what is the difference between who and whom
Who is used for the subject of a sentence (the doer of the action), while whom is used for the object (the receiver of the action or after a preposition).
What Is the Difference Between Who and Whom?
The core rule (in plain English)
- Use who when the word is doing the action.
- Examples:
- “Who called me?” (who = subject of “called”)
- Examples:
* “She’s the singer who won the contest.” (who = subject of “won”)
- Use whom when the word receives the action or follows a preposition.
- Examples:
- “Whom did you call?” (whom = object of “called” → you called him/her/them)
- Examples:
* “To whom did you send the email?” (whom after preposition “to”)
Grammatically, who matches subject pronouns like I, he, she, we, they; whom matches object pronouns like me, him, her, us, them.
Simple test: he/she vs. him/her
A classic hack:
- If you can replace the word with he or she , use who.
- If you can replace it with him or her , use whom.
Examples:
- “(Who/Whom) is coming to dinner?”
- Try: “He is coming to dinner.” → who is correct.
- “You invited (who/whom)?”
- Try: “You invited him.” → whom is correct.
- “The person (who/whom) I trust most is my sister.”
- Try: “I trust her.” → whom is technically correct: “The person whom I trust most…”
Quick mini-sections and examples
1. When to use “who”
Use who as the subject of a clause:
- “Who left the door open?” (who did the leaving)
- “That’s the player who scored the winning goal.” (who = subject of “scored”)
- “She knows who called earlier.” (who = subject of “called” inside that clause)
2. When to use “whom”
Use whom as:
- The object of a verb:
- “Whom did they choose?” (they chose him/her)
* “The colleague whom I mentioned is here.” (I mentioned him/her)
- The object of a preposition:
- “For whom are you waiting?”
* “My professor, with whom I worked, wrote a recommendation.”
Many style guides point out that whom is especially expected after a preposition at the beginning of a clause (e.g., “To whom it may concern”).
Real-life usage today
In modern, everyday English (especially speech and informal writing), people often use who even where strict grammar would prefer whom. For example:
- “Who did you talk to?” instead of “To whom did you talk?”
Many guides note that whom can sound formal or old-fashioned outside professional or academic contexts. So:
- In casual conversation, “who” is usually fine almost everywhere.
- In formal writing, exams, or job applications, using “whom” correctly can show careful grammar.
Mini FAQ-style list
- Is “whom” disappearing?
- It’s less common in speech but still used in formal writing and fixed phrases (“To whom it may concern”).
- Is it wrong to say “Who are you talking to?”
- It’s very natural and widely accepted in informal English, though traditional grammar prefers “To whom are you talking?”.
- Do I always need to be perfect with whom?
- Not in everyday talk, but it’s helpful to know the rule so you can use it when the context is formal.
Tiny story to lock it in
Imagine a detective story:
“Who stole the jewels?” the inspector asked.
“We don’t know whom they targeted first,” the assistant replied.
Here, who is the thief (the doer), and whom is the victim (the receiver of the action) — that’s the difference in a nutshell.
