Who vs. Whom
Understand the subject-object distinction. Read a concrete example, examine the trade-offs, and try a small exercise to see whether the principle applies to your situation.
Understand the language rule
- Start here. Use who where he or she would fit.
- Add context. Use whom where him or her would fit.
- Keep in mind. Conversational English frequently prefers who; formal contexts may retain whom.
See it in context
“Who called you?” uses a subject. “Whom did you call?” uses an object. A quick substitution can help: if “he” fits, “who” is likely; if “him” fits, “whom” is often the formal choice.
Clarity and register matter: correct grammar should serve the audience, not become a reason for awkward writing.
Mistakes and exceptions
Many conversational speakers use “who” even where traditional grammar prefers “whom.” Forcing “whom” into informal prose can sound stilted.
Practice with your own text
Test “Who/whom did you invite?” by rewriting the answer as “I invited him.” Then decide whether your audience expects formal edited English.
