I presume you mean who and whom. Who is a subject; whom is an object. HERE'S one place to start studying.
I am reallly confuse about the use of (of whom and whom).
Could you please help me?
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
Thanks a lot!
I think I got it.
