Do you use who or whom? There is a lot of confusion about these two pronouns. The answer is you use who if it refers to the subject of the sentence and whom if it refers to the object in the sentence. Clear as mud, huh? It may be hard to remember those days of diagramming sentences in English class (do they even do that anymore?), but actually this is quite simple.
When you’re using who, the person you’re talking about is the one doing something in the sentence.
Who cleaned up the table?
When you use whom, you are talking about someone as the object in the sentence.
Georgia invited whom?
Georgia is the subject of the sentence, and whom is the object because you want to know who she invited.
If you can restate the sentence using the words him or her, use whom.
Georgia invited him.
Remember the m on the end of both him and whom and you’ll do all right.
