Who? What? Which?

We use WHO for people:

  • Who are you? I'm Tom's sister, Claire.

We use WHAT for people, animals and things:

  • What do you do for a living? I'm a doctor.
  • What are those? They are bears.
  • What is that? It's an oak.

We use WHICH for people, animals and things when we want a specific answer:

  • Which one is your teacher?
  • Which animal sleeps in winter?
  • Which dress do you prefer?


WHOM is the object form of WHO. We use WHOM when the person is the object of the verb:

  • Whom did you see? I saw John. (John is the object of the verb.)
  • Whom did you tell? I told Mary. (Mary is the object is the object of the verb.)


Watch out! When you don't know whether to use WHO or WHOM, try this simple trick:

If you can replace the word with “he”’ or “’she,” use WHO.

  • Who did this? She did.

If you can replace it with “him” or “her,” use WHOM.

  • Whom did you see? I saw him.


We use WHOSE to ask who something belongs to:

  • Whose house is that?
  • I don't know whose this is.
