Editing Measure word (section)

==Description==
Measure words denote a unit of measurement and are used with [[mass noun]]s (uncountable nouns), and in some cases also with [[count noun]]s. For instance, in [[English language|English]], ''{{linktext|mud}}'' is a mass noun and thus one cannot say "three muds", but one can say "three <u>drops</u> of mud", "three <u>pails</u> of mud", etc. In these examples, ''drops'' and ''pails'' function as measure words. One can also say "three <u>pails</u> of shells"; in this case the measure word ''pails'' accompanies a count noun (''shells'').

The term ''measure word'' is also sometimes used to refer to numeral classifiers, which are used with count nouns in some languages. For instance, in English no extra word is needed when saying "three people", but in many [[Languages of East Asia|East Asian languages]] a numeral classifier is added, just as a measure word is added for uncountable nouns in English. For example:

{{columns-start}}
{{fs interlinear |lang=zh |italics2=no |italics3=yes |indent=2
|一 只 狗 |c1=(simplified)
|一 隻 狗 |c2=(traditional)
|yī zhī gǒu
|one [measure-word] dog
|'one dog'}}
{{column}}
{{fs interlinear |lang=zh |italics2=no |italics3=yes |indent=2
|三 只 狗 |c1=(simplified)
|三 隻 狗 |c2=(traditional)
|sān zhī gǒu
|three [measure-word] dog
|'three dogs'}}
{{columns-end}}

There are numerous Chinese measure words, and nouns differ in what measure words they can use. While many linguists maintain a distinction between measure words and numeral classifiers, the terms are sometimes used interchangeably.<ref>{{Cite book |author-link1=James Tai | last=Tai | first=James H.-Y. | year=1994 | chapter=Chinese classifier systems and human categorization | editor1=William S.-Y.

The corresponding Chinese term is {{Lang|zh-Latn-pinyin|liàngcí}} ({{Zh|s=量词|t=量詞|p=}}), which can be directly translated as "quantity word".

Most measure words in English correspond to [[units of measurement]] or containers, and are themselves count nouns rather than [[grammatical particle]]s:
*one ''quart'' of water
*three ''cups'' of coffee
*four ''kernels'' of corn, three ''ears'' of corn,  two ''bushels'' of corn

Though similar in construction, fractions are not measure words. For example, in "seven-eighths of an apple" the fraction acts as a noun. Compare that to "seven slices of apple" where "apple" is a mass noun and does not require the article "an". Combining the two, e.g. "seven-eighths of a slice of apple", makes it clear the fraction must be a noun referring to a part of another countable noun.

In many languages, including the East Asian languages referred to above, the analogous constructions do not include any equivalent of the English ''of''. In [[German language|German]], for example, ''ein Glas Bier'' means "a glass [of] beer". This is interesting since both languages are [[West Germanic languages]], making them closely related to each other. However, the equivalent of the English ''of'' is common in [[Romance languages]] such as "a glass of beer":
: {{langx|es|un vaso <u>de</u> cerveza}}
: {{langx|fr|un verre <u>de</u> bière}}
: {{langx|pt|um copo <u>de</u> cerveja}}
