Here are some simple grammar rules to use pronouns and possessive adjectives / possessive pronouns.
Pronouns replace nouns. You can use them to avoid repetition.
David is a doctor. He is a doctor. (He = David.)
Sarah is a lawyer. She is a lawyer. (She = Sarah.)
Two types of pronouns are subject pronouns, and object pronouns.
Subject pronouns are pronouns that replace the nouns which are the subject of the verb.
Object pronouns are pronouns that replace the nouns which are the object of the verb.
Subject pronouns are the subject of the verb.
John and Alice live in New York. They have a house in Brooklyn.
Alice is a lawyer. She loves her job.
John is a doctor. He works in a hospital.
Object pronouns are the object of a verb. They come after the verb, and after prepositions.
Here's a list of subject and object pronouns:
I ----- me
You ---- you
He ---- him
She --- her
It ---- it
We ---- us
They ---- them
