In what circumstances do you use the word "WHOM" and "WHO"?

Question

For eg. May i know WHOM am i speaking to please?
or
May i know WHO am i speaking to please?

Answer 1

As a rule of thumb, if you can put a preposition before "whom", then the "whom" is correct.

?Who do you trust?
*Whom do you trust
*In whom do you trust?

Answer 2

You use "who" when "who" is the Subject of the sentence, the thing that the verb of the sentence is doing the action to. "May I ask to whom am I speaking?" is correct. (by the way never end a sentence with a preposition like I just did in the first sentence). Sorry If I didn't explain th answer in a way that you would understand.

Answer 3

"Who" is the subject, the person doing the action:

May I know WHO is speaking, please?

"Whom" can be any kind of object, not only the object of a preposition:

direct object: Whom did you call?
indirect object (although normally you'd rephrase so it has "to")
You gave WHOM the book? (I can't believe it!)
(more commonly): To whom did you give the book? (neutral question)

object of a preposition: To whom would you like to speak?
For whom are you planning this surprise?

Note that it makes no difference if it's an imbedded question (for example your "may I know", or "He asked me to whom I was speaking"), the "case" remains the same.

An easy way to remember is, use "whom" where you'd use "him" and "who" where you'd use "he".

Answer 4

If it is the subject, you use who. Object, use whom. It is tricky with questions, so try to rephrase it as a statement. For example, 'May I know ___ I am speaking to, please?' Can become 'I am speaking to ___.' This is an object, so the correct word is 'whom'. It follows the same rules as 'I' and 'me'.

Answer 5

This question has come up many times on Yahoo! Answers. I answered it just a couple of days ago, actually. Do a little search or just look back at questions I have answered in the past few days and you'll find the answer.

Answer 6

The difference between who and whom is exactly the same as the difference between I and me, he and him, she and her, etc. Who, like I, he, and she, is a subject - it is the person performing the action of the verb. Whom, like me, him, and her, is an object - it is the person to/about/for whom the action is being done.

Ex:
- With whom am I speaking?

- Who am I speaking to/with?

Answer 7

I cant remember the exact rule, but i think if there's a preposition, u use whom.

may i know *to whom* i am speaking?
*with whom* are you meeting tonight?

who do you know at that table?
who will be there tonight?

Answer 8

To whom mean with the person you are talking to
if you say only who it is grammatically incorrect because you are not saying with who or to who which is the translation of whom

Answer 9

asking questions ,uncertainty,curiousity,fear
