relative pronouns

[Harue Izo]

Hello,

I am reallly confuse about the use of (of whom and whom).

Could you please help me?

I presume you mean who and whom. Who is a subject; whom is an object. HERE'S one place to start studying.

Thank you for replying mister,

but I did mean ¨of whom¨. A colleague of mine came today and in her exercise book there was this quizz, and between the choices there was¨of whom¨ and also ¨whom¨. when to use one or another?

waiting for your reply

[Harue Izo]

Thanks a lot!

I think I got it.
