In linguistics and grammar, a pronoun is a word or a group of words that one may substitute for a noun or noun phrase.
Singular they, along with its inflected or derivative forms, them, their, theirs, and themselves, is a gender-neutral third-person pronoun. It typically occurs with an indeterminate antecedent, in sentences such as:
English grammar is the set of structural rules of the English language. This includes the structure of words, phrases, clauses, sentences, and whole texts.
A noun phrase – or NP or nominal (phrase) – is a phrase that usually has a noun or pronoun as its head, and has the same grammatical functions as a noun. Noun phrases are very common cross-linguistically, and they may be the most frequently occurring phrase type.
In Modern English, he is a singular, masculine, third-person pronoun.
In Modern English, we is a plural, first-person pronoun.
In Modern English, it is a singular, neuter, third-person pronoun.
In Modern English, the word "you" is the second-person pronoun. It is grammatically plural, and was historically used only for the dative case, but in most modern dialects is used for all cases and numbers.
A possessive or ktetic form is a word or grammatical construction indicating a relationship of possession in a broad sense. This can include strict ownership, or a number of other types of relation to a greater or lesser degree analogous to it.
In Modern English, they is a third-person pronoun relating to a grammatical subject.
The English personal pronouns are a subset of English pronouns taking various forms according to number, person, case and grammatical gender. Modern English has very little inflection of nouns or adjectives, to the point where some authors describe it as an analytic language, but the Modern English system of personal pronouns has preserved some of the inflectional complexity of Old English and Middle English.
Possessive determiners are determiners which express possession. Some traditional grammars of English refer to them as possessive adjectives, though they do not have the same syntactic distribution as bona fide adjectives.
In linguistics, especially within generative grammar, phi features are the morphological expression of a semantic process in which a word or morpheme varies with the form of another word or phrase in the same sentence. This variation can include person, number, gender, and case, as encoded in pronominal agreement with nouns and pronouns. Several other features are included in the set of phi-features, such as the categorical features ±N (nominal) and ±V (verbal), which can be used to describe lexical categories and case features.
An indefinite pronoun is a pronoun which does not have a specific, familiar referent. Indefinite pronouns are in contrast to definite pronouns.
Personal pronouns are pronouns that are associated primarily with a particular grammatical person – first person, second person, or third person. Personal pronouns may also take different forms depending on number, grammatical or natural gender, case, and formality. The term "personal" is used here purely to signify the grammatical sense; personal pronouns are not limited to people and can also refer to animals and objects.
In Modern English, I is the singular, first-person pronoun.
The English pronouns form a relatively small category of words in Modern English whose primary semantic function is that of a pro-form for a noun phrase. Traditional grammars consider them to be a distinct part of speech, while most modern grammars see them as a subcategory of noun, contrasting with common and proper nouns. Still others see them as a subcategory of determiner. In this article, they are treated as a subtype of the noun category.
English nouns form the largest category of words in English, both in terms of the number of different words and in terms of 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 the language's other lexical categories, such as adjectives and verbs.
English determiners are words – such as the, a, each, some, which, this, and numerals such as six – that are most commonly used with nouns to specify their referents. The determiners form a closed lexical category in English.
English adjectives form a large open category of words in English which, semantically, tend to denote properties such as size, colour, mood, quality, age, etc. with such members as other, big, new, good, different, Cuban, sure, important, and right. Adjectives head adjective phrases, and the most typical members function as modifiers in noun phrases. Most adjectives either inflect for grade or combine with more and most to form comparatives and superlatives. They are characteristically modifiable by very. A large number of the most typical members combine with the suffix -ly to form adverbs. Most adjectives function as complements in verb phrases, and some license complements of their own.
