Who I should pick or whom I should pick?

Question

In a sentence beginning "do you know."

Answer 1

Whom

Here's a general rule to figure out whether 'who' or 'whom' is correct in a sentence. Just re-do the sentence to use 'he' or 'him'.
- If 'he' fits, the word you want in your original sentence is 'who'.
- If 'him' fits, the word you want is 'whom'.

You'd say "I should pick HIM," (not "I should pick HE.")
Therefore the word you want is WHOM, not WHO.

Answer 2

Whom

Who is the subjective case while Whom is objective case.

In your example, I is the subject: I should pick whom (the objective).

Use whom after prepositions (such as to whom, for whom, with whom, etc. because it serves as the object of the preposition)

Use who when it serves as the subject: Who will pick? is similar to I will pick.

Answer 3

who. It is a subject of the second clause, but still a subject (unless of course you want to give it some fancy meaning, like a rhetorical, in which case whom may be appropriate).

Do you know who I should pick? dude.

Answer 4

whom

Answer 5
