Mass noun

Not to be confused with Collective noun.

Template:ExamplesSidebar In linguistics, a mass noun (also uncountable noun or non-count noun) is a common noun that presents entities as an unbounded mass. Given that different languages have different grammatical resources, the actual test for which nouns are mass nouns may vary from language to language. In English, mass nouns are characterized by the fact that they cannot be directly modified by a numeral without specifying a unit of measurement, and that they cannot combine with an indefinite article (a(n)). Mass nouns combine with expressions like too much ("too much water"), while count nouns don't (*"too much chair(s)").

Relating grammatical number to physical discreteness

In English (and in many other languages), there is a tendency for nouns referring to liquids (water, juice), powders (sugar, sand), or substances (metal, wood) to be mass nouns, and for nouns referring to objects or people to be count nouns. This is not a hard-and-fast rule, however; such mass nouns as furniture and cutlery, which represent more easily quantified objects, show that the mass/count distinction should be thought of as a property of the terms themselves, rather than as a property of their referents. For example, the same set of chairs can be referred to as "seven chairs" and as "furniture"; though both chair and furniture are referring to the same thing, the former is a count noun and the latter a mass noun.

For another illustration of the principle that the count/non-count distinction lies not in an object but rather in the expression that refers to it, consider the English words "fruit" and "vegetables". The objects that these words describe are, objectively speaking, similar (that is, they're all edible plant parts); yet the word "fruit" is (usually) non-count, whereas "vegetables" is a plural count form. One can see that the difference is in the language, not in the reality of the objects. Meanwhile, German has a general word for "vegetables" that, like English "fruit", is (usually) non-count: das Gemüse. British English has a slang word for "vegetables" that acts the same way: "veg" [rhymes with "edge"].

The work of logicians like Godehard Link and Manfred Krifka established that the mass/count distinction can be given a precise, mathematical definition in terms of quantization and cumulativity.

Cumulativity and mass nouns

An expression P has cumulative reference if and only if for any X and Y:

• If X can be described as P and Y can be described as P, as well, then the sum of X and Y can also be described as P.

Consider, for example cutlery: If one collection of cutlery is combined with another, we still have "cutlery." Similarly, if water is added to water, we still have "water." But if a chair is added to another, we don't have "a chair," but rather two chairs. Thus the nouns "cutlery" and "water" have cumulative reference, while the expression "a chair" does not. (The expression "chairs", however, does.) The distinction between nouns that have cumulative reference and those that do not can be seen to correspond to the one between mass and count nouns.

Multiple senses for one noun

Many English count nouns can be used as mass nouns, and in these cases, they take on cumulative reference. For example, one may say that "there's apple in this sauce," and then apple has cumulative reference, and, hence, is used as a mass noun. Conversely, "fire" is generally a mass noun, but "a fire" refers to a discrete entity, and does not satisfy the criterion for cumulative reference. One may say that mass nouns that are used as count nouns are "countified" and that count ones that are used as mass nouns are "massified." Some mass nouns can't easily be countified, and some count nouns are hard to massify. For example the count noun "house" is difficult to use as mass, and the mass noun "cutlery" is hard to countify:

• Bad: *There's house on the road. (bad even if we consider situation of war)
• Bad: *There's a cutlery on the table. (bad even if there's just one fork on the table)

In some languages, such as Chinese and Japanese, all nouns have been claimed to be effectively mass nouns and require a measure word to use.

The much-or-many and less-or-fewer distinctions

Another difference between mass and count nouns is the distinction between the words much and many and between less and fewer.

"We have too much furniture." (mass)

"We have too many chairs." (count)

"We used to have less furniture." (mass)

"We used to have fewer chairs." (count)

However, many English speakers use less for both types; in recent years many supermarkets have been criticised for their signs above checkouts reading "10 items or less", as the standard grammatical form would be "10 items or fewer": "items" is a count noun, and a mass noun cannot be given a number in any case. In American English in particular, "less" is used more commonly than "fewer" to describe count nouns, although this usage is often considered incorrect. Additionally, in casual speech, a construction like "10 objects or less" isn't typically heard; "less than 10 objects" is far more common. Constructions such as "10 or less of the objects" are still pervasive, however. Regardless, even in American English, this usage is frowned upon, and is typically considered an idiosyncratic, rather than dialectical, variation.

Confounding of collective noun and mass noun

There is often confusion about the two different concepts of collective noun and mass noun. Generally, collective nouns are not mass nouns, but rather are a special subset of count nouns. However, the term "collective noun" is often used to mean "mass noun" (even in some dictionaries), because users confound two different kinds of verb number invariability: (a) that seen with mass nouns such as "water" or "furniture", with which only singular verb forms are used because the constituent matter is grammatically nondiscrete (although it may ["water"] or may not ["furniture"] be etically nondiscrete); and (b) that seen with collective nouns, which is the result of the metonymical shift between the group and its (both grammatically and etically) discrete constituents.

Some words, including "mathematics" and "physics", have developed true mass-noun senses despite having grown from count-noun roots.
