Explain the distinction between who and whom.

The distinction between "who" and "whom" lies in their usage as pronouns in a sentence. "Who" is used as the subject of a sentence or clause, while "whom" is used as the object of a verb or preposition. In simpler terms, "who" is used when referring to the person performing an action, and "whom" is used when referring to the person receiving the action.
