What's the difference between "who" and "whom"?

Answer: B
Differences in who and whom

Differences will be explained based on these 2 examples:
The man is a lawyer. The man is my friend.
The man, who is a lawyer, is my friend.

The man is a lawyer. The reporter interviewed him.
The man, whom the reporter interviewed, is a lawyer.

Difference 1:
From the 2 examples, you should see that there are always 2 actors for "whom" - the man and the reporter, and an action done. (Whom the reporter interviewed) And because "who" just describes the person in question, it has only 1 actor. (Who is a lawyer).

Difference 2
....who IS a lawyer....
...whom THE REPORTER interviewed....

The word(s) that follows after "whom" would always be a person or an animal. Never "is/am/are/was/were" etc.
The word after "who" will always be either a verb or is/am/are/was/were" etc.

This should be very clear now!

Who is the subject and whom is an object, the best example would be " Who is going out with whom?"

In English it's usually "for whom, to whom."

He's the one who i invited.
If you said, "He's the one whom i invited" people would think you were outdated and
wouldn't know if you were right or wrong.

(b) whom

whom is the objective pronoun.

Who is a subject pronoun and whom is an object pronoun.
In the sentence that you wrote, whom is correct choice it is the direct object of the verb invited.


I'm a language teacher.

who and whom is the say thing just written in different text.whom means who for example

''he went to the park with whom he thought was a friend''

''he went to the park with who he thought was a friend'' basically they are the same thing just written differently
