The modern [[varieties of Chinese|Chinese varieties]] make frequent use of what are called [[classifier (linguistics)|classifier]]s or [[measure word]]s. One use of classifiers is when a [[noun]] is qualified by a [[numeral (linguistics)|numeral]] or [[demonstrative]]. In the Chinese equivalent of a phrase such as "three books" or "that person", it is normally necessary to insert an appropriate classifier between the numeral/demonstrative and the noun. For example, in [[Standard Chinese]],<ref group=note>All examples given in this article are from standard Mandarin Chinese, with pronunciation indicated using the [[pinyin]] system, unless otherwise stated. The script would often be identical in other varieties of Chinese, although the pronunciation would vary.</ref> the first of these phrases would be:

{{fs interlinear|lang=zh|indent=2|glossing=no abbr
|三 {{uline|本}} 书
|sān {{uline|běn}} shū
|three CLASSIFIER books
|"three books"}}

When a noun stands alone without any [[determiner]], no classifier is needed. There are also various other uses of classifiers: for example, when placed after a noun rather than before it, or when repeated, a classifier signifies a plural or indefinite quantity.

The terms ''classifier'' and ''measure word'' are frequently used interchangeably and as equivalents of the Chinese term {{lang-zh||s=量词|t=量詞|p=liàngcí|labels=no|out=p}}. However, the two are sometimes distinguished, with ''classifier'' denoting a particle without any particular meaning of its own, as in the example above, and ''measure word'' denoting a word for a particular quantity or measurement of something, such as 'drop', 'cupful', or 'liter'. The latter type also includes certain words denoting lengths of time, units of currency, etc. These two types are alternatively called ''count-classifier'' and ''mass-classifier'', since the first type can only meaningfully be used with [[count noun]]s, while the second is used particularly with [[mass noun]]s. However, the grammatical behavior of words of the two types is largely identical.

Most nouns have one or more particular classifiers associated with them, often depending on the nature of the things they denote. For example, many nouns denoting flat objects such as tables, papers, beds, and benches use the classifier {{lang-zh|s=张|t=張|p=zhāng|labels=no|out=p}}, whereas many long and thin objects use {{lang-zh|s=条|t=條|p=tiáo|labels=no|out=p}}. The total number of classifiers in Chinese may be put at anywhere from a few dozen to several hundred, depending on how they are counted. The classifier {{lang-zh|s=个|t=個|p=gè|labels=no|out=p}}, apart from being the standard classifier for many nouns, also serves as a ''general classifier'', which may often be used in place of other classifiers; in informal and spoken language, native speakers tend to use this classifier far more than any other, even though they know which classifier is "correct" when asked. Mass-classifiers might be used with all sorts of nouns with which they make sense: for example, {{lang-zh|c=盒|p=hé|l=box|labels=no|out=p}} may be used to denote boxes of objects, such as light bulbs or books, even though those nouns would be used with their own appropriate count-classifiers if being counted as individual objects. Researchers have differing views as to how classifier–noun pairings arise: some regard them as being based on innate [[semantic]] features of the noun (for example, all nouns denoting "long" objects take a certain classifier because of their inherent length), while others see them as motivated more by analogy to [[Prototype theory|prototypical]] pairings—for example, 'dictionary' comes to take the same classifier as the more common word 'book'. There is some variation in the pairings used, with speakers of [[Varieties of Chinese|different dialects]] often using different classifiers for the same item. Some linguists have proposed that the use of classifier phrases may be guided less by grammar and more by stylistic or [[Pragmatics (linguistics)|pragmatic]] concerns on the part of a speaker who may be trying to [[Focus (linguistics)|foreground]] new or important information.

Many other languages of the [[Mainland Southeast Asia linguistic area]] exhibit similar classifier systems, leading to speculation about the origins of the Chinese system. Ancient classifier-like constructions, which used a repeated noun rather than a special classifier, are attested in [[Old Chinese]] as early as 1400 BCE, but true classifiers did not appear in these phrases until much later. Originally, classifiers and numbers came after the noun rather than before, and probably moved before the noun sometime after 500 BCE. The use of classifiers did not become a mandatory part of [[Old Chinese]] grammar until around 1100 CE. Some nouns became associated with specific classifiers earlier than others; the earliest probably being nouns that signified culturally valued items such as horses and poems. Many words that are classifiers today started out as full nouns; in some cases their meanings have been gradually [[Semantic bleaching|bleached]] away so that they are now used only as classifiers.

==Usage==
In Chinese, a [[numeral (linguistics)|numeral]] cannot usually quantify a [[noun]] by itself; instead, the language relies on [[classifier (linguistics)|classifier]]s, commonly also referred to as [[measure word]]s.<ref group=note>Across different [[varieties of Chinese]], classifier-noun clauses have slightly different interpretations (particularly in the interpretation of [[definiteness]] in classified nouns as opposed to [[bare nouns]]), but the requirement that a classifier come between a number and a noun is more or less the same in the major varieties {{Harv|Cheng|Sybesma|2005}}.</ref> When a noun is preceded by a number, a [[demonstrative]] such as ''this'' or ''that'', or certain [[quantifier (linguistics)|quantifiers]] such as ''every'', a classifier must normally be inserted before the noun.<ref name=LiThomp104>{{Harvnb|Li|Thompson|1981|p=104}}</ref> Thus, while English speakers say "one person" or "this person", [[Mandarin Chinese]] speakers say respectively:

{{columns-start}}
{{fs interlinear|lang=zh|indent=2|一 {{uline|个}} 人|yí {{uline|ge}} rén|one {{uline|CL}} person|"one person"}}
{{column}}
{{fs interlinear|lang=zh|indent=2|这 {{uline|个}} 人|zhè {{uline|ge}} rén|this {{uline|CL}} person|"this person"}}
{{columns-end}}

If a noun is preceded by both a demonstrative and a number, the demonstrative comes first.<ref name=Hu13>{{Harvnb|Hu|1993|p=13}}</ref> (This is just as in English, e.g. "these three cats".) If an [[adjective]] modifies the noun, it typically comes after the classifier and before the noun. The general structure of a classifier phrase is
<div class="center"><blockquote style="font-size: 120%;">{{green|demonstrative}}&nbsp;–&nbsp;{{teal|number}}&nbsp;–&nbsp;{{red|{{du|classifier|red}}}}&nbsp;–&nbsp;{{brown|adjective}}&nbsp;–&nbsp;{{purple|noun}}</blockquote></div>

The tables below give examples of common types of classifier phrases.<ref>The examples are adapted from those given in {{Harvtxt|Hu|1993|p=13}}, {{Harvtxt|Erbaugh|1986|pp=403–404}}, and {{Harvtxt|Li|Thompson|1981|pp=104–105}}.</ref> While most English nouns do not require classifiers or measure words (in English, both “five dogs” and “five cups of coffee” are grammatically correct), nearly all Chinese nouns do; thus, in the first table, phrases that have no classifier in English have one in Chinese.

On the other hand, when a noun is not counted or introduced with a demonstrative, a classifier is not necessary:<ref name="Zhang47">{{Harvnb|Zhang|2007|p=47}}</ref> for example, there is a classifier in
{{fs interlinear|lang=zh|indent=2|三 {{uline|辆}} 车|sān liàng chē|three {{uline|CL}} car|'three cars'}}

but not in
{{fs interlinear|lang=zh|indent=2|我 的 车|wǒ de chē|me POSS car|'my car'}}

Furthermore, numbers and demonstratives are often not required in Chinese, so speakers may choose not to use one—and thus not to use a classifier. For example, to say "[[Zhang San]] turned into a tree", both are acceptable:<ref name=Li1119>{{Harvnb|Li|2000|p=1119}}</ref> The use of classifiers after demonstratives is in fact optional.<ref>{{Harvnb|Sun|2006|p=159}}</ref>

{{fs interlinear|lang=zh|indent=2|张 三 变成 了 一 {{uline|棵}} 树|Zhāng Sān biànchéng -le yì {{uline|kē}} shù|Zhang San become PAST one {{uline|CL}} tree|}}
{{fs interlinear|lang=zh|indent=2|张 三 变成 了 树|Zhāng Sān biànchéng -le shù|Zhang San become PAST tree|}}

It is also possible for a classifier alone to qualify a noun, the numeral being omitted, as in
{{fs interlinear|lang=zh|indent=2|买 {{uline|匹}} 马|mǎi {{uline|pǐ}} mǎ|buy {{uline|CL}} horse|"buy a horse"<ref>{{Harvnb|Sun|2006|p=160}}</ref>}}

===Specialized uses===
[[File:Trafficjamdelhi.jpg|right|thumb|The phrase {{fs interlinear|lang=zh|indent=1|车 {{uline|辆}}|chē {{uline|liàng}}|car {{uline|CL}}|}} has the classifier after the noun. It could refer, for example, to "the cars on the road".|alt=A traffic jam]]

In addition to their uses with numbers and demonstratives, classifiers have some other functions. A classifier placed after a noun expresses a plural or indefinite quantity of it. For example:

{{fs interlinear|lang=zh|indent=2|书 {{uline|本}}|shū {{uline|běn}}|book {{uline|CL}}|'the books' (e.g. on a shelf, or in a library)}}

whereas the standard pre-nominal construction
{{fs interlinear|lang=zh|indent=2|一 {{uline|本}} 书|yī {{uline|běn}} shū|one {{uline|CL}} book|'one book'<ref name=LiThomp82>{{Harvnb|Li|Thompson|1981|p=82}}</ref>}}

Many classifiers may be [[reduplicated]] to mean 'every'. For example:

{{fs interlinear|lang=zh|indent=2|{{uline|个}} {{uline|个}} 人
|{{uline|gè}} {{uline|ge}} rén
|{{uline|CL}} {{uline|CL}} person
|'every person'<ref group="note">Although {{zhi|c=每{{uline|每}}个人}} is more generally used to mean 'every person' in this case.</ref><ref name=LiThomp34-5>{{Harvnb|Li|Thompson|1981|pp=34–35}}</ref>
}}

A classifier used along with 一 ({{Transliteration|zh|yī}} 'one') and after a noun conveys a meaning close to 'all of' or 'the entire' or 'a ___full of'.<ref name=LiThomp111>{{Harvnb|Li|Thompson|1981|p=111}}</ref> This sentence uses the classifier {{lang|zh|片}}&nbsp;({{Transliteration|zh|piàn}} 'slice'), which refers to the sky, not the clouds.<ref group=note>See, for example, similar results in the Chinese corpus of the Center for Chinese Linguistics at [[Peking University]]: [http://ccl.pku.edu.cn:8080/ccl_corpus/search?dir=xiandai&q=%E5%A4%A9%E7%A9%BA%E4%B8%80%E7%89%87&neighborSortLength=0&maxLeftLength=30&maxRightLength=30&start=0&num=50&index=FullIndex&outputFormat=HTML&orderStyle=score&encoding=UTF-8 天空一片], retrieved on 3 June 2009.</ref>

{{fs interlinear|lang=zh|indent=2
|天空 一 {{uline|片}} 云
|tiānkōng yī {{uline|piàn}} yún
|sky one {{uline|CL}} cloud
|"the sky was full of clouds"}}

Classifiers may also indicate possession. For example, the Standard Chinese equivalent of 'my book' would often be {{lang|zh|我的书}}&nbsp;({{Transliteration|zh|wǒ de shū}}), but in Cantonese this would typically be expressed as

{{fs interlinear|lang=yue|indent=2
|我 {{uline|本}} 书
|ngo4 bun2 syu1
|me CL.POSS book
|"my book"}}

with the classifier serving as a possessive marker roughly equivalent to English ''s''.

== Types ==
The vast majority of classifiers are those that count or classify nouns (''nominal classifiers'', as in all the examples given so far, as opposed to ''[[#Verbal classifiers|verbal classifiers]]'').<ref name=Hu9>{{Harvnb|Hu|1993|p=9}}</ref> These are further subdivided into ''count-classifiers'' and ''mass-classifiers'', described below. In everyday speech, people often use the term "measure word", or its literal Chinese equivalent {{lang|zh|量词}}&nbsp;{{Transliteration|zh|liàngcí}}, to cover all Chinese count-classifiers and mass-classifiers,<ref name=Li1116Hu7WangHe8>{{Harvnb|Li|2000|p=1116}}; {{Harvnb|Hu|1993|p=7}}; {{Harvnb|Wang|1994|pp=22, 24–25}}; {{Harvnb|He|2001|p=8}}. Also see the usage in {{Harvtxt|Fang|Connelly|2008}} and most introductory Chinese textbooks.</ref> but the types of words grouped under this term are not all the same. Specifically, the various types of classifiers exhibit numerous differences in meaning, in the kinds of words they attach to, and in [[syntactic]] behavior.

Chinese has a large number of nominal classifiers; estimates of the number in Mandarin range from "several dozen"<ref name=LiThomp105>{{Harvnb|Li|Thompson|1981|p=105}}</ref> or "about 50",<ref name=Chao79>{{Harvnb|Chao|1968|loc=section 7.9}}</ref> to over 900.<ref name=Zhang44>{{Harvnb|Zhang|2007|p=44}}</ref> The range is so large because some of these estimates include all types of classifiers while others include only count-classifiers,<ref group=note>In addition to the count-mass distinction and nominal-verbal distinction described below, various linguists have proposed many additional divisions of classifiers by type. {{Harvtxt|He|2001|loc=chapters 2 and 3}} contains a review of these.</ref> and because the idea of what constitutes a "classifier" [[#other names|has changed over time]]. Today, regular dictionaries include 120 to 150 classifiers;<ref name=Erbaugh403Fangix>{{Harvnb|Erbaugh|1986|p=403}}; {{Harvnb|Fang|Connelly|2008|p=ix}}</ref> the 8822-word ''Syllabus of Graded Words and Characters for Chinese Proficiency''<ref group=note>The ''Syllabus of Graded Words and Characters for Chinese Proficiency'' is a standardized measure of vocabulary and character recognition, used in the [[People's Republic of China]] for testing middle school students, high school students, and foreign learners.

===Count-classifiers and mass-classifiers===
{{Quote box | quote=A '''classifier''' categorizes a class of nouns by picking out some [[Salience (semiotics)|salient]] perceptual properties...which are permanently associated with entities named by the class of nouns; a '''measure word''' does not categorize but denotes the quantity of the entity named by a noun. | source = — {{Harvtxt|Tai|1994|p=2}}, emphasis added | align=right | width=25% | bgcolor=#FFFFE0  | salign=right}}

Within the set of nominal classifiers, linguists generally draw a distinction between "count-classifiers" and "mass-classifiers". True ''count-classifiers''<ref group=note>Count-classifiers have also been called "individual classifiers", {{Harv|Chao|1968|p=509}}, "qualifying classifiers" ({{Harvnb|Zhang|2007|p=45}}; {{Harvnb|Hu|1993|p=10}}), and just "classifiers" {{Harv|Cheng|Sybesma|1998|p=3}}.</ref> are used for naming or counting a single [[count noun]],<ref name=Zhang44/> and have no direct translation in English; for example:

{{fs interlinear|lang=zh|indent=2|一 {{uline|本}} 书|yì {{uline|běn}} shū|one {{uline|CL}} book|"one book" or "a book"<ref name=Erbaugh404>{{Harvnb|Erbaugh|1986|p=404}}</ref>}}

Furthermore, count-classifiers cannot be used with [[mass noun]]s: just as an English speaker cannot ordinarily say *"five muds", a Chinese speaker cannot say

{{fs interlinear|lang=zh|indent=2|* 五 {{uline|个}} 泥|{} wǔ {{uline|ge}} nì|{} five {{uline|CL}} mud|}}

For such mass nouns, one must use ''mass-classifiers''.<ref name=Zhang44/><ref group=note>Mass-classifiers have also been called "measure words", "massifiers" {{Harv|Cheng|Sybesma|1998|p=3}}, "non-individual classifiers" {{Harv|Chao|1968|p=509}}, and "quantifying classifiers" ({{Harvnb|Zhang|2007|p=45}}; {{Harvnb|Hu|1993|p=10}}). The term "mass-classifier" is used in this article to avoid ambiguous usage of the term "measure word", which is often used in everyday speech to refer to both count-classifiers and mass-classifiers, even though in technical usage it only means mass-classifiers {{Harv|Li|2000|p=1116}}.</ref>

Mass-classifiers (true [[measure word]]s) do not pick out inherent properties of an individual noun like count-classifiers do; rather, they lump nouns into countable units. Thus, mass-classifiers can generally be used with multiple types of nouns; for example, while the mass-classifier {{lang|zh|盒}}&nbsp;({{Transliteration|zh|hé}}, box) can be used to count boxes of lightbulbs or of books

{{columns-start}}
{{fs interlinear|lang=zh|indent=2|一 {{uline|盒}} 灯泡|yì {{uline|hé}} dēngpào|"one {{uline|box}} of lightbulbs"}}
{{column}}
{{fs interlinear|lang=zh|indent=2|一 {{uline|盒}} 教材|yì {{uline|hé}} jiàocái|"one {{uline|box}} of textbooks"}}
{{columns-end}}

each of these nouns must use a different count-classifier when being counted by itself.

{{columns-start}}
{{fs interlinear|lang=zh|indent=2|一 {{uline|盏}} 灯泡|yì {{uline|zhǎn}} dēngpào|"one lightbulb"}}
{{column}}
{{fs interlinear|lang=zh|indent=2|一 {{uline|本}} 教材|yì {{uline|běn}} jiàocái|"one textbook"}}
{{columns-end}}

While count-classifiers have no direct English translation, mass-classifiers often do:

{{columns-start}}
{{fs interlinear|lang=zh|indent=2|一 {{uline|个}} 人|yí {{uline|ge}} rén|one {{uline|CL}} person|"one person" or "a person"}}
{{column}}
{{fs interlinear|lang=zh|indent=2|一 {{uline|群}} 人|yì {{uline|qún}} rén|one {{uline|crowd}} person|"a crowd of people"}}
{{columns-end}}

All languages, including English, have mass-classifiers, but count-classifiers are unique to certain "classifier languages", and are not a part of English grammar apart from a few exceptional cases such as head of livestock.<ref name=Tai3Allan285-6/>

Within the range of mass-classifiers, authors have proposed subdivisions based on the manner in which a mass-classifier organizes the noun into countable units. One of these is ''measurement units'' (also called "standard measures"),<ref name=Ahrensn3>{{Harvnb|Ahrens|1994|p=239, note 3}}</ref> which all languages must have in order to measure items; this category includes units such as kilometers, liters, or pounds<ref name=LiThomp105Zhang44Erbaughn5>{{Harvnb|Li|Thompson|1981|p=105}}; {{Harvnb|Zhang|2007|p=44}}; {{Harvnb|Erbaugh|1986|p=118, note 5}}</ref> (see [[List of Chinese classifiers#Measurement units|list]]). Like other classifiers, these can also stand without a noun.<ref name=LiThomp105-7>{{Harvnb|Li|Thompson|1981|pp=105–107}}</ref> Units of currency behave similarly.

Other proposed types of mass-classifiers include

The difference between count-classifiers and mass-classifiers can be described as one of quantifying versus categorizing: in other words, mass-classifiers ''create'' a unit by which to measure something (i.e. boxes, groups, chunks, pieces, etc.), whereas count-classifiers simply ''name'' an existing item.<ref name=ChengSybesma3Tai2>{{Harvnb|Cheng|Sybesma|1998|p=3}}; {{Harvnb|Tai|1994|p=2}}</ref> Most words can appear with both count-classifiers and mass-classifiers; for example, pizza can be described both using a count-classifier and using a mass-classifier.

{{columns-start}}
{{fs interlinear|lang=zh|indent=2|一 {{uline|张}} 比萨|yì {{uline|zhāng}} bǐsà|"one pizza", literally "one {{uline|pie}} of pizza"}}
{{column}}
{{fs interlinear|lang=zh|indent=2|一 {{uline|块}} 比萨|yí {{uline|kuài}} bǐsà|"one {{uline|piece}} of pizza"}}
{{columns-end}}

In addition to these semantic differences, there are differences in the grammatical behaviors of count-classifiers and mass-classifiers;<ref name=WangChengSybesma>{{Harvnb|Wang|1994|pp=27–36}}; {{Harvnb|Cheng|Sybesma|1998}}</ref> for example, mass-classifiers may be modified by a small set of adjectives, as in:

{{fs interlinear|lang=zh|indent=2|一 大 {{uline|群}} 人|yí dà {{uline|qún}} rén|"a big {{uline|crowd}} of people"}}

Whereas count-classifiers usually may not. For example, this is never said:

{{fs interlinear|lang=zh|indent=2|* 一 大 {{uline|个}} 人|{} yí dà {{uline|ge}} rén|}}

Instead the adjective must modify the noun:<ref name=ChengSybesma1998-3-5>{{Harvnb|Cheng|Sybesma|1998|pp=3–5}}</ref>

{{fs interlinear|lang=zh|indent=2|一 {{uline|个}} 大 人|yí {{uline|ge}} dà rén|"a big person"}}

Another difference is that count-classifiers may often be replaced by a "general" classifier {{lang|zh|个}} ({{lang|zh|個}}), ''gè'' with no apparent change in meaning, whereas mass-classifiers may not.<ref name=Wang29-30>{{Harvnb|Wang|1994|pp=29–30}}</ref> Syntacticians [[Lisa Cheng (linguist)|Lisa Cheng]] and Rint Sybesma propose that count-classifiers and mass-classifiers have different underlying syntactic structures, with count-classifiers forming "classifier phrases",<ref group=note>"Classifier phrases" are similar to [[noun phrase]]s, but with a classifier rather than a noun as the [[head (linguistics)|head]] {{Harv|Cheng|Sybesma|1998|pp=16–17}}.</ref> and mass-classifiers being a sort of [[relative clause]] that only ''looks'' like a classifier phrase.<ref name=ChengSybesma>{{Harvnb|Cheng|Sybesma|1998}}</ref> The distinction between count-classifiers and mass-classifiers is often unclear, however, and other linguists have suggested that count-classifiers and mass-classifiers may not be fundamentally different. They posit that "count-classifier" and "mass-classifier" are the extremes of a continuum, with most classifiers falling somewhere in between.<ref name=Ahrensn5Wang>{{Harvnb|Ahrens|1994|p=239, note 5}}; {{Harvnb|Wang|1994|pp=26–27, 37–48}}</ref>

===Verbal classifiers===

There is a set of "[[List of Chinese classifiers#Verbal classifiers|verbal classifiers]]" used specifically for counting the number of times an action occurs, rather than counting a number of items; this set includes {{lang|zh|次}} ''cì'', {{lang|zh|遍}}/{{lang|zh|徧}} ''biàn'', {{lang|zh|回}} ''huí'', and {{lang|zh|下}} ''xià'', which all roughly translate to "times".<ref name=He4244>{{Harvnb|He|2001|pp=42, 44}}</ref> For example:

{{fs interlinear|lang=zh|indent=2|我 去 过 三 {{uline|次}} 北京
|wǒ qù guo sān {{uline|cì}} Běijīng
|I go PAST three {{uline|CL}} Beijing
|"I have been to Beijing three {{uline|times}}"<ref name=Zhang44LiThomp110>{{Harvnb|Zhang|2007|p=44}}; {{Harvnb|Li|Thompson|1981|p=110}}; {{Harvnb|Fang|Connelly|2008|p=x}}</ref>}}

These words can also form compound classifiers with certain nouns, as in {{lang|zh|人次}} ''rén cì'' "person-time", which can be used to count (for example) visitors to a museum in a year (where visits by the same person on different occasions are counted separately).

Another type of verbal classifier indicates the tool or implement used to perform the action. An example is found in the sentence:

{{fs interlinear|lang=zh|indent=2|
|他 踢 了 我 一 {{uline|脚}}
|tā tī le wǒ yī {{uline|jiǎo}}
|he kick PAST me one {{uline|foot}}
|"he kicked me"}}

The word {{lang|zh|脚}} ''jiǎo'', which usually serves as a simple noun meaning "foot", here functions as a verbal classifier reflecting the tool (namely the foot) used to perform the kicking action.

==Relation to nouns==
{{multiple image

In other dialects, such as Cantonese, {{lang|zh|條}} cannot be used to refer to {{lang|zh|櫈}}. Instead, {{lang|zh|張}} is used.

Different classifiers often correspond to different particular nouns. For example, books generally take the classifier {{lang|zh|本}}&nbsp;{{tlit|zh|běn}}, flat objects take {{lang|zh|张}}&nbsp;({{lang|zh|張}})&nbsp;{{tlit|zh|zhāng}}, animals take {{lang|zh|只}}&nbsp;({{lang|zh|隻}})&nbsp;{{tlit|zh|zhī}}, machines take {{lang|zh|台}}&nbsp;{{tlit|zh|tái}}, and large buildings and mountains take {{lang|zh|座}}&nbsp;{{tlit|zh|zuò}}. Within these categories are further subdivisions—while most animals take {{lang|zh|只}}&nbsp;({{lang|zh|隻}})&nbsp;{{tlit|zh|zhī}}, domestic animals take {{lang|zh|头}}&nbsp;({{lang|zh|頭}})&nbsp;{{tlit|zh|tóu}}, long and flexible animals take {{lang|zh|条}}&nbsp;({{lang|zh|條}})&nbsp;{{tlit|zh|tiáo}}, and horses take {{lang|zh|匹}}&nbsp;{{tlit|zh|pǐ}}. Likewise, while long things that are flexible (such as ropes) often take {{lang|zh|条}}&nbsp;({{lang|zh|條}})&nbsp;{{tlit|zh|tiáo}}, long things that are rigid (such as sticks) take {{lang|zh|根}}&nbsp;{{tlit|zh|gēn}}, unless they are also round (like pens or cigarettes), in which case in some dialects they take {{lang|zh|支}}&nbsp;{{tlit|zh|zhī}}.<ref name=TaiTaiWang>{{Harvnb|Tai|1994|pp=7–9}}; {{Harvnb|Tai|Wang|1990}}</ref> Classifiers also vary in how specific they are; some (such as {{lang|zh|朵}}&nbsp;{{tlit|zh|duǒ}} for flowers and  other similarly clustered items) are generally only used with one type, whereas others (such as {{lang|zh|条}}&nbsp;({{lang|zh|條}})&nbsp;{{tlit|zh|tiáo}} for long and flexible things, one-dimensional things, or abstract items like news reports)<ref group=note>This may be because official documents during the [[Han dynasty]] were written on long bamboo strips, making them 'strips of business' {{Harv|Ahrens|1994|p=206}}.</ref> are much less restricted.<ref name=Erbaugh111>{{Harvnb|Erbaugh|1986|p=111}}</ref> Furthermore, there is not a one-to-one relationship between nouns and classifiers: the same noun may be paired with different classifiers in different situations.<ref name=He239>{{Harvnb|He|2001|p=239}}</ref> The specific factors that govern which classifiers are paired with which nouns have been a subject of debate among linguists.

===Categories and prototypes===
While mass-classifiers do not necessarily bear any semantic relationship to the noun with which they are used (e.g. ''box'' and ''book'' are not related in meaning, but one can still say "a box of books"), count-classifiers do.<ref name=ChengSybesma/> The precise nature of that relationship, however, is not certain, since there is so much variability in how objects may be organized and categorized by classifiers. Accounts of the semantic relationship may be grouped loosely into ''categorical'' theories, which propose that count-classifiers are matched to objects solely on the basis of inherent features of those objects (such as length or size), and ''prototypical'' theories, which propose that people learn to match a count-classifier to a specific prototypical object and to other objects that are like that prototype.<ref>{{Harvnb|Tai|1994|pp=3–5}}; {{Harvnb|Ahrens|1994|pp=208–12}}</ref>

The categorical, "[[Categories (Aristotle)|classical]]"<ref name=Tai3Ahrens209-10>{{Harvnb|Tai|1994|p=3}}; {{Harvnb|Ahrens|1994|pp=209–10}}</ref> view of classifiers was that each classifier represents a category with a set of conditions; for example, the classifier {{lang|zh|条}}&nbsp;({{lang|zh-Hant-TW|2=條}})&nbsp;''tiáo'' would represent a category defined as all objects that meet the conditions of being long, thin, and one-dimensional—and nouns using that classifier must fit all the conditions with which the category is associated.  Some common semantic categories into which count-classifiers have been claimed to organize nouns include the categories of shape (long, flat, or round), size (large or small), consistency (soft or hard), [[animacy]] (human, animal, or object),<ref name=Tai5Allan>{{Harvnb|Tai|1994|p=5}}; {{Harvnb|Allan|1977}}</ref> and function (tools, vehicles, machines, etc.).<ref name=Hu1>{{Harvnb|Hu|1993|p=1}}</ref>

{{multiple image
 | footer    = James Tai and Wang Lianqing found that the horse classifier {{lang|zh|匹}}&nbsp;''pǐ'' is sometimes used for [[mule]]s and [[camel]]s, but rarely for the less "horse-like" [[donkey]]s, suggesting that the choice of classifiers is influenced by prototypal closeness.<ref name=Tai12/>

}}

On the other hand, proponents of [[prototype theory]] propose that count-classifiers may not have innate definitions, but are associated with a noun that is prototypical of that category, and nouns that have a "family resemblance" with the prototype noun will want to use the same classifier.<ref group=note>The theory described in {{Harvtxt|Ahrens|1994}} and {{Harvtxt|Wang|1994}} is also referred to within those works as a "prototype" theory, but differs somewhat from the version of prototype theory described here; rather than claiming that individual prototypes are the ''source'' for classifier meanings, these authors believe that classifiers still are based on categories with features, but that the categories have many features, and "prototypes" are words that have all the features of that category whereas other words in the category only have some features.  In other words, "there are core and marginal members of a category.... a member of a category does not necessarily possess all the properties of that category" {{Harv|Wang|1994|p=8}}. For instance, the classifier {{lang|zh|棵}}&nbsp;''kē'' is used for the category of trees, which may have features such as "has a trunk", "has leaves", and "has branches", "is deciduous"; maple trees would be prototypes of the category, since they have all these features, whereas palm trees only have a trunk and leaves and thus are not prototypical {{Harv|Ahrens|1994|pp=211–12}}.</ref> For example, ''horse'' in Chinese uses the classifier {{lang|zh|匹}}&nbsp;''pǐ'', as in:
{{fs interlinear|lang=zh|indent=2|三 {{uline|匹}} 马|sān {{uline|pǐ}} mǎ|"three horses"}}
In modern Chinese the word {{lang|zh|匹}} has no meaning. Nevertheless, nouns denoting animals that look like horses will often also use this same classifier, and native speakers have been found to be more likely to use the classifier {{lang|zh|匹}} the closer an animal looks to a horse.<ref name=Tai12>{{Harvnb|Tai|1994|p=12}}</ref> Furthermore, words that do not meet the "criteria" of a semantic category may still use that category because of their [[association (psychology)|association]] with a prototype. For example, the classifier {{lang|zh|颗}}&nbsp;({{lang|zh-Hant-TW|2=顆}})&nbsp;''kē'' is used for small round items, as in:
{{fs interlinear|lang=zh|indent=2|一 {{uline|颗}} 子弹|yì {{uline|kē}} zǐdàn|"one bullet"}}
When words like {{lang|zh|原子弹}}&nbsp;(''yuánzǐdàn'', "atomic bomb") were later introduced into the language they also used this classifier (颗 [顆] kē), even though they are not small and round—therefore, their classifier must have been assigned because of the words' association with the word for bullet, which acted as a "prototype".<ref name=Zhang46-47>{{Harvnb|Zhang|2007|pp=46–47}}</ref> This is an example of "generalization" from prototypes: Erbaugh has proposed that when children learn count-classifiers, they go through stages, first learning a classifier-noun pair only, such as
{{fs interlinear|lang=zh|indent=2|{{uline|条}} 鱼|{{uline|tiáo}} yú|{{uline|CL}} fish|}}
then using that classifier with multiple nouns that are similar to the prototype (such as other types of fish), then finally using that set of nouns to generalize a semantic feature associated with the classifier (such as length and flexibility) so that the classifier can then be used with new words that the person encounters.<ref name=Erbaugh415Hu>{{Harvnb|Erbaugh|1986|p=415}}</ref>

Some classifier-noun pairings are arbitrary, or at least appear to modern speakers to have no semantic motivation.<ref name=Hu1Tai13Zhang55-6>{{Harvnb|Hu|1993|p=1}}; {{Harvnb|Tai|1994|p=13}}; {{Harvnb|Zhang|2007|pp=55–56}}</ref> For instance, the classifier {{lang|zh|部}}&nbsp;''bù'' may be used for movies and novels, but also for cars<ref name=Zhang55-56>{{Harvnb|Zhang|2007|pp=55–56}}</ref> and telephones.<ref name=GaoMalt1134>{{Harvnb|Gao|Malt|2009|p=1134}}</ref> Some of this arbitrariness may be due to what linguist [[James Tai]] refers to as "fossilization", whereby a count-classifier loses its meaning through historical changes but remains paired with some nouns. For example, the classifier {{lang|zh|匹}}&nbsp;''pǐ'' used for horses is meaningless today, but in [[Classical Chinese]] may have referred to a "team of two horses",<ref name=Morev79>{{Harvnb|Morev|2000|p=79}}</ref> a pair of horse skeletons,<ref name=Wang172-3>{{Harvnb|Wang|1994|pp=172–73}}</ref> or the pairing between man and horse.<ref name=Tai15>{{Harvnb|Tai|1994|p=15, note 7}}</ref><ref group=note>The apparent disagreement between the definitions provided by different authors may reflect different uses of these words in different time periods. It is well-attested that many classifiers underwent frequent changes of meaning throughout history ({{Harvnb|Wang|1994}}; {{Harvnb|Erbaugh|1986|pp=426–31}}; {{Harvnb|Ahrens|1994|pp=205–206}}), so {{lang|zh|匹}}&nbsp;''pǐ'' may have had all these meanings at different points in history.</ref> Arbitrariness may also arise when a classifier is [[Loanword|borrowed]], along with its noun, from a dialect in which it has a clear meaning to one in which it does not.<ref name=Tai13>{{Harvnb|Tai|1994|p=13}}</ref> In both these cases, the use of the classifier is remembered more by association with certain "prototypical" nouns (such as ''horse'') rather than by understanding of semantic categories, and thus arbitrariness has been used as an argument in favor of the prototype theory of classifiers.<ref name=Tai13/> Gao and Malt propose that both the category and prototype theories are correct: in their conception, some classifiers constitute "well-defined categories", others make "prototype categories", and still others are relatively arbitrary.<ref name=GaoMalt1133-1134>{{Harvnb|Gao|Malt|2009|pp=1133–4}}</ref>

===Neutralization===
In addition to the numerous "specific" count-classifiers described above,<ref group=note>Also called "sortal classifiers" ({{Harvnb|Erbaugh|2000|p=33}}; {{Harvnb|Biq|2002|p=531}}).</ref> Chinese has a ''general classifier'' {{lang|zh|个}} ({{lang|zh|個}}), pronounced {{Transliteration|zh|gè}} in Standard Chinese.<ref group=note>Kathleen Ahrens claimed in 1994 that the classifier for animals—{{lang|zh|只}} ({{lang|zh|隻}}), pronounced {{Transliteration|zh|zhī}} in Standard Chinese and {{lang|nan-Latn|chiah}} in [[Taiwanese Hokkien]]—is in the process of becoming a second general classifier in the Mandarin spoken in [[Taiwan]], and already is used as the general classifier in Taiwanese itself {{Harv|Ahrens|1994|p=206}}.</ref> This classifier is used for people, some abstract concepts, and other words that do not have special classifiers (such as {{zhi|c=汉堡包}} {{Transliteration|zh|hànbǎobāo}} 'hamburger'),<ref name=Hu12>{{Harvnb|Hu|1993|p=12}}</ref> and may also be used as a replacement for a specific classifier such as {{lang|zh|张}}&nbsp;({{lang|zh-Hant-TW|2=張}})&nbsp;{{Transliteration|zh|zhāng}} or {{lang|zh|条}}&nbsp;({{lang|zh-Hant-TW|2=條}})&nbsp;{{Transliteration|zh|tiáo}}, especially in informal speech. In Mandarin Chinese, it has been noted as early as the 1940s that the use of {{lang|zh|个}} is increasing and that there is a general tendency towards replacing specific classifiers with it.<ref name=Tzeng193>{{Harvnb|Tzeng|Chen|Hung|1991|p=193}}</ref> Numerous studies have reported that both adults and children tend to use {{lang|zh|个}} when they do not know the appropriate count-classifier, and even when they do but are speaking quickly or informally.<ref name=Zhang57>{{Harvnb|Zhang|2007|p=57}}</ref> The replacement of a specific classifier with the general {{lang|zh|个}} is known as classifier ''neutralization''<ref name=Ahrens212>{{Harvnb|Ahrens|1994|p=212}}</ref> ({{lang|zh|量词个化}} in Chinese, literally 'classifier {{zhi|c=个}}-ization'<ref name=He165>{{Harvnb|He|2001|p=165}}</ref>). This occurs especially often among children<ref name=ErbaughHu>{{Harvnb|Erbaugh|1986}}; {{Harvnb|Hu|1993}}</ref> and [[Aphasia|aphasics]] (individuals with damage to language-relevant areas of the brain),<ref name=Ahrens227-32>{{Harvnb|Ahrens|1994|pp=227–32}}</ref><ref>{{Harvnb|Tzeng|Chen|Hung|1991}}</ref> although normal speakers also neutralize frequently. It has been reported that most speakers know the appropriate classifiers for the words they are using and believe, when asked, that those classifiers are obligatory, but nevertheless use {{lang|zh|个}} without even realizing it in actual speech.<ref name=Erbaugh404-6Ahrens202-3>{{Harvnb|Erbaugh|1986|pp=404–406}}; {{Harvnb|Ahrens|1994|pp=202–203}}</ref> As a result, in everyday spoken Mandarin the general classifier is "hundreds of times more frequent"<ref name=Erbaugh404-6>{{Harvnb|Erbaugh|1986|pp=404–406}}</ref> than the specialized ones.<!-- He Jie, however, claims that this is only a trend in spoken language, and that specific classifiers are still frequent in written Chinese.<ref name=He336>{{Harvnb|He|2001|p=336}}</ref>-->

Nevertheless, {{lang|zh|个}} has not completely replaced other count-classifiers, and there are still many situations in which it would be inappropriate to substitute it for the required specific classifier.<ref name=Tzeng193/> There may be specific patterns behind which classifier-noun pairs may be "neutralized" to use the general classifier, and which may not. Specifically, words that are most prototypical for their categories, such as ''paper'' for the category of nouns taking the 'flat{{\}}square' classifier {{lang|zh|张}}&nbsp;({{lang|zh-Hant-TW|2=張}})&nbsp;{{Transliteration|zh|zhāng}}, may be less likely to be said with a general classifier.<ref name=Ahrensall>{{Harvnb|Ahrens|1994}}</ref>

===Variation in usage===

}}
It is not the case that every noun is only associated with one classifier. Across dialects and speakers there is great variability in the way classifiers are used for the same words, and speakers often do not agree which classifier is best.<ref name=TaiTaiWangErbaugh>{{Harvnb|Tai|1994}}; {{Harvnb|Erbaugh|2000|pp=34–35}}</ref> For example, for cars some people use {{lang|zh|部}}&nbsp;{{Transliteration|zh|bù}}, others use {{lang|zh|台}}&nbsp;{{Transliteration|zh|tái}}, and still others use {{lang|zh|辆}}&nbsp;({{lang|zh-Hant-TW|2=輛}})&nbsp;{{Transliteration|zh|liàng}}; [[Standard Cantonese|Cantonese]] uses {{lang|zh|架}}&nbsp;{{Transliteration|yue|gaa3}}. Even within a single dialect or a single speaker, the same noun may take different measure words depending on the style in which the person is speaking, or on different nuances the person wants to convey (for instance, measure words can reflect the speaker's judgment of or opinion about the object<ref name=He237>{{Harvnb|He|2001|p=237}}</ref>). An example of this is the word for person, {{lang|zh|人}}&nbsp;{{Transliteration|zh|rén}}, which uses the measure word {{lang|zh|个}}&nbsp;({{lang|zh-Hant-TW|2=個}})&nbsp;{{Transliteration|zh|gè}} normally, but uses the measure {{lang|zh|口}}&nbsp;{{Transliteration|zh|kǒu}} when counting number of people in a household, {{lang|zh|位}}&nbsp;{{Transliteration|zh|wèi}} when being particularly polite or honorific, and {{lang|zh|名}}&nbsp;{{Transliteration|zh|míng}} in formal written contexts;<ref name=FangixZhang53-4>{{Harvnb|Fang|Connelly|2008|p=ix}}; {{Harvnb|Zhang|2007|pp=53–54}}</ref> likewise, a group of people may be referred to by massifiers:

{{columns-start}}
{{fs interlinear|lang=zh|indent=2|一 {{uline|群}} 人|yì {{uline|qún}} rén|'a {{uline|group}} of people'}}
{{column}}
{{fs interlinear|lang=zh|indent=2|一 {{uline|帮}} 人|yì {{uline|bāng}} rén|'a {{uline|gang/crowd}} of people'}}
{{columns-end}}

The first is neutral, whereas the second implies that the people are unruly or otherwise being judged poorly.<ref name=He242>{{Harvnb|He|2001|p=242}}</ref>

Some count-classifiers may also be used with nouns that they are not normally related to, for metaphorical effect, as in:

{{fs interlinear|lang=zh|indent=2|一 {{uline|堆}} 烦恼|yì {{uline|duī}} fánnǎo|'a {{uline|pile}} of worries/troubles'<ref name=Shie76/>}}

Finally, a single word may have multiple count-classifiers that convey different meanings altogether—in fact, the choice of a classifier can even influence the meaning of a noun. By way of illustration:<ref name=Zhang52>{{Harvnb|Zhang|2007|p=52}}</ref>

{{columns-start}}
{{fs interlinear|lang=zh|indent=2|三 {{uline|节}} 课|sān {{uline|jié}} kè|'three class periods' (as in "I have three classes today"}}

{{columns-end}}

== Purpose ==
In research on classifier systems, and Chinese classifiers in particular, it has been asked why count-classifiers (as opposed to mass-classifiers) exist at all. Mass-classifiers are present in all languages since they are the only way to "count" mass nouns that are not naturally divided into units (for example, "three {{uline|splotches}} of mud" in English; *"three muds" is ungrammatical). On the other hand, count-classifiers are not mandatory, and are not present in most languages.<ref name=Tai3Allan285-6>{{Harvnb|Tai|1994|p=3}}; {{Harvnb|Allan|1977|pp=285–86}}; {{Harvnb|Wang|1994|p=1}}</ref><ref group=note>Although English does not have a productive system of count-classifiers and is not considered a "classifier language", it does have a few constructions—mostly archaic or specialized—that resemble count-classifiers, such as "X head of cattle" {{Harv|T'sou|1976|p=1221}}.</ref> Furthermore, count-classifiers are used with an "unexpectedly low frequency";<ref name=Erbaugh200034>{{Harvnb|Erbaugh|2000|p=34}}</ref> in many settings, speakers avoid specific classifiers by just using a bare noun (without a number or demonstrative) or using the general classifier {{lang|zh|个}}&nbsp;{{Transliteration|zh|gè}}.<ref name=ErbaughLi>{{Harvnb|Erbaugh|2000|pp=425–26}}; {{Harvnb|Li|2000}}</ref> Linguists and [[Linguistic typology|typologists]] such as [[Joseph Greenberg]] have suggested that specific count-classifiers are semantically redundant.<ref name=Zhang51>{{Harvnb|Zhang|2007|p=51}}</ref> Count-classifiers can be used stylistically, though,<ref name=FangixZhang53-4/> and can also be used to clarify or limit a speaker's intended meaning when using a vague or ambiguous noun; for example, the noun {{lang|zh|课}}&nbsp;{{Transliteration|zh|kè}} 'class' can refer to courses in a semester or specific class periods during a day, depending on whether the classifier {{lang|zh|门}}&nbsp;({{lang|zh-Hant-TW|2=門}})&nbsp;{{Transliteration|zh|mén}} or {{lang|zh|节}}&nbsp;({{lang|zh-Hant-TW|2=節}})&nbsp;{{Transliteration|zh|jié}} is used.<ref name=Zhang51-2>{{Harvnb|Zhang|2007|pp=51–52}}</ref>

One proposed explanation for the existence of count-classifiers is that they serve more of a cognitive purpose than a practical one: in other words, they provide a linguistic way for speakers to organize or categorize real objects.<ref name=Erbaugh425-6>{{Harvnb|Erbaugh|1986|pp=425–6}}</ref> An alternative account is that they serve more of a [[discourse|discursive]] and [[pragmatics (linguistics)|pragmatic]] function (a communicative function when people interact) rather than an abstract function within the mind.<ref name=ErbaughLi/> Specifically, it has been proposed that count-classifiers might be used to mark new or unfamiliar objects within a discourse,<ref name=Erbaugh425-6/> to introduce major characters or items in a story or conversation,<ref name=Sun>{{Harvnb|Sun|1988|p=298}}</ref> or to [[focus (linguistics)|foreground]] important information and objects by making them bigger and more [[salience (semiotics)|salient]].<ref name=Li>{{Harvnb|Li|2000}}</ref> In this way, count-classifiers might not serve an abstract grammatical or cognitive function, but may help in communication by making important information more noticeable and drawing attention to it.

=== Classifier phrases ===
[[File:Shang_dynasty_inscribed_tortoise_plastron.jpg|right|thumb|An [[oracle bone inscription]] from the [[Shang dynasty]]. Such inscriptions provide some of the earliest examples of the number phrases that may have eventually spawned Chinese classifiers.|alt=An off-white, ovular turtle shell with an inscription in ancient Chinese]]
[[Historical linguistics|Historical linguists]] have found that phrases consisting of nouns and numbers went through several structural changes in [[Old Chinese]] and [[Middle Chinese]] before classifiers appeared in them. The earliest forms may have been ''Number&nbsp;–&nbsp;Noun'', like English (e.g. 'five horses'), and the less common ''Noun&nbsp;–&nbsp;Number'' ('horses five'), both of which are attested in the [[oracle bone script]]s of Pre-Archaic Chinese (circa 1400&nbsp;BCE to 1000&nbsp;BCE).<ref name=Peyraube107Morev78-9>{{Harvnb|Peyraube|1991|p=107}}; {{Harvnb|Morev|2000|pp=78–79}}</ref> The first constructions resembling classifier constructions were ''Noun&nbsp;–&nbsp;Number&nbsp;–&nbsp;Noun'' constructions, which were also extant in Pre-Archaic Chinese but less common than ''Number&nbsp;–&nbsp;Noun''. In these constructions, sometimes the first and second nouns were identical (''N1&nbsp;–&nbsp;Number&nbsp;–&nbsp;N1'', as in "horses five horses") and other times the second noun was different, but semantically related (''N1&nbsp;–&nbsp;Number&nbsp;–&nbsp;N2''). According to some historical linguists, the ''N2'' in these constructions can be considered an early form of count-classifier and has even been called an "echo classifier"; this speculation is not universally agreed on, though.<ref name=Peyraube108>{{Harvnb|Peyraube|1991|p=108}}</ref> Although true count-classifiers had not appeared yet, mass-classifiers were common in this time, with constructions such as "wine&nbsp;–&nbsp;six&nbsp;–&nbsp;{{uline|yǒu}}" (the word {{lang|zh|酉}}&nbsp;{{Transliteration|zh|yǒu}} represented a wine container) meaning "six {{Transliteration|zh|yǒu}} of wine".<ref name=Peyraube108/> Examples such as this suggest that mass-classifiers predate count-classifiers by several centuries, although they did not appear in the same word order as they do today.<ref name=Peyraube110Wang171>{{Harvnb|Peyraube|1991|p=110}}; {{Harvnb|Wang|1994|pp=171–72}}</ref>

It is from this type of structure that count-classifiers may have arisen, originally replacing the second noun (in structures where there was a noun rather than a mass-classifier) to yield ''Noun&nbsp;–&nbsp;Number&nbsp;–&nbsp;Classifier''. That is to say, constructions like "horses five horses" may have been replaced by ones like "horses five {{uline|CL}}", possibly for stylistic reasons such as avoiding repetition.<ref name=Morev78-9>{{Harvnb|Morev|2000|pp=78–79}}</ref> Another reason for the appearance of count-classifiers may have been to avoid confusion or ambiguity that could have arisen from counting items using only mass-classifiers—i.e. to clarify when one is referring to a single item and when one is referring to a measure of items.<ref name=Wang172>{{Harvnb|Wang|1994|p=172}}</ref>

Historians agree that at some point in history the order of words in this construction shifted, putting the noun at the end rather than beginning, like in the present-day construction ''Number&nbsp;–&nbsp;Classifier&nbsp;–&nbsp;Noun''.<ref name=Peyraube106Morev78-9>{{Harvnb|Peyraube|1991|p=106}}; {{Harvnb|Morev|2000|pp=78–79}}</ref> According to historical linguist Alain Peyraube, the earliest occurrences of this construction (albeit with mass-classifiers, rather than count-classifiers) appear in the late portion of [[Old Chinese]] (500&nbsp;BCE to 200&nbsp;BCE). At this time, the ''Number&nbsp;–&nbsp;Mass-classifier'' portion of the ''Noun&nbsp;–&nbsp;Number&nbsp;–&nbsp;Mass-classifier'' construction was sometimes shifted in front of the noun. Peyraube speculates that this may have occurred because it was gradually reanalyzed as a [[modifier (linguistics)|modifier]] (like an adjective) for the head noun, as opposed to a simple repetition as it originally was. Since Chinese generally places modifiers before modified, as does English, the shift may have been prompted by this reanalysis. By the early part of the [[Common Era]], the nouns appearing in "classifier position" were beginning to lose their meaning and become true classifiers. Estimates of when classifiers underwent the most development vary: [[Wang Li (linguist)|Wang Li]] claims their period of major development was during the [[Han dynasty]] (206&nbsp;BCE – 220&nbsp;CE),<ref name=He3>{{Harvnb|He|2001|p=3}}</ref> whereas Liu Shiru estimates that it was the [[Northern and Southern dynasties]] period (420–589 CE),<ref>{{Harvnb|Wang|1994|pp=2, 17}}</ref> and Peyraube chooses the [[Tang dynasty]] (618–907 CE).<ref name=Peyraube111-117>{{Harvnb|Peyraube|1991|pp=111–17}}</ref> Regardless of when they developed, Wang Lianqing claims that they did not become grammatically mandatory until sometime around the 11th century.<ref name=Wang3>{{Harvnb|Wang|1994|p=3}}</ref>

Classifier systems in many nearby languages and language groups (such as [[Vietnamese language|Vietnamese]] and  the [[Tai languages]]) are very similar to the Chinese classifier system in both grammatical structure and the parameters along which some objects are grouped together. Thus, there has been some debate over which language family first developed classifiers and which ones then borrowed them—or whether classifier systems were native to all these languages and developed more through repeated [[language contact]] throughout history.<ref name=Erbaugh401Wang2>{{Harvnb|Erbaugh|1986|p=401}}; {{Harvnb|Wang|1994|p=2}}</ref>

=== Classifier words ===
Most modern count-classifiers are derived from words that originally were free-standing nouns in older varieties of Chinese, and have since been [[Grammaticalization|grammaticalized]] to become [[bound morphemes]].<ref name=Shie76Wang173>{{Harvnb|Shie|2003|p=76}}; {{Harvnb|Wang|1994|pp=113–14; 172–73}}</ref> In other words, count-classifiers tend to come from words that once had specific meaning but lost it (a process known as [[semantic bleaching]]).<ref name=Peyraube116>{{Harvnb|Peyraube|1991|p=116}}</ref> Many, however, still have related forms that work as nouns all by themselves, such as the classifier {{lang|zh|带}}&nbsp;({{lang|zh-Hant-TW|2=帶}})&nbsp;{{Transliteration|zh|dài}} for long, ribbon-like objects: the modern word {{lang|zh|带子}}&nbsp;{{Transliteration|zh|dàizi}} means "ribbon".<ref name=Shie76>{{Harvnb|Shie|2003|p=76}}</ref> In fact, the majority of classifiers can also be used as other parts of speech, such as nouns.<ref name=GaoMalt1130>{{Harvnb|Gao|Malt|2009|p=1130}}</ref> Mass-classifiers, on the other hand, are more transparent in meaning than count-classifiers; while the latter have some [[Etymology|historical meaning]], the former are still full-fledged nouns. For example, {{lang|zh|杯}}&nbsp;({{Transliteration|zh|bēi}}, cup), is both a classifier as in {{lang|zh|一{{uline|杯}}茶}}&nbsp;({{Transliteration|zh|yì {{uline|bēi}} chá}}, "a {{uline|cup}} of tea") and the word for a cup as in {{lang|zh|酒杯}}&nbsp;({{Transliteration|zh|jiǔbēi}}, "wine glass").<ref name=Chienetal92>{{Harvnb|Chien|Lust|Chiang|2003|p=92}}</ref>

{{Quote box | quote=Where do these classifiers come from? Each classifier has its own history. | source=— {{Harvtxt|Peyraube|1991|p=116}} | align=right | width=20% | bgcolor=#FFFFE0  | salign=right}}
It was not always the case that every noun required a count-classifier. In many historical varieties of Chinese, use of classifiers was not mandatory, and classifiers are rare in writings that have survived.<ref name=Erbaugh401Peyraube>{{Harvnb|Peyraube|1991}}; {{Harvnb|Erbaugh|1986|p=401}}</ref> Some nouns acquired classifiers earlier than others; some of the first documented uses of classifiers were for inventorying items, both in mercantile business and in storytelling.<ref name=Erbaugh401>{{Harvnb|Erbaugh|1986|p=401}}</ref> Thus, the first nouns to have count-classifiers paired with them may have been nouns that represent "culturally valued" items such as horses, scrolls, and intellectuals.<ref name=Erbaugh401428>{{Harvnb|Erbaugh|1986|pp=401, 403, 428}}</ref> The special status of such items is still apparent today: many of the classifiers that can only be paired with one or two nouns, such as {{lang|zh|匹}}&nbsp;{{Transliteration|zh|pǐ}} for horses<ref group=note>Today, {{lang|zh|匹}} may also be used for [[bolt (fabric)|bolts]] of cloth. See "[http://chinesenotes.com/ref_measure_words.htm List of Common Nominal Measure Words]" on ChineseNotes.com (last modified 11 January 2009; retrieved on 3 September 2009).</ref> and {{lang|zh|首}}&nbsp;{{Transliteration|zh|shǒu}} for songs or poems, are the classifiers for these same "valued" items. Such classifiers make up as much as one-third of the commonly used classifiers today.<ref name=Erbaugh403/>

{{anchor|other names}}Classifiers did not gain official recognition as a [[lexical category]] (part of speech) until the 20th century. The earliest modern text to discuss classifiers and their use was [[Ma Jianzhong]]'s 1898 ''[[Mashi Wentong|Ma's Basic Principles for Writing Clearly]]'' ({{lang|zh|马氏文通}}).<ref name=He2>{{Harvnb|He|2001|p=2}}</ref> From then until the 1940s, linguists such as Ma, Wang Li, and [[Li Jinxi]] treated classifiers as just a type of noun that express a quantity.<ref name=He3/> [[Lü Shuxiang]] was the first to treat them as a separate category, calling them "unit words" ({{lang|zh|单位词}}&nbsp;{{Transliteration|zh|dānwèicí}}) in his ''Outline of Chinese Grammar'' ({{lang|zh|中国文法要略}}) published during the 1940s, and finally 'measure words' ({{lang|zh|量词}}&nbsp;{{Transliteration|zh|liàngcí}}) in ''Grammar Studies'' ({{lang|zh|语法学习}}). He made this separation based on the fact that classifiers were semantically bleached, and that they can be used directly with a number, whereas true nouns need to have a measure word added before they can be used with a number.<ref name=He4>{{Harvnb|He|2001|p=4}}</ref> After this time, other names were also proposed for classifiers: Gao Mingkai called them 'noun helper words' ({{lang|zh|助名词}}&nbsp;{{Transliteration|zh|zhùmíngcí}}), Lu Wangdao 'counting markers' ({{lang|zh|计标}}&nbsp;{{Transliteration|zh|jìbiāo}}). The Japanese linguist Miyawaki Kennosuke called them 'accompanying words' ({{lang|zh|陪伴词}}&nbsp;{{Transliteration|zh|péibàncí}}).<ref name=He5-6>{{Harvnb|He|2001|pp=5–6}}</ref> In the {{ill|italic=y|Draft Plan for a System of Teaching Chinese Grammar|zh|暂拟汉语教学语法系统}} adopted by the [[People's Republic of China]] in 1954, Lü's measure words ({{lang|zh|量词}}&nbsp;{{Transliteration|zh|liàngcí}}) was adopted as the official name for classifiers in China.<ref name=He7>{{Harvnb|He|2001|p=7}}</ref> This remains the most common term in use today.<ref name=Li1116Hu7WangHe8/>

=== General classifiers ===
Historically, {{lang|zh|个}} {{Transliteration|zh|gè}} was not always the general classifier. Some believe it was originally a noun referring to [[bamboo]] stalks, and gradually expanded in use to become a classifier for many things with "vertical, individual, [or] upright qualit[ies]",<ref name=Erbaugh430>{{Harvnb|Erbaugh|1986|p=430}}</ref> eventually becoming a general classifier because it was used so frequently with common nouns.<ref name=Erbaugh428-30Ahrens205>{{Harvnb|Erbaugh|1986|pp=428–30}}; {{Harvnb|Ahrens|1994|p=205}}</ref> The classifier {{Transliteration|zh|gè}} is actually associated with three different [[homophonous]] characters: {{lang|zh|个}}, {{lang|zh|個}} (now the [[Traditional Chinese character|traditional-character]] equivalent of {{lang|zh|个}}), and {{lang|zh|箇}}. Historical linguist Lianqing Wang has argued that these characters actually originated from different words, and that only {{lang|zh|箇}} had the original meaning of "bamboo stalk".<ref name=Wang114-5>{{Harvnb|Wang|1994|pp=114–15}}</ref> {{lang|zh|个}}, he claims, was used as a general classifier early on, and may have been derived from the orthographically similar {{lang|zh|介}}&nbsp;{{Transliteration|zh|jiè}}, one of the earliest general classifiers.<ref name=Wang95>{{Harvnb|Wang|1994|p=95}}</ref> {{lang|zh|箇}} later merged with {{lang|zh|介}} because they were similar in pronunciation and meaning (both used as general classifiers).<ref name=Wang114-5/> Likewise, he claims that {{lang|zh|個}} was also a separate word (with a meaning having to do with "partiality" or "being a single part"), and merged with {{lang|zh|个}} for the same reasons as {{lang|zh|箇}} did; he also argues that {{lang|zh|個}} was "created", as early as the [[Han dynasty]], to supersede {{lang|zh|个}}.<ref name=Wang115-6158>{{Harvnb|Wang|1994|pp=115–16; 158}}</ref>

Historically, {{lang|zh|个}} was the only general classifier used in Chinese. The aforementioned {{lang|zh|介}}&nbsp;{{Transliteration|zh|jiè}} was being used as a general classifier before the [[Qin dynasty]] (221{{Nbsp}}BCE); it was originally a noun referring to individual items out of a string of connected shells or clothes, and eventually came to be used as a classifier for "individual" objects (as opposed to pairs or groups of objects) before becoming a general classifier.<ref name=Wang93-5>{{Harvnb|Wang|1994|pp=93–95}}</ref> Another general classifier was {{lang|zh|枚}}&nbsp;{{Transliteration|zh|méi}}, which originally referred to small twigs. Since twigs were used for counting items, {{lang|zh|枚}} became a counter word: any items, including people, could be counted as "one&nbsp;{{lang|zh|枚}}, two&nbsp;{{lang|zh|枚}}", etc. {{lang|zh|枚}} was the most common classifier in use during the [[Northern and Southern dynasties]] period (420–589 CE),<ref name=Wang155-7>{{Harvnb|Wang|1994|pp=155–7}}</ref> but today is no longer a general classifier, and is only used rarely, as a specialized classifier for items such as pins and badges.<ref name=Erbaugh428>{{Harvnb|Erbaugh|1986|p=428}}</ref> Kathleen Ahrens has claimed that {{lang|zh|隻}} ({{Transliteration|zh|zhī}} in Mandarin and {{lang|nan-Latn|chiah}} in [[Taiwanese Hokkien]]), the classifier for animals in [[Standard Chinese|Mandarin]], is another general classifier in Taiwanese and may be becoming one in the Mandarin spoken in Taiwan.<ref name=Ahrens206>{{Harvnb|Ahrens|1994|p=206}}</ref>

=== Topological variation ===
Northern dialects tend to have fewer classifiers than southern ones. {{zhi|c=個}}&nbsp;{{Transliteration|zh|ge}} is the only classifier found in the [[Dungan language]]. All nouns could have just one classifier in some dialects, such as [[Shanghainese]] Wu, [[Jin Chinese]] in Shanxi, and dialects spoken in [[Shandong]]. Some dialects such as [[Northern Min]], certain [[Xiang Chinese|Xiang dialects]], [[Hakka Chinese|Hakka dialects]], and some [[Yue dialects]] use {{zhi|c=隻}} for the noun referring to people, rather than {{zhi|c=個}}.<ref>{{cite book|author1=Graham Thurgood|author2=Randy J. LaPolla|editor=Graham Thurgood, Randy J. LaPolla|edition=illustrated|publisher=Psychology Press|year=2003|page=85|isbn=0-7007-1129-5|quote=In general, the Southern dialects have a greater number of classifiers than the Northern. The farther north one travels, the smaller the variety of classifiers found. In Dunganese, a Gansu dialect of Northern Chinese spoken in Central Asia, only one classifier, 個 [kə], is used; and this same classifier has almost become the cover classifier for all nouns in Lánzhou of Gansu too. The tendency to use one general classifier for all nouns is also found to a greater or lesser extent in many Shanxi dialects, some Shandong dialects, and even the Shanghai dialect of Wu and Standard Mandarin (SM). The choice of classifiers for individual nouns is particular to each dialect. For example, although the preferred classifier across dialects for 'human being' is 個 and its cognates, 隻 in its dialect forms is widely used in the Hakka and Yue dialects of Guangxi and western Guangdong provinces as well as in the Northern Min dialects and some Xiang dialects in Hunan.|title=The Sino-Tibetan languages|volume=3 |series=Routledge language family|url=https://books.google.com/books?id=5MeWSTQ7F44C&dq=wugang+dialect&pg=PA85|access-date=2012-03-10}}</ref>
