Relative pronouns are the pronouns at the beginning of some dependent clauses: who, whom, that, and which.
- Who and whom are used instead of people.
- That and which are used instead of things, places, and ideas.
- That is sometimes also used instead of people.
We also have a special possessive for relative clauses: whose
I don't know whose book that is.
Here are a few examples
- The man who is at the table is waiting to order.
- I don't know that woman to whom you are waving.
- The dog is eating that pizza which was left on the counter.

Who vs. Whom
Whom is more formal and is used after a preposition. "to whom it may concern"
If you are not sure if you should use who or whom check to see if it is following a preposition. If it is not then go ahead and use who.
