On a recent sojourn to the other side of my lovely country (Vancouver, I miss you!), I found myself discussing the grammatical conundrum of who vs. whom. It’s a tricky one, so I thought I’d try to shed some light on when you should be using who and when it should be whom instead.
First of all, both who and whom are interrogative pronouns (along with whose, what and which). We use interrogative pronouns when we want to ask a question. So here’s the nitty-gritty of how who and whom are used:
Who is the nominative form and can be used in the following 2 ways:
1) As the subject of a verb.
Who created the Cylons?
2) As a predicate nominative, following a be-verb.
No way! Boomer was who?
Whom is the objective form and can also be used in 2 different ways, as follows:
1) As the object of a verb.
Whom did Starbuck crush? (whom is the object of crush)
2) As the object of a preposition.
Gaius Baltar, with whom are you in love? (whom is the object of with)
So the simple rule to remember is that who is either the subject or is pointing to the subject, while whom is the object of either a verb or a preposition.
