RELATIVE PRONOUNS
Who/Whom, Which, and That

Relative pronouns connect two ideas in one sentence. They give us more information about a person, animal, or thing.

• Who → refers to people.
  The teacher who lives nearby is very kind.

• Whom → the object form of who. It’s more formal and often replaced by who in everyday English.
  The man whom you met is my uncle.

• Which → refers to animals or things.
  The book which I bought is interesting.

• That → can refer to people, animals, or things. It is often used in everyday speech instead of who or which.
  The car that I drive is very old.

 Tip: In casual English, “that” is more common than “which” or “whom.”
