Person 1: You look like a boss!

Person 2: Becase I'm a boss.

Person 3: Boss of whose?

I want to know if person 3 is using "whose" right or if "whom" is needed to make the sentence grammatical.

Note. I know that I can say "whose boss?" And I be correct. But I would like to know if is even possible to have a question constructed like that and if it will be correct grammatically speaking.

All answers will be appreciated. Thanks...

  • Do you have some examples (or can you search online for some) that use "of whose"?

  • No I don't have and I can't find any online that is why I'm asking if is even possible to make such construction. Apr 15, 2016 at 6:38
  • Whose boss.... suits better!

1 Answer 1


of requires a noun or pronoun in the accusative form, for example

here is a photo of me - me is the accusative of I.

Whose is the genitive form of who, so you can't use it after of. You have to used the accusative form, which is whom.

Boss of whom?

This is the definitely the best way to say it in this context, because it places the emphasis on Boss. You could also say "Whose boss?" but this is less effective because it places emphasis on whose.
