But before you click the back button, please forbear and be patient. This exploration of who versus whom will be painless. Trust me. There will be no discussion of direct and indirect objects. No figuring out the subject or the object in the sentence. And no one is diagramming anything.
In fact, there’s an easy way to tell when you should use who or whom in a sentence. If we had only been taught this in school.
Consider the following sentence:
Who do you consider the best composer?
Should it be who or whom?
Figure it out by turning the sentence around and replacing the who or whom with he or him. If he is wrong, so is who. If him is wrong, so is whom.
Since him is correct, use whom.
