Pronouns
Pronouns refer to and replace nouns (the names of people, places, and things) that have already been mentioned, or that the speaker/writer assumes are understood by the listener/reader. For example, “I want you to read this again.” The words I, you, and this are pronouns. In this sample sentence, it isn’t necessary to actually see the nouns (writer, reader, and sentence) because the writer’s/speaker’s meaning is obvious.
