A noun (from Latin nōmen, literally name) is a word that functions as the name of a specific object or set of objects, such as living creatures, places, actions, qualities, states of existence, or ideas.Example nouns for:
However, noun is not a semantic category, so that it cannot be characterized in terms of its meaning. Thus, actions and states of existence can also be expressed by verbs, qualities by adjectives, and places by adverbs. Linguistics, a noun is a member of a large, open part of speech whose members can occur as the main word in the subject of a clause, the object of a verb, or the object of a preposition.Loos, Eugene E., et al. 2003. Glossary of linguistic terms: What is a noun?
Lexical categories (parts of speech) are defined in terms of the ways in which their members combine with other kinds of expressions. The syntactic rules for nouns differ from language to language. In English language, nouns are those words which can occur with articles and adjective and can function as the head of a noun phrase. "As far as we know, every language makes a grammatical distinction that looks like a noun verb distinction."
The Ancient Greek equivalent was ónoma (ὄνομα), referred to by Plato in the Cratylus dialog, and later listed as one of the eight parts of speech in The Art of Grammar, attributed to Dionysius Thrax (2nd century BC). The term used in Latin grammar was nōmen. All of these terms for "noun" were also words meaning "name".; The English word noun is derived from the Latin term, through the Anglo-Norman noun.
The word classes were defined partly by the grammatical forms that they take. In Sanskrit, Greek and Latin, for example, nouns are categorized by gender and inflected for grammatical case and number. Because share these three grammatical categories, adjectives are placed in the same class as nouns.
Similarly, the Latin nōmen includes both nouns (substantives) and adjectives, as originally did the English word noun, the two types being distinguished as nouns substantive and nouns adjective (or substantive nouns and adjective nouns, or short substantives and adjectives). (The word nominal is now sometimes used to denote a class that includes both nouns and adjectives.)
Many European languages use a cognate of the word substantive as the basic term for noun (for example, Spanish sustantivo, "noun"). Nouns in the dictionaries of such languages are demarked by the abbreviation s. or sb. instead of n., which may be used for proper nouns or neuter nouns instead. In English, some modern authors use the word substantive to refer to a class that includes both nouns (single words) and (multiword units, also called noun equivalents). It can also be used as a counterpart to attributive when distinguishing between a noun being used as the head (main word) of a noun phrase and a noun being used as a noun adjunct. For example, the noun knee can be said to be used substantively in my knee hurts, but attributively in the patient needed knee replacement.
Nouns are frequently defined, particularly in informal contexts, in terms of their semantics properties (their meanings). Nouns are described as words that refer to a person, place, thing, event, substance, quality, quantity, etc. However this type of definition has been criticized by contemporary linguists as being uninformative.
There have been offered several examples of English-language nouns which do not have any reference: drought, enjoyment, finesse, behalf (as found in on behalf of), dint ( in dint of), and sake ( for the sake of).pages 218, 225 and elsewhere in Moreover, there may be a relationship similar to reference in the case of other parts of speech: the verbs to rain or to mother; many adjectives, like red; and there is little difference between the adverb gleefully and the noun-based phrase with glee.Nouns occur in idioms with no meaning outside the idiom: rock and roll does not describe two different things named by rock and by roll; someone who falls for something lock, stock and barrel does not fall for something lock, for stock, and for barrel; a trick using smoke and mirrors does not separate into the effect of smoke and each mirror. See hendiadys and hendiatris.
There are placeholder names, such as the legal fiction reasonable person (whose existence is not in question), an experimental artifact, or Anthropomorphism such as gremlin.
Linguistics often prefer to define nouns (and other lexical categories) in terms of their formal properties. These include morphological information, such as what or they take, and also their syntax – how they combine with other words and expressions of particular types. Such definitions may nonetheless still be language-specific since syntax as well as morphology varies between languages. For example, in English, it might be noted that nouns are words that can co-occur with definite articles (as stated at the start of this article), but this would not apply in Russian language, which has no definite articles.
There have been several attempts, sometimes controversial, to produce a stricter definition of nouns on a semantic basis.
Mass nouns or uncountable (or non-count) nouns differ from count nouns in precisely that respect: they cannot take plurals or combine with number words or the above type of quantifiers. For example, it is not possible to refer to a furniture or three furnitures. This is true even though the pieces of furniture comprising furniture could be counted. Thus the distinction between mass and count nouns should not be made in terms of what sorts of things the nouns refer to, but rather in terms of how the nouns present these entities.Manfred Krifka. 1989. "Nominal Reference, Temporal Constitution and Quantification in Event Semantics". In R. Bartsch, J. van Benthem, P. von Emde Boas (eds.), Semantics and Contextual Expression, Dordrecht: Foris Publication.
Many nouns have both countable and uncountable uses; for example, soda is countable in "give me three sodas", but uncountable in "he likes soda".
Some abstract nouns developed etymologically by figurative extension from literal roots. These include drawback, fraction, holdout and uptake. Similarly, some nouns have both abstract and concrete senses, with the latter having developed by figurative extension from the former. These include view, filter, structure and key.
In English, many abstract nouns are formed by adding a suffix ( -ness, -ity, -ion) to adjectives or verbs. Examples are happiness (from the adjective happy), circulation (from the verb circulate) and serenity (from the adjective serene).
But one can also stand in for larger parts of a noun phrase. For example, in the following example, one can stand in for new car.
