If you’re like most English speakers, you know that there’s a difference between who and whom but you aren’t sure what that difference is. We’re here to help.
Who should be used to refer to the subject of a sentence.
Whom should be used to refer to the object of a sentence.
When in doubt, try this simple trick: If you can replace the word with ‘he’ or ‘she,’ use
who. If you can replace it with ‘him’ or ‘her,’ use
whom.

Who ate my sandwich? (Did he eat my sandwich? Did she eat my sandwich?)
Whom should I talk to about labeling food in the refrigerator? (Should I talk to him? Should I talk to her?)
