The '''Latin alphabet''' comprises the letters originally used by the [[Ancient Rome|ancient Romans]] to write the [[Latin language]]. Largely unaltered except for a couple of letters splitting:({{angbr|[[J]]}} from {{angbr|I}} and {{angbr|[[U]]}} from {{angbr|V}}), an addition ({{angbr|[[W]]}}), and extensions (such as letters with [[diacritic]]s), it forms the [[Latin script]] that is used to write many languages worldwide: in [[Languages of Europe|western and central Europe]], in [[languages of Africa|Africa]], in [[languages of the Americas|the Americas]], and in [[languages of Oceania|Oceania]].

Its basic modern 26-letter inventory is standardized as the [[ISO basic Latin alphabet]].

==Etymology==
The term ''Latin alphabet'' may refer to either the alphabet used to write Latin (as described in this article) or other alphabets based on the [[Latin script]], which is the basic set of letters common to the various alphabets descended from the classical Latin alphabet, such as the [[English alphabet]]. These [[Latin-script alphabet]]s may discard letters, like the [[Rotokas alphabet]], or add new letters, like the [[Danish orthography|Danish]] and [[Norwegian orthography|Norwegian]] alphabets. [[Letter (alphabet)|Letter]] shapes have evolved over the centuries, including the development in [[Medieval Latin]] of [[lower-case]], forms which did not exist in the Classical period alphabet.

== Evolution ==
{{broader| History of the alphabet}}
The Latin alphabet evolved from the visually similar [[Etruscan alphabet]], which evolved from the [[Cumae alphabet|Cumaean Greek version]] of the [[Greek alphabet]], which was itself descended from the [[Phoenician alphabet]], which in turn derived from [[Egyptian hieroglyphs]].<ref>{{cite book |author-first1=Michael C. |author-last1=Howard |date=2012 |page=[https://books.google.com/books?id=6QPWXrCCzBIC&pg=PA23 23] |title=Transnationalism in Ancient and Medieval Societies |isbn=978-0-7864-6803-4 |publisher=McFarland & Company}}</ref> The [[History of Rome#Etruscan dominance|Etruscans ruled early Rome]]; their alphabet evolved in Rome over successive centuries to produce the Latin alphabet.
During the [[Middle Ages]], the Latin alphabet was used (sometimes with modifications) for writing [[Romance languages]], which are direct descendants of [[Latin]], as well as for writing [[Celtic languages|Celtic]], [[Germanic languages|Germanic]], [[Baltic languages|Baltic]] and some [[Slavic languages]]. With the [[First wave of European colonization|age of colonialism]] and [[Christian evangelism]], the [[Latin script]] spread beyond [[Europe]], coming into use for writing indigenous [[Indigenous languages of the Americas|American]], [[Australian Aboriginal languages|Australian]], [[Austronesian languages|Austronesian]], [[Austroasiatic languages|Austroasiatic]] and [[Languages of Africa|African languages]]. More recently, [[linguistics|linguists]] have also tended to prefer the Latin script or the [[International Phonetic Alphabet]] (itself largely based on the Latin script) when transcribing or creating written standards for non-European languages, such as the [[African reference alphabet]].

===Signs and abbreviations===
Although Latin did not use diacritical marks, apart from the [[Apex (diacritic)|apex]] and [[sicilicus]], signs of truncation of words (often placed above or at the end of the truncated word) were very common. Furthermore, abbreviations or smaller overlapping letters were often used. This meant that if the text was engraved on stone, the number of letters to be engraved was reduced, while if it was written on paper or parchment, it saved precious space. This custom continued in the Middle Ages: hundreds of symbols and abbreviations exist, varying from century to century.<ref>{{cite book|last1=Cappelli|first1=Adriano|title=Dizionario di Abbreviature Latine ed Italiane|date=1990|publisher=Editore Ulrico Hoepli|location=Milano|isbn=88-203-1100-3}}</ref>

==History==
{{Main|History of the Latin script}}

===Origins===
<!--keep clear structure, please -->
It is generally believed that the Latin alphabet used by the [[Ancient Rome|Romans]] was derived from the [[Old Italic alphabet#Etruscan alphabet|Old Italic alphabet]] used by the [[Etruscan civilization|Etruscans]]. That alphabet was derived from the [[Archaic Greek alphabets#Euboean|Euboean alphabet]] used by the [[Cumae]], which in turn was derived from the [[Phoenician alphabet]].<ref>{{Cite web |title=Etruscan alphabet {{!}} Etruscan Writing, Ancient Scripts & Language {{!}} Britannica |url=https://www.britannica.com/topic/Etruscan-alphabet |access-date=2025-03-21 |website=www.britannica.com |language=en}}</ref>

====Old Latin alphabet====
Latin included 21 different characters. The letter {{angle bracket|C}} was the western form of the Greek [[gamma]], but it was used for the sounds {{IPA|/ɡ/}} and {{IPA|/k/}} alike, possibly under the influence of [[Etruscan language|Etruscan]], which might have lacked any voiced [[plosives]]. Later, probably during the 3rd century BC, the letter {{angle bracket|Z}} – not needed to write Latin properly – was replaced with the new letter {{angle bracket|G}}, a {{angle bracket|C}} modified with a small vertical stroke, which took its place in the alphabet. From then on, {{angle bracket|G}} represented the [[Voice (phonetics)|voiced]] plosive {{IPA|/ɡ/}}, while {{angle bracket|C}} was generally reserved for the voiceless plosive {{IPA|/k/}}. The letter {{angle bracket|K}} was used only rarely, in a small number of words such as ''[[Kalends|Kalendae]]'', often interchangeably with {{angle bracket|C}}.

====Classical Latin alphabet====
After the [[Roman conquest of Greece]] in the 1st century BC, Latin adopted the Greek letters {{angle bracket|Y}} and {{angle bracket|Z}} (or readopted, in the latter case) to write [[Greek language|Greek]] loanwords, placing them at the end of the alphabet. An attempt by the emperor [[Claudius]] to introduce three [[Claudian letters|additional letters]] {{angle bracket|Ↄ, Ⅎ, Ⱶ}} did not last. Thus, it was during the [[classical Latin]] period that the Latin alphabet contained 21 letters and 2 foreign letters:

[[File:Inscription displaying apices (from the shrine of the Augustales at Herculaneum).jpg|thumb|upright=1.35|The [[Apex (diacritic)|apices]] in this first-century inscription are very light. (There is one over the {{sm|ó}} in the first line.) The vowel ''I'' is written taller rather than taking an apex. The [[interpunct]]s are comma-shaped, an elaboration of a more typical triangular shape. From the shrine of the [[Sodales Augustales|Augustales]] at [[Herculaneum]].]]

The Latin names of some of these letters are disputed; for example, {{angle bracket|H}} may have been called {{IPA|la|ˈaha|}} or {{IPA|la|ˈaka|}}.<ref>{{cite web |url = http://blog.oup.com/2013/08/alphabet-soup-letter-h-y-origin-etymology/ |title = Alphabet soup, part 2: H and Y |last=Liberman|first=Anatoly|date=7 August 2013|work=Oxford Etymologist|publisher=Oxford University Press|access-date=3 October 2013}}</ref> In general the Romans did not use the traditional ([[Phoenician alphabet|Semitic]]-derived) names as in Greek: the names of the [[plosives]] were formed by adding {{IPA|/eː/}} to their sound (except for {{angle bracket|K}} and {{angle bracket|Q}}, which needed different vowels to be distinguished from {{angle bracket|C}}) and the names of the [[continuant]]s consisted as a rule either of the bare sound, or the sound preceded by {{IPA|/e/}}.

The letter {{angle bracket|Y}} when introduced was probably called "hy" {{IPA|/hyː/}} as in Greek, the name [[upsilon]] not being in use yet, but this was changed to {{lang|la|i Graeca}} ("Greek i") as Latin speakers had difficulty distinguishing its foreign sound {{IPA|/y/}} from {{IPA|/i/}}. {{angle bracket|Z}} was given its Greek name, [[zeta (letter)|zeta]]. This scheme has continued to be used by most modern European languages that have adopted the Latin alphabet. For the Latin sounds represented by the various letters see [[Latin spelling and pronunciation]]; for the names of the letters in English see [[English alphabet]].

[[diacritic mark|Diacritics]] were not regularly used, but they did occur sometimes, the most common being the [[apex (diacritic)|apex]] used to mark [[long vowel]]s, which had previously sometimes been written doubled. However, in place of taking an apex, the letter i was written [[long i|taller]]: {{angle bracket|{{sm|á é ꟾ ó v́}}}}. For example, what is today transcribed {{lang|la|Lūciī a fīliī}} was written {{angle bracket|{{sm|lv́ciꟾ·a·fꟾliꟾ}}}} in the inscription depicted.
Some letters have more than one form in [[epigraphy]].
Latinists have treated some of them especially such as {{angbr|[[Ꟶ]]}}, a variant of {{angbr|H}} found in [[Roman Gaul]].
[[File:Musée Saint-Raymond - 2016-06-18 - US 2185 - 2037.jpg|thumb|Inscription with triangle-shaped interpunct]]
The primary mark of punctuation was the [[interpunct]], which was used as a [[word divider]], though it fell out of use after 200 AD.

[[Old Roman cursive]] script, also called [[majuscule]] cursive and Capitalis cursive, was the everyday form of handwriting used for writing letters, by merchants writing business accounts, by schoolchildren learning the Latin alphabet, and even emperors issuing commands. A more formal style of writing was based on [[Roman square capitals]], but cursive was used for quicker, informal writing. It was most commonly used from about the 1st century BC to the 3rd century, but it probably existed earlier than that. It led to [[Uncial script|Uncial]], a [[majuscule]] script commonly used from the [[3rd century|3rd]] to [[8th century|8th]] centuries AD by Latin and Greek scribes.
[[Tironian notes]] were a [[shorthand]] system consisting of thousands of signs.

[[New Roman cursive]] script, also known as [[lower case|minuscule]] cursive, was in use from the 3rd century to the 7th century, and uses letter forms that are more recognizable to modern eyes; {{angle bracket|a}}, {{angle bracket|b}}, {{angle bracket|d}}, and {{angle bracket|e}} had taken a more familiar shape, and the other letters were proportionate to each other. This script evolved into a variety of regional medieval scripts (for example, the [[Merovingian script|Merovingian]], [[Visigothic script|Visigothic]] and [[Beneventan script|Benevantan]] scripts), to be later supplanted by the [[Carolingian minuscule]].

===Medieval and later developments===
[[File:Ioanne Arnoldo 1541.PNG|thumb|upright=1.35|''De chalcographiae inventione'' (1541, [[Mainz]]) with the 23 letters. [[J]], [[U]] and [[W]] are missing.]]
[[File:Rekenaar 1553.jpg|thumb|upright=1.35|[[Jeton]] from [[Nuremberg]], {{circa|1553}}]]

It was not until the [[Middle Ages]] that the letter {{angle bracket|[[W]]}} (originally a [[ligature (typography)|ligature]] of two {{angle bracket|[[V]]}}s) was added to the Latin alphabet, to represent sounds from the [[Germanic language]]s which did not exist in medieval Latin, and only after the [[Renaissance]] did the convention of treating {{angle bracket|[[I]]}} and {{angle bracket|[[U]]}} as [[vowel]]s, and {{angle bracket|[[J]]}} and {{angle bracket|[[V]]}} as [[consonant]]s, become established. Prior to that, the former had been merely [[allograph]]s of the latter.{{Citation needed|date=July 2018}}

With the fragmentation of political power, the [[Palaeography|style of writing]] changed and varied greatly throughout the Middle Ages, even after the invention of the [[printing press]]. Early deviations from the classical forms were the [[uncial script]], a development of the [[Old Roman cursive]], and various so-called minuscule scripts that developed from [[New Roman cursive]], of which the [[insular script]] developed by Irish [[Intellectual|literati]] and derivations of this, such as [[Carolingian minuscule]] were the most influential, introducing the [[lower case]] forms of the letters, as well as other writing conventions that have since become standard.

The languages that use the [[Latin script]] generally use [[capital letters]] to begin paragraphs and sentences and [[Noun#Proper nouns and common nouns|proper nouns]]. The rules for [[capitalization]] have changed over time, and different languages have varied in their rules for capitalization. [[Old English language|Old English]], for example, was rarely written with even proper nouns capitalized, whereas [[Modern English]] writers and printers of the 17th and 18th century frequently capitalized most and sometimes all nouns;<ref>{{cite book |url = https://books.google.com/books?id=Kh_RZhvHk0YC&q=%22as+is+done+systematically+in+modern+German%22 |title=The Cambridge Encyclopedia of the English Language|first=David|last=Crystal|date=4 August 2003|publisher=Cambridge University Press|isbn=9780521530330|via=Google Books}}</ref> for example, from the preamble of the [[United States Constitution]]:
{{blockquote|We the People of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defence, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United States of America.}}
This is still systematically done in modern [[German language|German]].
