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 or subject within a phrase, clause, or sentence. [1] [note 1]
In linguistics, nouns constitute a lexical category (part of speech) defined according to how its members combine with members of other lexical categories. The syntactic occurrence of nouns differs among languages.
In English, prototypical nouns are common nouns or proper nouns that can occur with determiners, articles and attributive adjectives, and can function as the head of a noun phrase. According to traditional and popular classification, pronouns are distinct from nouns, but in much modern theory they are considered a subclass of nouns. [2] Every language has various linguistic and grammatical distinctions between nouns and verbs. [3]
Word classes (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. [4]
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". [5] The English word noun is derived from the Latin term, through the Anglo-Norman nom (other forms include nomme, and noun itself).
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 case and number. Because adjectives share these three 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 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 phrases (multiword units that are sometimes called noun equivalents). [6] 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.
A noun can co-occur with an article or an attributive adjective. Verbs and adjectives cannot. In the following, an asterisk (*) in front of an example means that this example is ungrammatical.
Nouns have sometimes been characterized in terms of the grammatical categories by which they may be varied (for example gender, case, and 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 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. [7]
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). [8] 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 prepositional phrase with glee. [note 2]
A 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. [9] [10]
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 morphological properties such as which prefixes or suffixes they take, and also their relations in syntax – 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, which has no definite articles.
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 in words that modify or are used along with it. In 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 -e for feminine). Grammatical gender often correlates with the form of the noun and the inflection pattern it follows; for example, in both Italian and Romanian most nouns ending in -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 possessive pronoun).
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 ) – as distinguished from common nouns (or appellative nouns), which describe a class of entities (country, animal, planet, person, ship). [11] 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").
Count nouns or countable nouns are common nouns that can take a plural, can combine with numerals or counting 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. [12] [13]
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 are nouns that – even when they are treated in their morphology and syntax as 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. [14] Examples of acceptable and unacceptable use given by Gowers in Plain Words include: [14]
Concrete nouns refer to physical entities that can, in principle at least, be observed by at least one of the senses (chair, apple, Janet, atom), as items supposed to exist in the physical world. Abstract nouns, on the other hand, refer to abstract objects: 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).
Illustrating the wide range of possible classifying principles for nouns, the Awa language of Papua New Guinea [15] regiments nouns according to how ownership is assigned: as alienable possession or 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.).
A noun phrase (or NP) is a phrase usually headed by a common noun, a proper noun, or a pronoun. The head may be the only constituent, or it may be modified by determiners and adjectives. 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. [note 3]
Nouns and noun phrases can typically be replaced by pronouns, 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:
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.
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:
In linguistics, declension is the changing of the form of a word, generally to express its syntactic function in the sentence, by way of some inflection. Declensions may apply to nouns, pronouns, adjectives, adverbs, and determiners to indicate number, case, gender, and a number of other grammatical categories. Meanwhile, the inflectional change of verbs is called conjugation.
In linguistics, a grammatical gender system is a specific form of a noun class system, where nouns are assigned to gender categories that are often not related to the real-world qualities of the entities denoted by those nouns. In languages with grammatical gender, most or all nouns inherently carry one value of the grammatical category called gender. The values present in a given language, of which there are usually two or three, are called the genders of that language.
A verb is part of speech that in syntax generally conveys an action, an occurrence, or a state of being. In the usual description of English, the basic form, with or without the particle to, is the infinitive. In many languages, verbs are inflected to encode tense, aspect, mood, and voice. A verb may also agree with the person, gender or number of some of its arguments, such as its subject, or object. In English, three tenses exist: present, to indicate that an action is being carried out; past, to indicate that an action has been done; future, to indicate that an action will be done, expressed with the auxiliary verb will or shall.
An adjective is a word that describes or defines a noun or noun phrase. Its semantic role is to change information given by the noun.
English grammar is the set of structural rules of the English language. This includes the structure of words, phrases, clauses, sentences, and whole texts.
French grammar is the set of rules by which the French language creates statements, questions and commands. In many respects, it is quite similar to that of the other Romance languages.
The plural, in many languages, is one of the values of the grammatical category of number. The plural of a noun typically denotes a quantity greater than the default quantity represented by that noun. This default quantity is most commonly one. Therefore, plurals most typically denote two or more of something, although they may also denote fractional, zero or negative amounts. An example of a plural is the English word boys, which corresponds to the singular boy.
Standard Romanian shares largely the same grammar and most of the vocabulary and phonological processes with the other three surviving varieties of Eastern Romance, namely Aromanian, Megleno-Romanian, and Istro-Romanian.
In linguistics, agreement or concord occurs when a word changes form depending on the other words to which it relates. It is an instance of inflection, and usually involves making the value of some grammatical category "agree" between varied words or parts of the sentence.
Yiddish grammar is the system of principles which govern the structure of the Yiddish language. This article describes the standard form laid out by YIVO while noting differences in significant dialects such as that of many contemporary Hasidim. As a Germanic language descended from Middle High German, Yiddish grammar is fairly similar to that of German, though it also has numerous linguistic innovations as well as grammatical features influenced by or borrowed from Hebrew, Aramaic, and various Slavic languages.
The morphology of the Welsh language has many characteristics likely to be unfamiliar to speakers of English or continental European languages like French or German, but has much in common with the other modern Insular Celtic languages: Irish, Scottish Gaelic, Manx, Cornish, and Breton. Welsh is a moderately inflected language. Verbs inflect for person, number, tense, and mood, with affirmative, interrogative, and negative conjugations of some verbs. There is no case inflection in Modern Welsh.
The grammar of the Polish language is complex and characterized by a high degree of inflection, and has relatively free word order, although the dominant arrangement is subject–verb–object (SVO). There commonly are no articles, and there is frequent dropping of subject pronouns. Distinctive features include the different treatment of masculine personal nouns in the plural, and the complex grammar of numerals and quantifiers.
Hindustani, the lingua franca of Northern India and Pakistan, has two standardised registers: Hindi and Urdu. Grammatical differences between the two standards are minor but each uses its own script: Hindi uses Devanagari while Urdu uses an extended form of the Perso-Arabic script, typically in the Nastaʿlīq style.
In linguistics, the term nominal refers to a category used to group together nouns and adjectives based on shared properties. The motivation for nominal grouping is that in many languages nouns and adjectives share a number of morphological and syntactic properties. The systems used in such languages to show agreement can be classified broadly as gender systems, noun class systems or case marking, classifier systems, and mixed systems. Typically an affix related to the noun appears attached to the other parts of speech within a sentence to create agreement. Such morphological agreement usually occurs in parts within the noun phrase, such as determiners and adjectives. Languages with overt nominal agreement vary in how and to what extent agreement is required.
A postpositive adjective or postnominal adjective is an adjective that is placed after the noun or pronoun that it modifies, as in noun phrases such as attorney general, queen regnant, or all matters financial. This contrasts with prepositive adjectives, which come before the noun or pronoun, as in noun phrases such as red rose, lucky contestant, or busy bees.
Vietnamese is an analytic language, meaning it conveys grammatical information primarily through combinations of words as opposed to suffixes. The basic word order is subject-verb-object (SVO), but utterances may be restructured so as to be topic-prominent. Vietnamese also has verb serialization. In sentences, the head of the phrase usually precedes its complements, nouns are classified according to series of lexical parameters, and pronouns may be absent from utterances. Question words in the language do not exhibit wh-movement.
In linguistic morphology, inflection is a process of word formation in which a word is modified to express different grammatical categories such as tense, case, voice, aspect, person, number, gender, mood, animacy, and definiteness. The inflection of verbs is called conjugation, while the inflection of nouns, adjectives, adverbs, etc. can be called declension.
The morphology of the Welsh language shows many characteristics perhaps unfamiliar to speakers of English or continental European languages like French or German, but has much in common with the other modern Insular Celtic languages: Irish, Scottish Gaelic, Manx, Cornish, and Breton. Welsh is a moderately inflected language. Verbs conjugate for person, tense and mood with affirmative, interrogative and negative conjugations of some verbs. A majority of prepositions inflect for person and number. There are few case inflections in Literary Welsh, being confined to certain pronouns.
This article deals with the grammar of the Udmurt language.
English nouns form the largest category of words in English, both in the number of different words and how often they are used in typical texts. The three main categories of English nouns are common nouns, proper nouns, and pronouns. A defining feature of English nouns is their ability to inflect for number, as through the plural –s morpheme. English nouns primarily function as the heads of noun phrases, which prototypically function at the clause level as subjects, objects, and predicative complements. These phrases are the only English phrases whose structure includes determinatives and predeterminatives, which add abstract-specifying meaning such as definiteness and proximity. Like nouns in general, English nouns typically denote physical objects, but they also denote actions, characteristics, relations in space, and just about anything at all. Taken all together, these features separate English nouns from other lexical categories such as adjectives and verbs.
