Here's a breakdown:
* Replaces a noun: Instead of saying "The cat sat on the mat," you can use a pronoun: "It sat on the mat."
* Types of pronouns:
* Personal pronouns: I, me, you, he, him, she, her, it, we, us, they, them.
* Possessive pronouns: mine, yours, his, hers, its, ours, theirs.
* Reflexive pronouns: myself, yourself, himself, herself, itself, ourselves, yourselves, themselves.
* Demonstrative pronouns: this, that, these, those.
* Indefinite pronouns: all, any, each, every, few, many, most, some, none, nobody, nothing, something, anything, everything.
* Relative pronouns: who, whom, whose, which, that.
* Interrogative pronouns: who, whom, whose, which, what.
Examples:
* "John went to the store, and he bought some milk." (He replaces John)
* "That is my favorite book." (That replaces a specific book)
* "Everyone should be treated fairly." (Everyone replaces a group of people)
* "The dog, which was brown, barked loudly." (Which replaces the dog)
Key points to remember:
* Pronouns must agree with the noun they replace in number (singular/plural) and gender (masculine/feminine/neuter).
* Pronouns can be used as subjects or objects in a sentence.
