The question of whether to use “who” or “whom” in a sentence is easier to answer than you might think. These are the basic rules:
- “Who” refers to the subject of a sentence. “Whom” refers to the object.
- “Who” and “whom” work in the same way as “he” and “him.” You can work out which one to use by asking yourself the following:
- “Who did that? He did” – “who” is correct. “Whom should I call? Call him” – “whom” is correct.
- “That” is often used incorrectly in place of “who” or “whom.” Never use “that” in reference to a person.
- Who should I ask for help?
- Whom helped you?
- He was the only person that wanted to help.
- Whom should I ask for help?
- Who helped you?
- He was the only person who wanted to help.
