GRAMMAR: Pronouns

Pronouns take the place of one or more nouns or a group of words in a sentence. Like nouns, they can be used to refer to a person, place, or a thing.
Pronouns are classified as personal, intensive/reflexive, indefinite, possessive, relative, interrogative, and demonstrative.

Personal Pronouns serve as the subject of a sentence, the object of a verb or preposition, to show possession, for emphasis (called intensive), or to refer action back to the subject (called reflexive).

Example of Subject: She is simply too good to be true.
Example of Object: Tell him that the bird died. (object of verb) and Break the news to him gently. (object of a preposition)
Example of Possessive: Your house is a landmark.
Example of Intensive: The quarterback himself changed the call. (the pronoun himself emphasizes the subject quarterback)
Example of Reflexive: Jane taught herself to use the computer. (the pronoun herself refers the action back to the subject)

Indefinitive Pronouns refer to unspecified people or things.
Ex: all, both, each, everyone, most, none, some, few, many, etc.
Possesive Pronouns, unlike possessive nouns, never take an apostrophe.
Ex: my/mine, our/ours, your/yours, his/her/hers/its, their/theirs, etc.
Relative Pronouns can be used to avoid repeating the noun within a sentence.
Ex: who, whom, whose, which, of which, that
Interrogative Pronouns that introduce questions.
Ex: who, whom, whose, what, which
Demonstrative Pronouns generally indicate nearness to or distance from the speaker, either literally or symbolically.
Ex: this, that, these, those
