Template:!xt; Franco- is a Template:Em, not an independent word, so use a hyphen: Template:Xt

A slash or some other alternative may occasionally be better to express a ratio, especially in technical contexts Template:Crossref.

• Template:Xt;   Template:Xt;   Template:Xt
• Colons are often used for strictly numeric ratios, to avoid confusion with subtraction and division: Template:Xt;  Template:Xt Template:Crossref.

Use an en dash for the names of two or more entities in an attributive compound.

• Template:Xt;   Template:Xt
• Template:Xt (developed by Seeliger and Donker-Voet)
• Template:Xt or just Template:Xt (discovered by Hale and Bopp)

Do not use an en dash for hyphenated personal names, even when they are used as adjectives:

• Template:Xt with a hyphen: named after John Lennard-Jones

Do not use spaces around the en dash in any of the compounds above.

When applying a prefix or suffix to a compound that itself includes a space, hyphen, or dash

When the compound itself includes a space:

• Template:Xt (consider recasting: Template:Xt)
• Template:Xt (consider recasting: Template:Xt)
• Template:Xt
• Template:Xt
• Template:Xt

A hyphen:

• Template:Xt
• Template:Xt
• Template:Xt
• Template:Xt
• Template:Xt

A dash:

• Template:Xt
• Template:Xt

The form of category names follows the corresponding main articles, e.g., Template:Category link/core. However, the principle is not extended when compounding other words in category names, e.g., Template:Category link/core and Template:Category link/core both use hyphens.

To separate parts of an item in a list

Spaced en dashes are sometimes used between parts of list items. For example:

• Template:Xt

or

• Template:Xt
• Template:Xt
• Template:Xt

Editors may choose whether to capitalize what follows, taking into consideration the existing practice and consistency with related articles.

Other uses for en dashes

The en dash (–) has several common functions beyond its use in lists and running text. It is used to join components less strongly than a hyphen would Template:Crossref; conversely, it may also separate components less strongly than a slash would Template:Crossref. Consider the relationship that exists between two components when deciding what punctuation to place between them.

Other uses for em dashes

An indented em dash may be used when attributing the source of a passage, such as a block quotation or poem. This dash should not be fully spaced: however, for reasons related to metadata and accessibility, it is best to place a hair space between the dash and the name.Template:Efn Most of Wikipedia's quotation templates provide this formatting automatically.

For example, Template:Mxt produces:

Template:In5—Template:Hair spaceCharlotte Brontë

In article titles

In article titles, do not use a hyphen (Template:!xt) as a substitute for an en dash, for example in eye–hand span (since eye does not modify hand). Nonetheless, to aid searching and linking, provide a redirect with hyphens replacing the en dash(es), as in eye-hand span. Similarly, provide category redirects for categories containing dashes. When an en dash is being used as a separator in an article title or section heading, editors may choose whether to capitalize what follows, taking into consideration the existing practice and consistency with related articles.

Other dashes

Do not use typewriter approximations or other substitutes, such as two hyphens (Template:!xt), for em or en dashes.

For a negative sign or subtraction operator use Template:Unichar, which can also be generated by clicking on the − following the ± in the Template:Xt toolbar beneath the edit window. Do not use Template:Unichar inside a Template:Tag tag, as the character gives a syntax error; instead use a normal hyphen Template:Unichar.

Slashes

Generally, avoid joining two words with a slash (Template:Also known as forward slash, stroke, or solidus), because it suggests that the words are related without specifying how. Replace with clearer wording. In circumstances involving a distinction or disjunction, the en dash Template:Crossref is usually preferable to the slash: Template:Xt.

For example: Template:!xt

• Must both be present? → Template:Xt
• Must at least one be present? → Template:Xt
• Are they the same person? → Template:Xt

An unspaced slash may be used:

• to indicate phonemic pronunciations (Template:Xt);
• in a fraction (Template:Xt or Template:Xt), but prefer the division operator (Template:Xt) when representing elementary arithmetic in prose (Template:Xt) and a fraction bar (Template:Xt) in more advanced mathematical formulas Template:Crossref;
• to indicate regular defined yearly periods that do not coincide with calendar years (e.g., Template:Xt), if that is the convention used in reliable sources Template:Crossref;
• to express a ratio, in a form in which a slash is conventionally used (e.g., Template:Xt);

A spaced or unspaced slash may be used:

• in an expression or abbreviation widely used outside Wikipedia (e.g., Template:Xt for not applicable or Template:Xt).

A spaced slash may be used:

• to separate run-on lines in quoted poetry or song (Template:Xt);
• rarely, to mark paragraph breaks in quoted prose, where they are textually important.

To avoid awkward line breaks, code spaced slashes (and fraction slashes) with a non-breaking space on the left and a normal space on the right, as in: My mama told me / You better shop around. For short constructions, both spaces should be non-breaking: Template:Nobr. On the other hand, if two long words are connected by an unspaced slash, a Template:Tl added after the slash will allow a line break at that point.

Do not use the backslash character (Template:!xt) in place of a slash.

And/or

Avoid writing Template:!xt unless other constructions would be lengthy or awkward. Instead of Template:!xt, write simply Template:Xt (which would normally be interpreted as an inclusive or to imply or both); or, for emphasis or precision or both, write Template:Xt. Where more than two possibilities are present, instead of Template:!xt write Template:Xt or Template:Xt.

Symbols

Unicode symbols are preferred over composed ASCII symbols for improved readability and accessibility. Be mindful of presentations that may require ASCII, like sourcecode. Keys for these symbols can be found at the bottom of the Source Editor.

Symbol

Composed ASCII symbol	Preferred replacement
-->	→
<--	←
<--> or <->	↔
^	↑
>=	≥
<=	≤
~=	≈

Number (pound, hash) sign and numero

Avoid using the [[Number sign|Template:!xt]] symbol (known as the number sign, hash sign, pound sign, or octothorpe) when referring to numbers or rankings. Instead write Template:Xt, Template:Xt or Template:Xt; do not use the symbol [[Numero sign|Template:!xt]]. For example:

Template:Em Template:!xt Template:Em Template:Xt Template:Em Template:Xt Template:Em Template:Xt Template:Em Template:Xt

Exceptions:

• Issue numbers of comic books which, unlike for other periodicals, are conventionally presented in general text with the form Template:Xt, unless a volume is also given, in which case write Template:Xt or Template:Xt.
• Periodical publications carrying both, issue and number designations (typically one being a year-relative and the other an absolute value); they should be given in the form Template:Xt in citations, or be spelt out as Template:Xt in text.

When using the abbreviations, write Template:Xt, Template:Xt, Template:Xt, or Template:Xt, at first occurrence.

Terminal punctuation

• Exclamation and question marks have almost no application in encyclopedic writing.
• For the use of three periods in succession, see Template:Section link.
• In some contexts, no terminal punctuation is necessary. In such cases, the sentence often does not start with a capital letter. See Template:Section link and Template:Section link.
• Sentence fragments in captions or lists should in most cases not end with a period. See Template:Section link and Template:Section link.

Spacing

In normal text, never put a space before a comma, semicolon, colon, period/full stop, question mark, or exclamation mark (even in quoted material; see Template:Section link).

Some editors place two spaces after a period or full stop (Template:Crossref); these are condensed to one space when the page is rendered, so it does not affect what readers see.

Consecutive punctuation marks

Where a word or phrase that includes terminal punctuation ends a sentence, do not add a second terminal punctuation mark. If a quoted phrase or title ends in a question mark or exclamation mark, it may confuse readers as to the nature of the article sentence containing it, and so is usually better reworded to be mid-sentence. Where such a word or phrase occurs mid-sentence, new terminal punctuation (usually a period) must be added at the end.

Template:Em Template:!xt Template:Em: Template:Xt Template:Em: Template:Xt Template:Em Template:!xt Template:Em Template:Xt

Punctuation and footnotes

Reference tags (Template:Tag) are used to create footnotes (also called endnotes or simply notes), as citation footnotes and sometimes explanatory notes. All reference tags should immediately follow the text to which the footnote applies, with no intervening space.Template:Efn Apart from the exceptions listed below, references are placed after adjacent punctuation, not before. Adjacent reference tags should have no space between them, nor should there be any between tags and inline dispute and cleanup templates.

When reference tags are used, a footnote list must be added, and this is usually placed in the References section, near the end of the article in the standard appendices and footers.

• Example: Flightless birds have a reduced keel,Template:Dummy ref and they also have smaller wing bones than flying birds of similar size.Template:Dummy refTemplate:Dummy ref

Exceptions: Reference tags are placed before dashes, not after. If a footnote applies only to material within parentheses, the tags belong just before the closing parenthesis.

• Example: Paris is not the capital city of EnglandTemplate:Sndthe capital of which is LondonTemplate:Dummy refTemplate:Sndbut that of France.Template:Dummy ref
• Example: Kim Jong-un (Korean: ; Hanja: Template:Dummy ref) is the Supreme Leader of North Korea.Template:Dummy ref

Punctuation after formulae

Sentences should place punctuation after mathematical formulae as if they were normal body text. See Template:Section link.

Dates and time

Dates should be linked only when they are germane and topical to the subject, as discussed at Template:Section link. For ranges of dates and times, see Template:Section link.

Time of day

Times of day are normally expressed in figures rather than words. Context determines whether the 12- or the 24-hour format is more appropriate.

• Twelve-hour clock times are written in one of two forms: Template:Xt and Template:Xt, or Template:Xt and Template:Xt (wherein the spaces should be non-breaking). Use Template:Xt and Template:Xt rather than Template:!xt and Template:!xt; it may need to be specified whether midnight refers to the start or end of a date.
• Twenty-four-hour clock times are written in the form Template:Xt and Template:Xt, with no suffix. Midnight written as Template:Xt begins the day; Template:Xt ends it.

Dates

Full dates are formatted Template:Xt or Template:Xt; or where the year is omitted, use Template:Xt or Template:Xt.

• The dates in the text of any one article should all have the same format (day-first or month-first).
  • For date formats in citations, see Template:Section link.
  • Dates in quotations and titles are always left as-is.
  • If a numerical format is required (e.g., for conciseness in lists and tables), use the YYYY-MM-DD format: Template:Xt.
• Articles on topics with strong ties to a particular English-speaking country should generally use the more common date format for that country (month-first for the US, except in military usage; day-first for most others; articles related to Canada may use either consistently). Otherwise, do not change an article from one date format to the other without good reason.

Months

• For month and year, write Template:Xt, with no comma.
• Abbreviations for months, such as Template:Xt, are used only where space is extremely limited. Such abbreviations should use three letters only, and should not be followed by a period (full point) except at the end of a sentence.

Seasons

• Avoid ambiguous references to seasons, which are different in the southern and northern hemispheres.
• Names of seasons may be used when there is a logical connection to the event being described (Template:Xt) or when referring to a phase of a natural yearly cycle (Template:Xt). Otherwise, neutral wording is usually preferable (Template:Xt, not Template:!xt).
• Journals and other publications that are issued seasonally (e.g., "Summer 2005") should be dated as such in citations Template:Crossref.

Years and longer periods

• Do not use the year before the digits (Template:Xt, not Template:!xt), unless the meaning would otherwise be unclear.
• Decades are written in the format Template:Xt, with no apostrophe. Use the two-digit form ('80s) only with an established social or cultural meaning. Avoid forms such as Template:!xt that could refer to ten or a hundred years.
• Years are denoted by AD and BC or, equivalently, CE and BCE. Use only one system within an article, and do not change from one system to the other without good reason. The abbreviations are written without periods, and with a non-breaking space, as in Template:Xt. Omit AD or CE unless omitting it would cause ambiguity.

More information on all the above topics can be found at Template:Section link, including the handling of dates expressed in different calendars, and times corresponding to different time zones.

Current

Terms such as "current", "now", and "recent"Template:Efn should be avoided. What is current today may not be tomorrow; situations change over time. Instead, use date- and time-specific text. To help keep information updated use Template:Tlx, which will allow editors to catalog and update dated statements.

Template:Em Template:!xt Template:Em Template:Xt

Numbers

• Integers from zero to nine are spelled out in words. Integers greater than nine Template:Em may be expressed either in numerals or in words. Other numbers are given in numerals or in forms such as Template:Xt. See Template:Section link.
• In general, in numbers with five or more digits to the left of the decimal point, use commas to group those digits. Numbers with four digits are at the editor's discretion: Template:Xt, but either Template:Xt or Template:Xt. See Template:Section link.
• In general, use decimals rather than fractions for measurements, but fractions are sometimes used with imperial and US customary units. Keep articles internally consistent.
• Scientific notation (e.g., Template:Xt) is preferred in scientific contexts. Markup: {{val|5.8|e=7|u=kg}}.
• Write out "million" and "billion" on the first use. After that, unspaced "M" can be used for millions and "bn" for billions: Template:Xt and Template:Xt. See Template:Section link for similar words.
• Write Template:Xt, Template:Xt, or Template:Xt, but not Template:!xt (with a space) or Template:!xt. "Percent" is American usage, and "per cent" is British usage Template:Crossref. In ranges of percentages written with an en dash, write only a single percent sign: Template:Xt.
• Indicate uncertainties as e.g., Template:Xt. Markup: {{val|1.534|0.35|e=23|u=m}}. See Template:Section link for other formats.

Currencies

• Use the full abbreviation on first use (Template:Xt for the US dollar and Template:Xt for the Australian dollar), Template:Em. For example, the government of the United States always spends money in American dollars, and never in Canadian or Australian dollars.
• Use only one symbol with ranges, as in Template:Xt.
• In articles that are not specific to a country, express amounts of money in United States dollars, euros, or pounds sterling. Do not link the names or symbols of currencies that are commonly known to English-speakers (Template:Xt, Template:Xt, Template:Xt), unless there is a particular reason to do so; do not use potentially ambiguous currency symbols, unless the meaning is clear in the context.
• In country-specific articles, use the currency of the country. On first occurrence, consider including conversion to US dollars, euros, or pounds sterling, at a rate appropriate to the context. For example, Template:Xt. Wording such as "approx." is not appropriate for simple rounding-off of the converted amount.
• Generally, use the full name of a currency, and link it on its first appearance if English-speakers are likely to be unfamiliar with it (Template:Xt); subsequent occurrences can use the currency sign (just Template:Xt).
• Most currency symbols are placed Template:Em the number, and unspaced Template:Nobr

Units of measurement

• The main unit in which a quantity is expressed should generally be an SI unit or non-SI unit officially accepted for use with the SI. However,
  • Scientific articles may also use specialist units appropriate for the branch of science in question.
  • In non-scientific articles with strong ties to the United States, the main unit is generally a US customary unit (Template:Xt).
  • In non-scientific articles with strong ties to the United Kingdom, although the main unit is generally a metric unit (Template:Xt), imperial units are still used as the main units in some contexts (Template:Xt).
• Where English-speaking countries use different units for the same measurement, provide a conversion in parentheses. Examples: Template:Xt; Template:Xt. See Template:Tlx.
• In a direct quotation, always retain the source's units. Any conversion should follow in square brackets (or, an obscure use of units can be explained in the article text or a footnote).
• Where space is limited (such as tables, infoboxes, parenthetical notes, and mathematical formulas) unit symbols are preferred. In prose, unit names should be given in full if used only a few times but symbols may be used when a unit (especially one with a long name) is used repeatedly after spelling out the first use (e.g., Template:Xt), except for unit names that are hardly ever spelled out (Template:Xt rather than Template:!xt).
• Most unit names are not capitalized (see Template:Section link for spelling differences).
• Use "per" when writing out a unit, rather than a slash: Template:Xt, not Template:!xt.
• Units unfamiliar to general readers should be presented as a name–symbol pair on first use, linking the unit name (Template:Xt).
• For ranges, see Template:Section link, and MOS:NUM, at Template:Section link.
• Unit symbols are preceded by figures, not by spelled-out numbers. Values and unit symbols are separated by a non-breaking space. For example, Template:Xt. The percent sign and units of degrees, minutes, and seconds Template:Em are unspaced.

Common mathematical symbols

• For a negative sign or subtraction operator, use a minus sign (Template:Xt, Unicode character U+2212 MINUS SIGN). Input by clicking on it in the insert box beneath the edit window or by typing −.
• For multiplication, use a multiplication sign (Template:Unichar) or a dot (Template:Unichar), which are input by clicking on them in the edit toolbox under the edit window or by entering × or ⋅. Care should be taken not to confuse the dot operator (in the "Math and logic" section of the edit toolbox) with an interpunct (in the "Insert" section of the edit toolbox) or a bullet. The letter Template:Xt should not be used to indicate multiplication, but it is used (unspaced) as the substitute for "by" in terms such as Template:Xt.
• Exponentiation is indicated by a superscript, Template:Xt (typed as ''a''<sup>''n''</sup>.
• Do not use programming language notation outside computer program text. In most programming languages, subtraction, multiplication, and exponentiation are represented by the hyphen-minus -, the asterisk *, and either the caret ^ or the double asterisk ** respectively; scientific notation is replaced by E notation.
• Symbols for binary operators and relations are usually spaced on both sides:
  • plus, minus, and plus-or-minus (as binary operators): Template:Xt, Template:Xt, Template:Xt (as in Template:Xt);
  • multiplication and division: Template:Xt, Template:Xt;
  • equals, does not equal, equals approximately: Template:Xt, Template:Xt, Template:Xt;
  • is less than, is less than or equal to, is greater than, is greater than or equal to: Template:Xt, Template:Xt, Template:Xt, Template:Xt.
• Symbols for unary operators are closed-up to their operand:
  • positive, negative, and positive-or-negative signs: Template:Xt, Template:Xt, Template:Xt (as in Template:Xt);
  • other unary operators, such as the exclamation mark as a factorial sign (as in Template:Xt).
• Variables are italicized, but digits and punctuation are not; only x and y are italicized in Template:Xt.
• Template:Tlx can be used to style formulas to distinguish them from surrounding text. For single variables, Template:Tlx is handy.

Grammar and usage

Possessives

Singular nouns

For the possessive of singular nouns, including proper names and words ending in s, add 's (Template:Xt, Template:Xt, Template:Xt, Template:Xt, Template:Xt, Template:Xt, Template:Xt, Template:Xt). Exception: abstract nouns ending with an /s/ sound when followed by sake (Template:Xt, Template:Xt). If a name ending in s or z would be difficult to pronounce with 's added, consider rewording (Template:Xt becomes Template:Xt).

Plural nouns

For a normal plural noun ending with a pronounced s, form the possessive by adding just an apostrophe (Template:Xt, Template:Xt). For a plural noun Template:Em ending with a pronounced s, add 's (Template:Xt, Template:Xt, Template:Xt; Template:Xt, but where rewording is an option, this may be better: Template:Xt).

Official names

Official names (of companies, organizations, or places) should not be altered. (Template:Xt should therefore Template:Em be rendered as Template:!xt or Template:!xt, even for consistency.)

Usage

A possessive construction must immediately be followed by what is possessed. For example:

• Template:Xt, not Template:!xt
• Template:Xt, not Template:!xt
• Template:Xt, not Template:!xt

Pronouns

First-person pronouns

To maintain an objective and impersonal encyclopedic voice, an article should never refer to its editors or readers using I, my, we, us, our, or similar words: Template:!xt. But some of these words are acceptable in certain figurative uses. For example:

• In historical articles to mean the modern world as a whole: Template:Xt
• The author's we found in scientific writing (Template:Xt), though passive voice may be preferable (Template:Xt).Template:Efn

Second-person pronouns

Avoid addressing the reader using you or your, which sets an inappropriate tone Template:Crossref.

• Use a noun or a third-person pronoun: instead of Template:!xt, use Template:Xt, or Template:Xt.
• If a person cannot be specified, or when implying "anyone" as a subject, the impersonal pronoun one may be used: Template:Xt. Other constructions may be preferable if the pronoun one seems stilted: Template:Xt.
• The passive voice may sometimes be used instead:Template:Efn Template:Xt.
• Do not bait links, e.g., "Template:!xt"; let the browser's normal highlighting invite a click. ("Template:!xt" also makes no sense to someone reading on paper.)
• Likewise, "See: ..." or "Consider ..." (in reference to arguments, principles, facts, etc.) are milder second-person baits, common in academic writing (pedagogy). This interactive personality is inconsistent with an encyclopedia's passive presentation of objective matter.
  • "See" and the like can be used to internally cross-reference other Wikipedia material. Do not italicize words like "see". Such a cross-reference should be parenthetical, so the article text stands alone if the parenthetical is removed. Template:Tlx can be used for this: Template:Tlx, Template:Tlx It is usually better to rewrite the material to integrate these links contextually rather than use explicit Wikipedia self-references.
• Do not address the reader with the Socratic method by asking and answering questions. Template:!xt

Third-person pronouns

Refer to a person with pronouns (and other gendered words) that reflect their latest self-identification in recent reliable sources. Singular they/them/their are appropriate in reference to anyone who uses those, as replacements for neopronouns, and in generic reference to persons of unknown gender. Template:Crossref

Ships (military or private-sector) may be referred to by either neuter pronouns (it, its) or feminine pronouns (she, her). Both usages are acceptable, but each article should be internally consistent and exclusively employ only one style.Template:Efn As with all optional styles, articles should not be changed from one style to another without clear and substantial reason.Template:Efn Try to avoid close, successive uses of the same referent for a ship, by using different referents in rotation; for example, it or she, the ship, and the ship's name. The she/her optional style does not apply to other vessel/vehicle types, such as trains.Template:Efn Template:Crossreference

Plurals

Words adopted into English take the plurals shown in appropriate English dictionaries, otherwise we follow the pluralization conventions of the native language.

Some collective nounsTemplate:Sndsuch as team (and proper names of them), army, company, crowd, fleet, government, majority, mess, number, pack, and partyTemplate:Sndmay refer either to a single entity or to the members that compose it. In British English, such words are sometimes treated as singular, but more often treated as plural, according to context (but singular is not actually Template:Em). In North American English, these words are almost invariably treated as singular; the major exception is that when a sports team is referred to by its short name, plural verbs are commonly used, e.g. Template:Xt.

Names of towns and countries usually take singular verbs (even when grammatically plural: Template:Xt, Template:Xt), but exceptionally in British English, typically when used to refer to a sports team named after a town or country or when discussing actions of a government, plural is used. For example, in Template:Xt, England refers to a football team; but in Template:Xt, it refers to the country. See also Template:Section link including Template:Section link.

Verb tense

By default, write articles in the present tense, including those covering works of fiction Template:Crossref and products or works that have been discontinued. Generally, use past tense only for past events, and for subjects that are dead or no longer meaningfully exist, such as deceased people or defunct companies. Use past tense for articles about periodicals no longer produced, with common-sense exceptions.

• Template:Xt
• Template:Xt
• Template:Xt
• Template:Xt
• Template:Xt (not Template:!xt).
• Template:Xt
• Template:Xt (not Template:!xt).
• Template:Xt (not Template:!xt).

Tense can be used to distinguish between current and former status of a subject: Template:Xt (Emphasis added to distinguish the different tense usages; Dún Aonghasa is a structure that was later damaged by an event.)

Always use present tense for verbs that describe genres, types, and classes, even if the subject of the description (e.g. program, library, device) no longer exists, is discontinued, is unsupported or is unmaintained. Present tense is also used for discontinued television shows.

Vocabulary

Contractions

Avoid contractions, which have little place in formal writing. For example, write Template:Xt instead of Template:!xt. Use of Template:Xt is an exception. Contracted titles such as Template:!xt and Template:!xt generally should not be used but may apply in some contexts (e.g., quoted material, place names, titles of works).

Gender-neutral language

Template:For-multi Use gender-neutral language – avoiding the generic he, for example – if this can be done with clarity and precision. This does not apply to direct quotations or the titles of works (Template:Xt), which should not be altered, or to wording about one-gender contexts, such as an all-female school (Template:Xt).

References to space programs, past, present and future, should use gender-neutral phrasing: Template:Xt, Template:Xt, Template:Xt, Template:Xt, Template:Xt, Template:Xt, Template:Xt, Template:Xt, not Template:!xt or Template:!xt. Direct quotations and proper nouns that use gendered words should not be changed, like Template:Xt.

Contested vocabulary

Avoid words and phrases that give the impression of straining for formality, that are unnecessarily regional, or that are not widely accepted. See also Template:Section link.

Instructional and presumptuous language

Avoid phrases such as Template:!xt and Template:!xt, which address readers directly in an unencyclopedic tone and lean toward instructional. They are a subtle form of Wikipedia self-reference, "breaking the fourth wall". Similarly, phrases such as Template:!xt, Template:!xt, Template:!xt, Template:!xt, and Template:!xt make presumptions about readers' knowledge, may express a viewpoint, and may call into question the reason for including the information in the first place.

Do not Template:Em readers that something is interesting, ironic, surprising, unexpected, amusing, curious, coincidental, etc. Simply present sourced facts neutrally and let readers draw their own conclusions. Such constructions can usually just be deleted, leaving behind proper sentences with a more academic and less pushy tone: Template:!xt becomes Template:Xt Similar variants which indirectly instruct readers, such as Template:!xt or Template:!xt, may be rewritten by leaving out those words: Template:!xt becomes just Template:Xt.

Avoid rhetorical questions, especially in headings. Use a heading of Template:Xt and text such as Template:Xt, not Template:!xt

For issues in the use of cross-referencesTemplate:Snde.g., Template:XtTemplate:Sndsee Template:Sectionlink.

Subset terms

A subset term identifies a set of members of a larger class. Common subset terms are including, among, and etc. Avoid redundant subset terms (e.g., mis-constructions like Template:!xt or Template:!xt). The word including does not introduce a complete list; instead, use consisting of, or composed of.

Identity

When there is a discrepancy between the term most commonly used by reliable sources for a person or group and the term that person or group uses for themselves, use the term that is most commonly used by recentTemplate:Efn reliable sources. If it is unclear which is most used, use the term that the person or group uses.

Disputes over how to refer to a person or group are addressed by Wikipedia content policies, such as those on verifiability, and neutral point of view (and article titles when the term appears in the title of an article).

Use specific terminology. For example, it is often more appropriate for people or things from Ethiopia (a country in Africa) to be described as Ethiopian, not carelessly (with the risk of stereotyping) as African.

Gender identity

Specific guidelines apply to any person whose gender might be questioned, and any living transgender or non-binary person. In summary:

• Use gendered words only if they reflect the person's latest self-identification as reported in recent sources.
• If the person is living and was not notable yet when a former name was in use, that name should not be included in any Wikipedia page, even in quotations, as a privacy matter. Exception: Any name that appears in a source citation (whether as an author or mentioned in a work title) must be included exactly as it appeared in the source. Do not expunge or replace such names.
• Former names under which a living person was notable should be introduced with "born" or "formerly" in the lead sentence of their main biographical article. Name and gender matters should be explained at first appearance in that article, without overemphasis. In articles on works or other activities of such a person, use their current name by default, and give another name associated with that context in a parenthetical or footnote, only if they were notable under that name. In other articles, do not go into detail about such a person's name or gender except when directly relevant to the context.
• Avoid confusing constructions by rewriting. Paraphrase, elide, or use square brackets to replace portions of quotations as needed to avoid confusion, former names, and mismatching gendered words.

Non-English terms

Terms without common usage in English

Non-English terms should be used sparingly. In general, use italics for phrases and words that are not current in English. This is best done with the Template:Tlx template using the appropriate ISO language code, e.g., Template:Tlx. There are alternatives to the Template:Tnull template which also provide additional information about a non-English word or phrase, such as a link to the language name; Template:Crossref. As Wikipedia does not apply italics to names of people, places, or organizations, the alternative template Template:Tlx can be used to apply the language markup without italicizing.Template:Efn Templates like Template:Tlx automatically italicize text written using the Latin alphabet, so specifying italics is unnecessary.

Text written in non-Latin scripts such as Greek, Cyrillic, and Chinese should not be italicized or put in bold, as the difference in script is already sufficient to visually distinguish the text. Generally, any non-Latin text should be accompanied by an appropriate romanization.

Terms with common usage in English

Loanwords and borrowed phrases that have common usage in EnglishTemplate:SndTemplate:Xt, Template:Xt, Template:XtTemplate:Snddo not require italics. A rule of thumb is to not italicize words that appear unitalicized in major general-purpose English dictionaries.

Spelling and romanization

Names and terms originally written using a non-Latin script—such as the Greek alphabet, the Cyrillic alphabet, or Chinese characters—must be romanized for English-language use. If a particular romanization of the subject's name is most common in English (Template:Xt, Template:Xt), that form should be used. Otherwise, the romanization of names should adhere to a particular widely used system for the language in question (Template:Xt, Template:Xt).

The use of diacritics in non-English words is neither encouraged nor discouraged. Use generally depends on whether they appear in reliable English-language sources, though with some additional constraints imposed by site guidelines. Provide redirects from alternative forms that include or exclude diacritics.

Proper names in languages written using the Latin alphabet can include letters with diacritics, ligatures, and other characters that are not commonly used in contemporary English. Wikipedia normally retains these special characters, except where there is a well-established English spelling that replaces them with English standard letters. Examples:

• The name of the article on Hungarian mathematician Paul Erdős is spelt with the double acute accent, and the alternative spellings Paul Erdos and Paul Erdös redirect to that article.
• Similarly, the name of the article on the Nordic god Template:Langr is so spelt, with redirects from the ligature-free form Template:Langr and the Swedish spelling Template:Langr.
• However, the region of Spain named in Spanish and in Catalan is given as Aragon, without the accent, as this is the established English name. Non-English forms with diacritics appear in the article's lead section.

Use of diacritics is determined on a topic-by-topic basis; a small group of editors cannot prohibit or require the use of diacritics within a given class of articles.Template:Efn

Spell a name consistently in the title and the text of an article. Template:Crossref For a non-English name, phrase, or word, adopt the spelling most commonly used in English-language reliable sources, including but not limited to those already cited in the article.Template:Efn For punctuation of compounded forms, see relevant guidelines in Template:Section link.

Proper names in non-English languages should generally not be italicized, unless another reason applies; such as with titles of major published works, e.g., [[Les Liaisons dangereuses|Template:Xt]]; or when being compared to other names for the same subject in a words-as-words manner, e.g., Template:Xt. When non-English text should not be italicized, it can still be properly tagged by using the Template:Tlx template with the Template:Para parameter: Template:Tlx.

Sometimes usage will be influenced by other guidelines, such as Template:Section link, which may lead to different choices in different articles.

• For handling of quotations in languages other than English, see Template:Section link.
• For non-English characters that resemble single quotation marks and apostrophes, see Template:Section link.

• For the capitalization in the titles of non-English language works, see Template:Section link.
• For linear and interlinear glosses and their particular uses of small-caps (and italics and single quotes), see Template:Section link.

Technical language

Some topics are necessarily technical; however, editors should seek to write articles accessible to the greatest possible number of readers. Minimize the use of jargon, and adequately explain its meaning when it is used. Overly technical material can be tagged with Template:Tlx or Template:Tlx, so that it can be addressed by other editors. For topics that require a more technical approach, the creation of a separate introductory article (like Introduction to general relativity) may be a solution.

Excessive wikilinking (linking within Wikipedia) can result from trying too hard to avoid putting explanations in parenthetical statements, like the one that appeared earlier in this sentence. Do not introduce specialized words solely to teach them to the reader when more widely understood alternatives will do.

When the concepts underlying the jargon used in an article are too complex to explain concisely in a parenthetical, write one level down. For example, consider adding a brief background section with Template:Tlx tags pointing to articles with a fuller treatment of the prerequisite material. This approach is practical only when the prerequisite concepts are central to the exposition of the article's main topic and when such prerequisites are not too numerous. Short articles, such as stubs, generally do not have such sections.

Geographical items

Geographical or place names are the nouns used to refer to specific places and geographic features. These names often give rise to conflict, because the same places are called different things by different peoples speaking different languages. Many place names have a historical context that should be preserved, but common sense should prevail. There can be few places that have not been parts of more than one culture or have had only one name. As proper nouns, all such place names (but not terms for types of places) have major words capitalized.

A place should generally be referred to consistently by the same name as in the title of its article Template:Crossref. An exception may be made when there is a widely accepted historical English name appropriate to the given context. In cases where such a historical name is used, it should be followed by the modernTemplate:Efn name in round brackets (parentheses) on the first occurrence of the name in applicable sections of the article. As with linking, this should not be done to the detriment of style. On the other hand, it is probably better to provide such a variant too often than too rarely. If more than one historical name is applicable for a given context, the other names should be added after the modern English name, that is: "<historical name> (<modern name>, <other historical names>)".

This is an English-language encyclopedia, so established English names are preferred if they exist, and spellings in non-English alphabets should always be transcribed into the Roman alphabet. In general, other articles should refer to places by the names which are used in the articles on those places, according to the rules described at Wikipedia:Naming conventions (geographic names). If a different name is appropriate in a given historical or other context, then that may be used instead, although it is normal to follow the first occurrence of such a name with the standard modern name in parentheses.

At the start of an article, provide notable equivalent names from other languages, including transcriptions where necessary:

Cologne (Template:Langx, IPA: ) is the ...

is the ...

Names in languages with no particular present-day or historical ties to the place in question (English excepted, of course) should Template:Em be listed as alternatives.

Avoid anachronism. An article about Junípero Serra should say he lived in Alta Mexico, not in California, because the latter entity did not yet exist in Serra's time. The Romans invaded Gaul, not France, and Thabo Mbeki was the president of the Republic of South Africa, not of the Cape Colony. For clarity, consider also mentioning the current name of the area (for example, "in what is now France"), especially if no English name exists for that area in the relevant historical period.

Media files

• Each media file (image, video, or audio) should be inside the levelTemplate:Nbs2 section to which it relates or at the top of the lead section. Do not place files immediately above section headings.
• Avoid sandwiching text horizontally between two files that face each other, between a file and an infobox, or similar configuration.
• It is often preferable to place images of people so they face the text of the article. Do not achieve this by reversing the image, as this can create a false presentation e.g., by reversing the location of scars or other features.
• Any galleries should comply with Template:Section link. Consider linking to additional files on Commons instead.
• Do not refer to files as being to the left, the right, above, or below, because image placement varies with platform and is meaningless to people using screen readers; instead, use captions to identify images.
• A file's Template:Para text takes the file's place for those who are unable to see it. See Wikipedia:Manual of Style/Accessibility/Alternative text for images.

Using images to display text

Textual information should always be transmitted as text, rather than in an image, so that it can be easily searched, selected, copied, and manipulated by readers. These tasks are generally difficult or impossible with text presented in an image: images are slower to download and generally cannot be searched or processed by screen readers used by the visually impaired. Any important textual information in an image should be provided somewhere as text, generally either in the image's caption or alt text. However, its presentation can also be adjusted using CSS.

For entering textual information as audio, see Wikipedia:WikiProject Spoken Wikipedia.

Captions

Media files should have captions, unless they are unambiguous depictions of the subject of the article or are "self-captioning" (such as reproductions of album or book covers). In biography articles, a caption is not necessary for a portrait of the subject pictured alone, but one might be used to give the year, the subject's age or name, or other circumstances of the portrait.

• Captions normally start with a capital letter.Template:Efn
• Most captions are not complete sentences but merely sentence fragments which should not end with a period. However, if any complete sentence occurs in a caption, then every sentence and every sentence fragment in that caption should end with a period.
• The text of captions should not be specially formatted, except in ways that would apply if it occurred in the main text (e.g., italics for the Latin name of a species).
• Captions should be succinct; more information can be included on its description page or in the main text. However, captions for technical charts and diagrams may need to be substantially longer than usual; they should fully describe all elements of the image and indicate its significance.

Bulleted and numbered lists

• Do not use lists if a passage is read easily as plain paragraphs.
• Use proper wiki markup- or template-based list code Template:Crossref.
• Do not leave blank lines between items in a bulleted or numbered list unless there is a reason to do so, since this causes the Wiki software to interpret each item as beginning a new list.
  • Indents (such as this) are permitted if the elements are "child" items.
• Use numbers rather than bullets only if:
  • a need to refer to the elements by number may arise;
  • the sequence of the items is critical; or
  • the numbering has some independent meaning, for example in a listing of musical tracks.
• Use the same grammatical form for all elements in a list, and do not mix sentences and sentence fragments as elements, for example when the elements are:
  • complete sentences – each one is formatted with sentence case (its first letter is capitalized) and a final period (full point);
  • sentence fragments – the list is typically introduced by an introductory fragment ending with a colon;
  • titles of works – they retain the original capitalization of the titles;
  • other elements – they are formatted consistently in either sentence case or lower case.

Links

Wikilinks

Make links only where they are relevant and helpful in the context. Excessive use of hyperlinks can be distracting and may slow the reader down. Redundant links (like the one in Template:!xt) clutter the page and make future maintenance harder. High-value links that Template:Em worth pursuing should stand out clearly.

Linking to sections: A hash sign (#) followed by the appropriate heading will lead to a relevant part of a page. For example, [[Apostrophe#Use in non-English names]] links to a particular section of the article Apostrophe.

Initial capitalization: Wikipedia's MediaWiki software does not require that wikilinks begin with an upper-case character. Capitalize the first letter only where this is naturally called for, or when specifically referring to the linked article by its name (see also related rule for italics in cross-references): Template:Xt

Check links: Ensure the destination is the intended one; many dictionary words lead to disambiguation pages and not to complete or well-chosen articles.

External links

External links should not normally be used in the body of an article. Instead, articles can include an External links section at the end, pointing to further information outside Wikipedia as distinct from citing sources. The standard format is a primary heading, == External links ==, followed by a bulleted list of links. Identify the link and briefly indicate its relevance to the article. For example:

These will appear as:

Where appropriate, use external link templates such as Template:Tlx and Template:Tlx.

Add external links with discretion; Wikipedia is not a link repository.

Miscellaneous

Keep markup simple

Other things being equal, keep markup simple. This makes wikitext easier to understand and edit, and the results seen by the reader more predictable. Use HTML and CSS markup sparingly. See: KISS principle.

In general, wikitext formatting is considered easier to use than HTML and wikitext is preferred if there are equivalents; see Help:HTML in wikitext. Obsolete elements and attributes should be updated or removed. There are many templates that allow HTML markup to be used without putting it in articles directly, such as Template:Tl (see MOS:EMPHASIS) and Template:Tl (see MOS:BOLD).

An HTML character entity is sometimes better than the equivalent Unicode character, which may be difficult to identify in edit mode; for example, Α is explicit whereas Α (the upper-case form of Greek α) may be misidentified as the Latin A.

Formatting issues

Modifications in font size, blank space, and color Template:Crossref are an issue for the Wikipedia site-wide style sheet and should be reserved for special cases only.

Typically, the use of custom font styles:

• reduces consistency, as the text no longer looks uniform;
• reduces usability, as it may be impossible for people with custom style sheets (e.g. for accessibility reasons) to override it, and may clash with a different skin or inconvenience people with color blindness Template:Crossref; and
• causes disputes, as other editors may disagree aesthetically with the choice of style.

Specify font sizes Template:Em (for example with font-size: 85%) rather than Template:Em (like font-size: 8pt). The resulting font size of any text should not drop below 85% of the page's default font size.

Color coding

Do not use color Template:Em to mark differences in text: they may be invisible to people with color blindness and useless in black-and-white printouts or displays.

Choose colors such as maroon and teal that are distinguishable by readers with the most common form of colorblindness, and Template:Em mark the differences with change of font or some other means (maroon and alternative font face, teal). Avoid low contrast between text and background colors. See also color coding.

Even for readers with unimpaired color vision, excessive background shading of table entries impedes readability and recognition of Wikilinks. Background color should be used only as a Template:Em visual cue and should be subtle (consider using lighter, less-dominant pastel hues) rather than glaring.

Indentation

Do not use quotation templates to indent non-quotations. Various templates are available for indentation, including Template:Tlx to indent an entire block and Template:Tlx to indent inline.

Do not use : (description list markup) to indent text in articles, even though it is common on talk pages. It causes accessibility problems and outputs invalid HTML. Template:Crossref

To display a mathematical formula in its own indented paragraph, use Template:Tag. See Help:Displaying a formula#Block for more details.

Controlling line breaks

It is sometimes desirable to force a text segment to appear entirely on a single lineTemplate:Mdashbthat is, to prevent a line break (line wrap) from occurring anywhere within it.

• A non-breaking space (or hard space) will never be used as a line-break point. Markup: for Template:Xt, code 19 kg Template:Em 19{{nbsp}}kg.
• Or use Template:Tlx, Template:Tlx, or Template:Tlx (all equivalent). Markup: for Template:Xt, code Template:Tlx.

It is desirable to prevent line breaks where breaking across lines might be confusing or awkward. For example: Template:Columns list

Whether a non-breaking space is appropriate depends on context: whereas it is appropriate to use 12{{nbsp}}MB in prose, it may be counterproductive in a table (where an unattractive break may be acceptable to conserve precious horizontal space) and unnecessary in a short parameter value in an infobox (where a break would never occur anyway).

A line break may occur at a thin space ( , or Template:Tlx), which is sometimes used to correct too-close placement of adjacent characters. An undesirable line break may also occur at special characters such as in bit/s. To prevent these, consider using Template:Tlx e.g. Template:Tlx.

Insert non-breaking and thin spaces as named character reference (  or  ), or as templates that generate these (Template:Tlx, Template:Tlx), and never by entering them directly into the edit window from the keyboardTemplate:Sndthey are visually indistinguishable from regular spaces, and later editors will be unable to see what they are. Inside wikilinks, a construction such as Template:Nobr works but Template:Nobr doesn't.

Scrolling lists and collapsible content

Elements that can selectively display or hide content can interfere with the ability of readers to access said content. These mechanisms include scrolling lists, and templates like Template:Tlx that can be toggled between collapsed and uncollapsed states using a [Template:Resize] button. These mechanisms should not be used to conceal "spoiler" information. Templates should generally not be used to store relevant article text, as it interferes with editors' ability to find and edit it. Moreover, content in an article should not be collapsed by default. This applies equally to content in footnotes, tables, and embedded lists, image galleries, and image captions.

If such mechanisms are used, care must be taken to ensure the content remains accessible for all users, including those with limited CSS or JavaScript support. When collapsing is desired, it must be done using the collapsible parameter of relevant templates, or certain manually added CSS classes (see Help:Collapsing). Other methods of hiding content should not be used, as they may render content inaccessible to many users, such as those browsing Wikipedia with JavaScript disabled or using proxy services.

Collapsed or auto-collapsing cells or sections may be used with tables if they simply repeat information covered in the main text (or are purely supplementary, e.g., several past years of statistics in collapsed tables for comparison with a table of uncollapsed current stats). Auto-collapsing is often a feature of navboxes. A few infoboxes also use pre-collapsed sections for infrequently accessed details. If information in a list, infobox, or other non-navigational content seems extraneous or trivial enough to inspire pre-collapsing it, consider raising a discussion on the article (or template) talk page about whether it should be included at all. If the information is important and the concern is article density or length, consider dividing the article into more sections, integrating unnecessarily list-formatted information into the article prose, or splitting the article.

Invisible comments

Editors use "invisible" commentsTemplate:Sndnot shown in the rendered page seen by readers of the article, but visible when an editor opens the article for editingTemplate:Sndto communicate with one another.

Invisible comments are useful for alerting other editors to issues such as common mistakes that regularly occur in the article, a section title being the target of an incoming link, or pointing to a discussion that established a consensus relating to the article. They should not be used to instruct other editors not to perform certain edits, as this could be perceived as expressing a form of ownership over an article. However, where existing local consensus is against making an edit, invisible comments may help draw an editor's attention to that consensus.

Do not add too many invisible comments, as they can clutter the wiki source for other editors. Ensure that your invisible comment does not change the formatting, for example by introducing unwanted white space in the rendered page.

How to add an invisible comment

Manually you can enclose the text you intend to be read only by editors between <!-- and -->. For example:

• Template:Example HTML comment (there are bots which can do this, see MOS:RENAMESECTION, preferably Template:Tlxs should be used to prevent this problem.)
• Template:Example HTML comment

The VisualEditor toolbar (not the source editor toolbar) can also be used:

• Click the "Insert" dropdown plus signTemplate:Nbspdown arrow
• Select speech bubbleTemplate:Nbsp"Invisible comment". (You may have to press down arrowTemplate:Nbsp"More").

This will produce <!-- Invisible comment -->, or if text is selected it will nest the text between <!-- and -->.

Pronunciation

Pronunciation in Wikipedia is indicated in the International Phonetic Alphabet (IPA). In most situations, for ease of understanding by the majority of readers and across variants of the language, quite broad IPA transcriptions are best for English pronunciations. See Help:IPA/English and Help:IPA (general) for keys, and Template:Tlx for templates that link to these keys. For English pronunciations, pronunciation respellings may be used Template:Em the IPA.
