Q&A for How to Use Who and Whom

Yes.

In this case, whom is correct, because the object of your love is your sister Think about it this way -- if a person is having the verb done to (with, about, for, etc.) them, you want to use whom.

Yes, because in this sentence you are the subject, and the invited party will be the object of your action (being invited).

The girl is the object acted upon (talked to) in this sentence. You spoke to her rather than you talked to she. Therefore, whom is correct. However, if she talked to you it would be the other way around, because then "she" talked to you. She would now be the subject. So the girl who spoke to you in the office is my friend.

Although it seems like it should be "whom" (as the object of the preposition "to"), it's actually "who" (as a predicate nominative in the independent clause "who the...teacher would be." "Teacher" is the subject of the clause, "would be" is the verb, and "who" is the predicate nominative).

Yes.

Yes, that's correct. You would not use "whom" in that instance.

"Whom" is correct. "We have given much to him...", "Whom have given much to...", "..to whom we have given much" are all correct phrases.

It should be 'I can well afford to disregard ONE/HE who is capable of ...." It is "who" because it refers to an "action doer" or subject in grammatical terms. You can't use him for the same reason, that we need a subject. So you can say "he is capable of ...." but we can't say "him is capable of...."

You're right. Only "not all who are" is correct. Unfortunately, someone submitted the wrong answer and it got approved.

When you make or receive a phone call and don't know who the person you're speaking to is. Honestly, though, this is a very formal expression that is not used much. If you want to use it, save it for relatively formal phone calls (e.g., business matters). Generally, "May I ask who's speaking?" or even just "Who's speaking?" works best.

Because it modifies a noun ("people"), it's an adjective clause.

Who.

Correct.

The sentence is correct as it is.

"Who," the subject of the sentence.

Yes, or "for whom should I look?"

No. "Who" is correct there.

It is correct as far as the use of "who" and "whom," but it would be more correct (and powerful) to use the active verb "stole," rather than the passive "was stolen." A person speaking English would more likely say or write, "Who stole my watch?"

The wording is correct, there just should be a comma after 'John'. "He went to see John, who he said was his oldest friend."

"Whom" is correct.

"Whom are you working with on the project?" is the correct usage, and can be seen more readily if one rearranges the sentence structure to better match up the syntax: "With whom are you working on the project?" In this case, it becomes more obvious that the "who/whom" question is answered as the object of the preposition "with": "with whom".

Whom.

"Whom" because it's the object of "thought." If "I thought" were not used here, it would be "the man who was one of..."

Whom.

Correct.

This is a tricky one. It's "whom," because it's the object of the verb "sets (free)." It's easier to visualize if you insert the word "he" at the beginning of the sentence: "He whom the son sets free is free indeed." (No comma needed.)

Neither.

Whom. You could say "with whom she may coordinate" to avoid ending a sentence with a preposition.

Yes.
