what is a personal pronoun 

Dear student,

Here is the answer: 

Personal pronouns  take the place of a proper noun.  These are associated primarily with a particular grammatical person – first person (such as I), second person ( such as you), or third person (such as he, she, it). Personal pronouns may also take different forms depending on number (usually singular or plural) gender, case and formality.  I, Me, You, They, He, She, We, etc are examples of personal pronouns
