What is a Pronoun?

A pronoun can replace a noun or another pronoun. You use pronouns like "he," "which," "none," and "you" to make your sentences less cumbersome and less repetitive.
Grammarians classify pronouns into several types, including the personal pronoun, the demonstrative pronoun, the interrogative pronoun, the indefinite pronoun, the relative pronoun, the reflexive pronoun, and the intensive pronoun.

Example:

Subjective personal pronoun-I,you,she,he,it.we,they

Objective personal pronoun-me,her,him,them

Possessive personal pronoun-mine,yours,her,his

Demonstrative pronoun-this,that,these,those

Interrogative pronoun-who,whom,which,what

Relative pronoun-who,whom,that,which

Indefinite pronoun-all,another,any,anybody

Reflexive pronoun-myself,yourself,himself
