Who vs Whom: What’s the Difference? (Easy Rules, Examples & Tricks)
Quick Answer: Who is a subject pronoun (does the action) — like “he” or “she.” Whom is an object pronoun (receives the action) — like “him” or “her.” Memory trick: If you can replace it with “he/she” → use who. If you can replace it with “him/her” → use whom. Example: “Who called?” (He called.) / “Whom did you call?” (You called him.)
Even advanced speakers often mix up “who” and “whom” because the difference is small but important — one acts as the subject, the other as the object. Knowing when to use each doesn’t just improve your grammar; it makes your writing sharper and more professional. This quick guide will clear up the confusion so you can use “who” and “whom” with complete confidence.
What’s the Difference?
| Word | Role | Example |
|---|---|---|
| Who | Subject (does the action) | “Who is calling you?” (He is calling) |
| Whom | Object (receives the action) | “To whom should I address this?” (Address it to him) |
When to Use “Who”
Examples:
• “Who made this cake?”
• “Who is coming over?”
• “Do you know who called?”
When to Use “Whom”
Examples:
• “Whom did you invite?”
• “To whom should I send this?”
• “With whom are you speaking?”
Quick Trick to Remember
If you can replace it with “he/she/they” → use WHO
Example: “___ made this?” → He made this → Who
If you can replace it with “him/her/them” → use WHOM
Example: “Give it to ___” → Give it to him → Whom (“To whom should I give it?”)
Using “Whom” in Relative Clauses
Use “whom” when it connects a clause and acts as the object.
- “The person whom you met yesterday is my colleague.” (You met him)
- “That’s the author whom the critics praised.” (Critics praised him)
“With Who” vs “With Whom”
📌 Formal Writing
“With whom are you going?” (Correct — preposition + object)
💬 Casual Speech
“Who are you going with?” (Widely accepted)
Tip: In formal writing, always use “whom” after prepositions like with, to, for. In casual speech, “who” is often used instead, and that’s widely accepted.
Examples of Who and Whom
📌 Who Examples
“Who wants to join us for lunch?”
“Do you know who finished the report?”
“Can you tell me who is responsible?”
📌 Whom Examples
“Whom did they hire?”
“She’s the person to whom we gave the award.”
“The teacher, with whom I spoke, agreed.”
📌 Both in One Sentence
“Who do you think will hire whom?”
“Do you know who won and whom they beat?”
Handling Complex Sentences
Find the verb and ask: Who does what to whom?
Example: “The manager, who said the project would finish early, congratulated the team whom she selected.”
• “who” = subject (does the action of saying)
• “whom” = object (receives the action of selecting)
Use the he/him test to be sure.
Mini Quiz: Who or Whom?
| Question | Answer |
|---|---|
| ___ left their bag on the table? | Who |
| To ___ did you send the invitation? | Whom |
| I wonder ___ will be chosen. | Who |
| ___ are you going to call? | Whom |
| The woman ___ you met is my aunt. | Whom |
Who = Subject (does the action) → “Who is knocking?” (He is knocking)
Whom = Object (receives the action) → “To whom did you speak?” (Spoke to him)
Final Tip: Use the “he/him” trick to double-check. In formal writing, go with whom when it’s the object. In speech, who is often fine — but knowing the difference strengthens your grammar.
