Pronoun

In linguistics and grammar, a pronoun is a pro-form that substitutes for a noun phrase (including a noun phrase consisting of a single noun) with or without a determiner, such as you and they in English. The replaced phrase is the antecedent of the pronoun. A pronoun used for the item questioned in a question is called an interrogative pronoun, such as who.

For example, consider the sentence "John gave the coat to Alice." All three nouns in the sentence can be replaced by pronouns: "He gave it to her." If the coat, John, and Alice have been previously mentioned, the listener can deduce what the pronouns he, it and her refer to and therefore understand the meaning of the sentence. However, if the sentence, "He gave it to her," is the first presentation of the idea, none of the pronouns have antecedents, also called unprecursed pronouns, and each pronoun is therefore considered ambiguous.

Types of pronouns

Common types of pronouns found in the world's languages are as follows.

A. Personal pronouns (stand in place of the names of people or things):

1. Subjective pronouns (are used when the person or thing is the subject of the sentence or clause). English example: I like to eat chips but she doesn't.

• Second person formal and informal pronouns (T-V distinction). For example, vous and tu in French. There is no distinction in modern English, though Elizabethan English marked the distinction with "thou" (singular informal) and "you" (plural or singular formal).
• Inclusive and exclusive "we" pronouns (indicate whether or not the audience is included). There is no distinction in English.
• Intensive pronouns (re-emphasize a noun or pronoun that has already been mentioned). English uses the same forms as for the reflexive pronouns; for example: I did it myself (contrast reflexive use I did it to myself).

2. Objective pronouns (are used when the person or thing is the object of the sentence or clause). English example: John likes me but not her.

• Direct and indirect object pronouns. English uses the same forms for both; for example: Mary loves him (direct object); Mary sent him a letter (indirect object).
• Reflexive pronouns (are used when a person or thing acts on itself). English example: John cut himself.
• Reciprocal pronouns (refer to a reciprocal relationship). English example: They don't like each other.

3. Prepositional pronouns (come after a preposition). No distinct forms exist in English; for example: Mary looked at him.

4. Disjunctive pronouns (are used in isolation), or in certain other special grammatical contexts. No distinct forms exist in English; for example: Who does this belong to? Me.

5. Dummy pronouns (are used when grammatical rules require a noun/ pronoun, but none is semantically required). English example: It is raining.

B. Possessive pronouns (are used to indicate possession or ownership).

1. In strict sense, the personal pronouns are only those that act syntactically as nouns. English example: Those clothes are mine.
2. Often, though, the term "possessive pronoun" is also applied to the so-called possessive adjectives (or possessive determiners). For example, in English: I lost my wallet. They are not strictly speaking pronouns because they do not substitute for a noun or noun phrase, and as such some grammarians classify these terms in a separate lexical category called determiners (they have a syntactic role close to that of adjectives, always qualifying a noun).

C. Demonstrative pronouns (distinguish the particular objects or people that are referred to from other possible candidates). English example: I'll take these.

D. Indefinite pronouns (refer to general categories of people or things). English example: Anyone can do that.

1. “Distributive pronouns” (are used to refer to members of a group separately, rather than collectively). English example: To each his own.
2. “Negative pronouns” (indicate the non-existence of people or things). English example: Nobody thinks that.

E. Relative pronouns (refer back to people or things previously mentioned). English example: People who smoke should quit now.

Indefinite relative pronouns have some of the properties of both relative pronouns and indefinite pronouns. They have a sense of "referring back", but the person or thing to which they refer has not previously been explicitly named. English example: I know what I like.

F. Interrogative pronouns (ask which person or thing is meant). English example: Who did that?

Pronouns and determiners

Pronouns and determiners are closely related, and some linguists think pronouns are actually determiners without a noun phrase. The following chart shows their relationships.

	Pronoun	Determiner
Personal (1st/2nd)	we	we Americans
Personal (3rd)/ Definite	he	the American
Possessive	ours	our land
Demonstrative	this	this American
Indefinite	some	some Americans
Interrogative	who	which American

Pronouns in English

English has the following personal pronouns:

1. First-person singular (I)
2. First-person plural (we) - inclusive (you and I) and exclusive (someone else and I but not you)
3. Second-person singular or plural (you) - many English speakers amplify the pronoun with following words such as "you all", "you guys", "you both", etc. to disambiguate singular/plural
4. Second-person singular (archaic) (thou) - other forms: thee (object), thine (possessive), thy (actually, a determiner)
5. Second-person plural (archaic) (ye) - used as a subjective pronoun (subject) only: "If ye love me, keep my commandments."
6. Third-person singular masculine (he) - used both for humans and male animals
7. Third-person singular feminine (she) - used for humans and female animals
8. Third-person singular human (they) - used widely in informal educated speech, e.g. "If a customer requires help, they should contact ..." (stylistically in formal writing, "they" would be replaced with he or she here)
9. Third-person singular generic human (one) - in formal usage, e.g. "If one is kind to others, they often reciprocate." - informally, English speakers would use you here
10. Third-person singular neuter (it) - used for objects and animals whose sex is unknown and as a dummy subject, e.g. "It is raining."
11. Third-person plural (they)

Unlike English nouns, which are undeclined for case except for possession (woman/woman's), English pronouns have a number of forms or "cases" depending on their grammatical role in a sentence:

1. A subjective case form (I/we/etc.), used when a pronoun is the subject of a finite verb
2. An objective case form (me/us/etc.), used when it is the object of verb or of a preposition
3. A possessive case form (mine/ours/etc.), used when it is the possessor of another noun — one that's used as a determiner, and one that's used as a pronoun or a predicate adjective
4. A reflexive form (myself/ourselves/etc.), which replaces the objective-case form in referring to the same entity as the subject.
