Personal pronouns take the place of specific nouns that name people, places and things. Personal pronouns are used instead of a name to avoid repetition and to help ease the flow of sentences. Though the name suggests they are only pronouns that describe people, personal pronouns can stand in places, things, or ideas as well.
There are two cases of personal pronouns: subject pronouns and object pronouns.
Personal pronouns can be divided into singular andplural categories depending on the number of items they refer to. Remember, singular means one of something and plural means more than one of something
