When it comes to the rule of “WHO v WHOM”, many websites place emphasis on knowing the difference between subjects and objects, or go on and on about clauses and prepositions. But here’s a simple trick that doesn’t include any of that stuff:
Rephrase your sentence using HIM. If it still makes sense, use WHOM.
Example 1: Whom made the mistake?
Rephrase: HIM made the mistake. This sentence, as you can easily see, is incorrect.
Example 2: To whom did you give the letter?
Rephrase: Did you give the letter to HIM? This sentence is correct.
That’s it. That’s all there is to it.
How to remember that? Use this simple mnemonic: Both “him” and “whom” end in “M”.
