Noun

{{Short description|Part of speech that names an object or set of objects}}
{{Other uses}}

In [[grammar]], a '''noun''' is a word that represents a concrete or abstract thing, such as living creatures, places, actions, qualities, states of existence, and ideas. A noun may serve as an [[Object (grammar)|object]] or [[Subject (grammar)|subject]] within a phrase, clause, or sentence.<ref>{{cite web|title=Noun|year=2024|publisher=Encyclopedia Britannica|url=https://www.britannica.com/dictionary/noun#:~:text=Britannica%20Dictionary%20definition%20of%20NOUN%20%5Bcount%5D%20%3A%20a,common%20noun%2C%20count%20noun%2C%20noncount%20noun%2C%20proper%20noun/}}</ref><ref group=note>Example nouns for:
* Living creatures (including people, alive, dead, or imaginary): ''mushrooms, dogs, [[Afro-Caribbean]]s, rosebushes, [[Mandela]], bacteria, [[Klingons]]'', etc.
* Physical objects: ''hammers, pencils, Earth, guitars, atoms, stones, boots, shadows'', etc.
* Places: ''closets, temples, rivers, Antarctica, houses, [[Uluru]], [[utopia]]'', etc.
* Actions of individuals or groups: ''swimming, exercises, cough, explosions, flight, electrification, embezzlement'', etc.
* Physical qualities: ''colors, lengths, porosity, weights, roundness, symmetry, solidity,'' etc.
* Mental or bodily states: ''jealousy, sleep, joy, headache, confusion'', etc.</ref> 

In [[linguistics]], nouns constitute a lexical category ([[Part of speech|part of speech]]) defined according to how its members combine with members of other lexical categories. The [[Syntax|syntactic]] occurrence of nouns differs among languages. 

In English, prototypical nouns are [[Proper noun|common nouns or proper nouns]] that can occur with [[determiners]], [[article (grammar)|articles]] and [[adjective|attributive adjectives]], and can function as the [[head (linguistics)|head]] of a [[noun phrase]]. According to traditional and popular classification, [[pronoun]]s are distinct from nouns, but in much modern theory they are considered a subclass of nouns.<ref>Huddleston, Rodney, and Geoffrey K. Pullum. ''The Cambridge Grammar of the English Language.'' Cambridge: Cambridge University Press, 2002, p.&nbsp;327.</ref>  Every language has various linguistic and grammatical distinctions between nouns and [[verb]]s.<ref>{{cite book|title=Language Unlimited: The science behind our most creative power |url=https://www.google.com/books/edition/Language_Unlimited/q7SmDwAAQBAJ?hl=en&gbpv=1&pg=PA78 |author=David Adger |author-link1=David Adger |location=Oxford|publisher=Oxford University Press|year=2019|isbn=978-0-19-882809-9|page=78}}</ref>

== History <span id="Substantive as a word for noun"></span>==
{{hatnote|See also [[Part of speech#History|History of parts of speech]]}}
[[Word class]]es (parts of speech) were described by [[Sanskrit]] grammarians from at least the 5th century BC. In [[Yāska]]'s ''[[Nirukta]]'', the noun (''nāma'') is one of the four main categories of words defined.<ref name=Matilal>[[Bimal Krishna Matilal]], ''The word and the world: India's contribution to the study of language'', 1990 (Chapter 3)</ref>

The [[Ancient Greek]] equivalent was ''ónoma'' (ὄνομα), referred to by [[Plato]] in the [[Cratylus (dialogue)|''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".<ref>{{L&S|nomen|nōmen|ref}}; {{LSJ|o/noma|ὄνομα|ref}}</ref> The English word ''noun'' is derived from the Latin term, through the [[Anglo-Norman language|Anglo-Norman]] ''nom'' (other forms include ''nomme'', and ''noun'' itself).

The word classes were defined partly by the grammatical [[morphology (linguistics)|forms]] that they take. In Sanskrit, Greek, and Latin, for example, nouns are categorized by [[grammatical gender|gender]] and inflected for [[grammatical case|case]] and [[grammatical number|number]]. Because [[adjective]]s share these three [[grammatical category|grammatical categories]], adjectives  typically were placed in the same class as nouns.

Similarly, the Latin term ''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 simply ''substantives'' and ''adjectives''). (The word ''[[nominal (linguistics)|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 [[noun phrase]]s (multiword units that are sometimes called ''noun equivalents'').<ref name="CMOS">{{Citation |author = Chicago Manual of Style |author-link = The Chicago Manual of Style |title = The Chicago Manual of Style |section = 5.10: Noun-equivalents and substantives |publisher = [[University of Chicago Press]] |url=http://www.chicagomanualofstyle.org/16/ch05/ch05_sec010.html |postscript=.}}</ref> It can also be used as a counterpart to ''attributive'' when distinguishing between a noun being used as the [[head (linguistics)|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''.

== Examples ==
* The ''cat'' sat on the ''chair''.
* Please hand in your ''assignments'' by the ''end'' of the ''week''.
* ''Cleanliness'' is next to ''godliness''.
* ''Plato'' was an influential ''philosopher'' in ancient ''Greece''.
* Revel the ''night'', rob, murder, and commit&nbsp;/&nbsp;The oldest ''sins'' the newest ''kind'' of ''ways''? Henry IV Part 2, act 4 scene 5.

A noun can co-occur with an [[article (grammar)|article]] or an [[adjective|attributive adjective]]. Verbs and adjectives cannot. In the following, an asterisk (*) in front of an example means that this example is ungrammatical.

* ''the name'' (''name'' is a noun: can co-occur with a definite article ''the'')
* ''*the baptise'' (''baptise'' is a verb: cannot co-occur with a definite article)
* ''constant circulation'' (''circulation'' is a noun: can co-occur with the attributive adjective ''constant'')
* ''*constant circulate'' (''circulate'' is a verb: cannot co-occur with the attributive adjective ''constant'')
* ''a fright'' (''fright'' is a noun: can co-occur with the indefinite article ''a'')
* ''*an afraid'' (''afraid'' is an adjective: cannot co-occur with the article ''a'')
* ''terrible fright'' (the noun ''fright'' can co-occur with the adjective ''terrible'')
* ''*terrible afraid'' (the adjective ''afraid'' cannot co-occur with the adjective ''terrible'')

== Characterization and definition ==

Nouns have sometimes been characterized in terms of the [[Grammatical category|grammatical categories]] by which they may be varied (for example [[Gender (linguistics)|gender]], [[Case (linguistics)|case]], and [[Number (linguistics)|number]]). Such definitions tend to be language-specific, since different languages may apply different categories.

Nouns are frequently defined, particularly in informal contexts, in terms of their [[semantics|semantic]] properties (their meanings). Nouns are described as words that refer to a ''person'', ''place'', ''thing'', ''event'', ''substance'', ''quality'', ''quantity'', etc., but this manner of definition has been criticized as uninformative.<ref name=jackendoff>{{cite book|last=Jackendoff|first=Ray|author-link=Ray Jackendorff|date=2002|title=Foundations of language: brain, meaning, grammar, evolution|publisher=Oxford University Press|chapter-url=http://npu.edu.ua/!e-book/book/djvu/A/iif_kgpm_Foundations%20of%20Language.pdf |archive-url=https://ghostarchive.org/archive/20221009/http://npu.edu.ua/!e-book/book/djvu/A/iif_kgpm_Foundations%20of%20Language.pdf |archive-date=2022-10-09 |url-status=live|isbn= 0-19-827012-7|chapter=§5.5 Semantics as a generative system}}</ref>

Several English nouns lack an intrinsic [[referent]] of their own: ''behalf'' (as in ''on behalf of''), ''dint'' (''by dint of''), and ''sake'' (''for the sake of'').<ref>pages 218 and 225, and elsewhere in {{cite book|last=Quine|first=Willard Van Orman|title=Word and Object|location=Cambridge, Massachusetts|publisher=MIT Press|date=2013|orig-year=1960 print|chapter=7 Ontic Decision|pages=215–254|author-link=Willard Van Orman Quine}}</ref> Moreover, other parts of speech may have reference-like properties: the verbs ''to rain'' or ''to mother'', or adjectives like ''red''; and there is little difference between the adverb ''gleefully'' and the [[preposition and postposition|prepositional phrase]] ''with glee''.<ref group=note> Idioms often include nouns in a way that may be independent of any nominal meaning they may have: in ''rock and roll'' there is no reference to any "rock" or any "roll"; ''lock, stock, and barrel'' is a [[dead metaphor]] that refers only to a figurative sense of a ''lock'' or ''stock'' or ''barrel''. See [[hendiadys]] and [[hendiatris]].</ref>

A [[Functional linguistics|functional]] approach defines a noun as a word that can be the head of a nominal phrase, i.e., a phrase with referential function, without needing to go through morphological transformation.<ref name=rijkhoff2022>{{cite book

== Classification ==
Nouns can have a number of different properties and are often sub-categorized based on various of these criteria, depending on their occurrence in a language. Nouns may be classified according to [[morphology (linguistics)|morphological]] properties such as which [[prefix]]es or [[suffix]]es they take, and also their relations in [[syntax]]&nbsp;– how they combine with other words and expressions of various types. 

Many such classifications are language-specific, given the obvious differences in syntax and morphology. In English for example, 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 could not apply in [[Russian language|Russian]], which has no definite articles.

=== Gender ===
{{main|Grammatical gender}}

In some languages common and proper nouns have grammatical gender, typically masculine, feminine, and neuter. The gender of a noun (as well as its number and case, where applicable) will often require [[agreement (linguistics)|agreement]] in words that modify or are used along with it. In [[French language|French]] for example, the singular form of the definite article is ''le'' for masculine nouns and ''la'' for feminine; adjectives and certain verb forms also change (sometimes with the simple addition of {{nowrap|''-e''}} for feminine). Grammatical gender often correlates with the form of the noun and the inflection pattern it follows; for example, in both [[Italian language|Italian]] and [[Romanian language|Romanian]] most nouns ending in&nbsp;''-a'' are feminine. Gender can also correlate with the [[sex]] or [[social gender]] of the noun's referent, particularly in the case of nouns denoting people (and sometimes animals), though with exceptions (the feminine French noun ''personne'' can refer to a male or a female person).

In Modern English, even common nouns like ''hen'' and ''princess'' and proper nouns like ''Alicia'' do not have grammatical gender (their femininity has no relevance in syntax), though they denote persons or animals of a specific sex. The gender of a pronoun must be appropriate for the item referred to: "The ''girl'' said the ''ring'' was from ''her'' new ''boyfriend'', but ''he'' denied ''it'' was from ''him''" (three nouns; and three gendered pronouns: or four, if this ''her'' is counted as a [[English possessive#Pronouns|possessive pronoun]]).

=== Proper and common nouns ===<!-- This section is linked from [[Czech language]] -->
{{anchor|Proper nouns and common nouns|reason=Old, redundant section heading; has incoming links to it.}}
{{main|Proper noun}}

A ''proper noun'' (sometimes called a ''proper name'', though the two terms normally have different meanings) is a noun that represents a unique entity (''India'', ''[[Pegasus]]'', ''[[Jupiter]]'', ''[[Confucius]]'', ''[[Pequod (Moby-Dick)|Pequod]]'') – as distinguished from ''common nouns'' (or '''appellative nouns'''), which describe a class of entities (''country'', ''animal'', ''planet'', ''person'', ''ship'').<ref>{{harvnb|Lester|Beason|2005| page = 4}}</ref> In Modern English, most proper nouns – unlike most common nouns – are capitalized regardless of context (''Albania'', ''Newton'', ''Pasteur'', ''America''), as are many of the forms that are derived from them (the common noun in "he's an ''Albanian''"; the adjectival forms in "he's of ''Albanian'' heritage" and "''Newtonian'' physics", but not in "''pasteurized'' milk"; the second verb in "they sought to ''Americanize'' us").

=== Countable nouns and mass nouns ===
{{Main|Count noun|Mass noun}}

''Count nouns'' or ''countable nouns'' are common nouns that can take a [[plural]], can combine with [[numeral system|numerals]] or counting [[Quantifiers (linguistics)|quantifiers]] (e.g., ''one'', ''two'', ''several'', ''every'', ''most''), and can take an indefinite article such as ''a'' or ''an'' (in languages that have such articles). Examples of count nouns are ''chair'', ''nose'', and ''occasion''.

''Mass nouns'' or ''uncountable'' (''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, the forms ''a furniture'' and ''three furnitures'' are not used – even though ''pieces'' of furniture can be counted. The distinction between mass and count nouns does not primarily concern their corresponding referents but more how the nouns ''present'' those entities.<ref>[[Manfred Krifka|Krifka, Manfred]]. 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.</ref><ref>{{harvnb|Borer|2005}}</ref>

Many nouns have both countable and uncountable uses; for example, ''soda'' is countable in "give me three sodas", but uncountable in "he likes soda".

=== Collective nouns ===
{{Main|Collective noun}}

''Collective nouns'' are nouns that – even when they are treated in their morphology and syntax as [[Grammatical number|singular]] – refer to ''groups'' consisting of more than one individual or entity. Examples include ''committee'', ''government'', and ''police''. In English these nouns may be followed by a singular or a plural verb and referred to by a singular or plural pronoun, the singular being generally preferred when referring to the body as a unit and the plural often being preferred, especially in British English, when emphasizing the individual members.<ref name="Gowers 2014">{{harvnb|Gowers|2014|pages=189–190}}</ref> Examples of acceptable and unacceptable use given by Gowers in ''Plain Words'' include:<ref name="Gowers 2014"/>
{{block indent|"A committee ''was'' appointed to consider this subject." (singular)}}
{{block indent|"The committee ''were'' unable to agree." (plural)}}
{{block indent|* "The committee were of one mind when I sat in on them." (unacceptable use of plural)}}

=== Concrete nouns and abstract nouns ===
{{Further|Physical body|Abstract object}}
{{Unreferenced section|date=January 2023}}
''Concrete nouns'' refer to [[physical bodies|physical entities]] that can, in principle at least, be observed by at least one of the [[sense]]s (''chair'', ''apple'', ''Janet'', ''atom''), as items supposed to exist in the physical world. ''Abstract nouns'', on the other hand, refer to [[abstract object]]s: ideas or concepts (''justice'', ''anger'', ''solubility'', ''duration'').

Some nouns have both concrete and abstract meanings: ''art'' usually refers to something abstract ("Art is important in human culture"), but it can also refer to a concrete item ("I put my daughter's art up on the fridge"). A noun might have a literal (concrete) and also a figurative (abstract) meaning: "a brass ''key''" and "the ''key'' to success"; "a ''block'' in the pipe" and "a mental ''block''". Similarly, some abstract nouns have developed etymologically by figurative extension from literal roots (''drawback'', ''fraction'', ''holdout'', ''uptake'').

Many abstract nouns in English are formed by adding a suffix (''-ness'', ''-ity'', ''-ion'') to adjectives or verbs (''happiness'' and ''serenity'' from the adjectives ''happy'' and ''serene''; ''circulation'' from the verb ''circulate'').

=== Alienable vs. inalienable nouns ===
{{Main|Inalienable possession}}
Illustrating the wide range of possible classifying principles for nouns, the [[Awa language (Papua New Guinea)|Awa language]] of [[Papua New Guinea]]<ref>{{cite web |url=https://glossary.sil.org/term/inalienable-noun |title=Inalienable Noun |author=<!--Not stated--> |date=3 December 2015 |publisher=[[SIL International]] |access-date= 6 February 2020}}</ref> regiments nouns according to how ''ownership'' is assigned: as alienable possession or [[Inalienable possession|inalienable]] possession. An alienably possessed item (a tree, for example) can exist even without a possessor. But inalienably possessed items are necessarily associated with their possessor and are referred to differently, for example with nouns that function as kin terms (meaning "father", etc.), body-part nouns (meaning "shadow", "hair", etc.), or part–whole nouns (meaning "top", "bottom", etc.).

== Noun phrases ==
{{main|Noun phrase}}

A noun phrase (or '''NP''') is a phrase usually [[Head (linguistics)|headed]] by a common noun, a proper noun, or a pronoun. The head may be the only constituent, or it may be modified by [[determiner]]s and [[adjective]]s. For example, "The dog sat near Ms Curtis and wagged its tail" contains three NPs: ''the dog'' (subject of the verbs ''sat'' and ''wagged''); ''Ms Curtis'' (complement of the preposition ''near''); and ''its tail'' (object of ''wagged''). "You became their teacher" contains two NPs: ''you'' (subject of ''became''); and ''their teacher''.<ref group=note>In this position ''their teacher'' would be analysed variously under different linguistic theories. For example, some would classify it as a "predicate nominal over the subject" (as in the article [[Predicative expression]]); but all would agree that it is not an object since ''became'' is not [[Transitive verb|transitive]]. Traditionally, and very commonly in mainstream linguistic analysis, it is classified as a complement or ''predicative complement'' (PC); see extended treatment in Chapter&nbsp;4 ("The clause: complements") of Huddleston and Pullum (2002), pp.&nbsp;213–321: for example in §5.1 at p.&nbsp;253, where the NP ''a minister'' is taken as a PC in "Ed became <u>a minister</u>" contrasting with its role as an object (O) in "Ed attacked <u>a minister</u>".</ref>

==Nouns in relation to other word classes==
===Pronouns===
{{main|Pronoun}}

Nouns and noun phrases can typically be replaced by [[pronoun]]s, such as ''he, it, she, they, which, these'', and ''those'', to avoid repetition or explicit identification, or for other reasons (but as noted earlier, current theory often classifies pronouns as a subclass of nouns parallel to ''prototypical nouns''). For example, in the sentence "Gareth thought she was weird", the word ''she'' is a pronoun that refers to a person just as the noun ''Gareth'' does. The word ''one'' can replace parts of noun phrases, and it sometimes stands in for a noun. An example is given below:

{{block indent|John's car is newer than ''the one'' that Bill has.}}

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''.

{{block indent|This new car is cheaper than ''that one''.}}

===Nominalization===
{{main|Nominalization}}
Nominalization is a process whereby a word that belongs to another part of speech comes to be used as a noun. This can be a way to create new nouns, or to use other words in ways that resemble nouns. In French and Spanish, for example, adjectives frequently act as nouns referring to people who have the characteristics denoted by the adjective. This sometimes happens in English as well, as in the following examples:

{{block indent|This legislation will have the most impact on the ''poor''.}}
{{block indent|The race is not to the ''swift'', nor the battle to the ''powerful''.}}
{{block indent|The Socialist ''International'' is a worldwide association of political parties.}}
