This document defines and describes different types of pronouns. It explains that a pronoun takes the place of a noun and can do anything a noun can do in a sentence. The types of pronouns discussed are possessive, personal, reflexive, and interrogative pronouns. Personal pronouns refer to specific persons, places or things and change form based on person, number or gender. Reflexive pronouns end in "-self" or "-selves" and are used when the subject and object are the same.
