Getting Who and Whom Choices CorrectFor some reason, we often can't "hear" whether who or whom should be used in most situations. We can hear he and him and I and me and they and them quite easily, but who and whom are difficult. To solve the problem, rearrange a who/whom sentence and replace the who or whom with one of those words we can hear-he/him, they/them, I/me. If we choose a word with an -m in it (him, them, me), we know that whom is correct. If we choose a word without an -m (he, they, I), we know that who is correct. Here are the steps to this trick that we call the "M&M Rule" (because the -m in the words we can hear tells us whether who or whom is correct)
1. Delete the part of the sentence that comes before the who or whom:
2. Replace the who/whom or the whoever/whomever with he or him, with they or them, or with I or me:
3. Read the part of the sentence that you haven't deleted (sometimes you'll have to rearrange it a bit before it makes sense as a sentence) and see whether an -m word or a non-m word sounds right. If an -m word sounds right, use whom in your original sentence. If a non-m word sounds right, use who in your original sentence.
For example, because:
Sounds good to us, we know our original sentence should say:
