While questions regarding the usage of Who vs Whom are rare on the SAT, we want to give you a few rules to help you quickly identify the correct answer should you come across them. We won’t go into the grammatical details here since the questions are so rare, but if you follow these rules, these questions will be easy to beat!
Rule #1: Who + Verb
If the Who is directly followed by a Verb, then you would keep Who instead of Whom. For instance, in the sentence “I think I found the man who stole my car”, the “who” is followed directly by the verb “stole”, so we keep it as Who instead of Whom.
Rule #2: Whom + Noun or Pronoun
If the Who is directly followed by a Noun or a Pronoun, you would use Whom instead of Who. Let’s modify the first sentence as an example. If the sentence was “I found the man whom I think stole my car”, then the “who” is followed directly by the Pronoun “I”, so we use “Whom” instead of “who”.
Rule #3: Preposition + Whom
When you have a Preposition followed by the Who, you should use Whom instead of Who. An example of this can be found in the sentence “With Whom did he steal my car?”. Because the “who” is preceded by the Preposition “with”, you would use Whom instead of Who.
Now that you have these rules, you should have no problem crushing these questions if you come across them.
