Possessive pronouns are a type of pronoun that indicate ownership or possession. They are used to replace nouns and show that something belongs to someone or something. Possessive pronouns also help avoid repetition in sentences.

Here are the possessive pronouns in English:

1. Mine - It indicates that something belongs to the speaker. For example: "The book is mine."

2. Yours - It indicates that something belongs to the person being spoken to. For example: "Is this pen yours?"

3. His - It indicates that something belongs to a male. For example: "That is his car."

4. Hers - It indicates that something belongs to a female. For example: "The phone is hers."

5. Its - It indicates that something belongs to a non-human object or an animal. For example: "The dog wagged its tail."

6. Ours - It indicates that something belongs to a group that includes the speaker. For example: "The house is ours."

7. Yours - It indicates that something belongs to a group of people being spoken to. For example: "Is this project yours?"

8. Theirs - It indicates that something belongs to a group of people or objects. For example: "The keys are theirs."

It's important to note that possessive pronouns do not require an apostrophe ('), unlike possessive nouns. For example, "hers" is the possessive pronoun, while "Mary's" is the possessive noun.
