Which One of You IS or ARE? Which is correct?

Grammar / By

We usually use “is” with “which one”. We use “is” because of the word “one” which requires a singular verb conjugation. 

Examples

Which one of you is going to the party?

Which one of you is Mike?

Which one is you or are you?

Both “which one is you” and “which one are you” are correct.

We use “which one is you” when “which” is the subject and “which one are you” when “you” is the subject”.
