Differentiation between two types of pronouns:

Pronouns are words used in place of nouns to avoid repetition. There are two types of pronouns, personal pronouns, and possessive pronouns.

Personal pronouns are used to refer to a person or thing. They include words like I, you, he, she, it, we, and they. Personal pronouns can be subjective, objective, or possessive. Subjective pronouns are used as the subject of a sentence, while objective pronouns are used as the object of a sentence. Possessive pronouns show ownership or possession.

Possessive pronouns, on the other hand, show ownership or possession. They include words like mine, yours, his, hers, its, ours, and theirs. Possessive pronouns are used to indicate that something belongs to a particular person or group.

In summary, personal pronouns are used to refer to a person or thing, while possessive pronouns show ownership or possession.
