Most of the personal pronouns have different subject and object forms: The most common pronouns are the personal pronouns, which refer to the person or people speaking or writing ( first person), the person or people being spoken to ( second person), or other people or things ( third person). Pronouns refer to either a noun that has already been mentioned or to a noun that does not need to be named specifically. A pronoun is a word that is used instead of a noun or noun phrase.
