There are two main types of pronouns in English. They are subject pronouns (I, you, he, she ...) and object pronouns (Me, you, him, her ...).
• I -> Me
• You -> You
• He -> Him
• She -> Her
• It -> It
• We -> Us
• They -> Them
Object pronouns come after a verb or preposition. They are usually found at the end of a sentence.
• Do you know me?
• I can help you!
• He likes her.
• They invited us.
• He can teach them English.
