Possessive pronouns indicate ownership or belonging. Example: The house is [mine], not [yours].
Reflexive pronouns refer back to the subject of the sentence. Example: She washed [herself] before the party.
Demonstrative pronouns point to specific things. Example: This is my pen, not [that].
Relative pronouns introduce relative clauses and connect them to nouns. Example: The car [that] I bought is red.
Interrogative pronouns are used to ask questions. Example: [Who] is that person over there?
