Grammar pronoun

Personal Pronoun - Subject	I	you	he/she/it	we	they
Personal Pronoun - Object	me	you	him/her/it	us	them

 

The personal pronoun is used to refer to someone or something already mentioned (he, she, it etc.), or to refer to the person speaking (I, me etc.) or the person listening (you).

Note!

I, me, he, she, him, her, you = a person

you, we, us = people

it = thing

they, them = things or people

The possessive pronoun shows who the thing being referred to belongs to or is associated with. In English these pronouns change form to show their function.
