Which of the following sentences is correct, and why?

  1. Which of those is your cousin?

  2. Whom of those is your cousin?

More generally, do we say "Which of those people?" or "Whom of those people?"

  • Which of those people?? Whom of those people??

  • which . Whom won't work because it's not the object of a preposition.

  • In your sentences, "which" and "whom" are not relative pronouns, but interrogative pronouns.

  • "Which" or "Who" will work here, but whom won't as it's told you before. See here how to use "whom" in questions: en.oxforddictionaries.com/usage/who-or-whom May 6, 2018 at 3:23

1 Answer 1


I would say, who of those is your cousin (not "whom"; whom is for the object of the sentence, and "cousin" is the subject, not the object).

Which of those is also correct.

In the future, you might want to post these questions on English Language Learners.

  • I'd say 'Which of those ...' is by far the more idiomatic when a smallish set of candidates is involved (and that is almost certainly the case here) and there is a single-member answer. 'Who of those can we possibly trust?', with an unknown size of answer, sounds better to my ears. May 6, 2018 at 5:28
