when do we use whom and who?

Question

I want to know when it would be appropriate to use who and whom.

Answer 1

Here's the easy way to tell. Instead of "who" and "whom" try substituting "he" and "him" into the same sentence. If "he" works better, than you want "who" if "him" works better, then you want "whom".

For example, let's say you're trying to figure out whether it's "To who am I speaking" or "To whom am I speaking". Would you say (this is a little Yoda-like but that's okay) "To he am I speaking" or "To him am I speaking"? The second sounds more correct, so it would be "To whom am I speaking?"

Answer 2

It's to do with the subject and the object of a verb. "who" is
the subject, and "whom" is the object. For example, in
the sentence "Who is giving the present?", the word "who" is the
subject, i.e. the person who is doing the giving. On the other
hand "To whom are you giving the present?", "whom" is the
object, i.e. the person that the giving is being done to.
