The Answer
Who and whom are both standard English forms, but they do different jobs. Who usually names the person doing the action. Whom usually names the person receiving the action, especially in formal writing. In everyday speech, many people use who where older school grammar would prefer whom. Source-1✅

Which Form Is Correct?
Both can be correct. The choice depends on the pronoun’s job inside the sentence. A simple way to see it is to swap in he or him. If he fits, use who. If him fits, use whom. Source-2✅
- Who: Who called earlier? → He called earlier.
- Whom: Whom did you invite? → You invited him.
- Who often appears in everyday speech even where whom is possible.
A Fast Reality Check
If the hidden answer sounds like he, who is the natural fit. If the hidden answer sounds like him, whom is the formal fit.
How The Rule Works
The rule is really about subject and object case. Who belongs to the subject side. Whom belongs to the object side. Formal grammar also keeps whom after a preposition. Source-3✅
| Role In The Sentence | Better Choice | Example | What The Pronoun Is Doing |
|---|---|---|---|
| Subject | Who | Who wrote the note? | The pronoun performs the action. |
| Direct Object | Whom in formal style | Whom did the editor call? | The pronoun receives the action of the verb. |
| Object Of A Preposition | Whom in formal style | To whom was the message sent? | The pronoun follows a preposition. |
| Relative Clause Subject | Who | The writer who called is here. | The pronoun is the subject inside the clause. |
| Relative Clause Object | Whom in formal style | The writer whom I called is here. | The pronoun is the object inside the clause. |
One detail matters a lot: the pronoun’s role inside its own clause controls the choice, not the word standing right before it. That is why who stays correct in the person who called, even though another noun appears first.
Where Whom Still Fits
Whom still sounds natural in a few places: formal questions, formal relative clauses, and phrases with a fronted preposition such as to whom or for whom. It also stays familiar in fixed wording like To whom it may concern. Source-4✅
- Formal question: Whom did the board select?
- After a preposition: To whom should the form be addressed?
- Fixed wording: To whom it may concern
Everyday English vs Formal English
Formal: Whom did you speak to?
Common everyday use: Who did you speak to?
Both will be understood. The second one is much more common in ordinary conversation.
Why The Confusion Happens
This pair gets messy because modern English often leans toward who even when whom is technically available. On top of that, question order and relative clauses can hide whether the pronoun is acting as a subject or an object. That is why Who did you call? sounds easy, while Whom did you call? can feel a bit stiff outside formal writing. Source-5✅
- Speech is faster and looser, so who spreads into object position.
- Question order flips things around, which makes the real role harder to see at first glance.
- Relative clauses hide the pronoun inside a smaller clause, so mistakes become more common.
Examples In Real Sentences
Relative clauses are one of the places where this choice becomes less obvious. Formal English keeps whom in object position, but ordinary English often uses who there, and sometimes drops the relative pronoun completely. Source-6✅

The Spot Where Errors Show Up Most
If the pronoun itself performs the action, use who. If another word performs the action on the pronoun, formal grammar points to whom.
Common Mix-Ups Table
| Sentence | Better Choice | Why |
|---|---|---|
| Whom is calling? | Who is calling? | The pronoun is the subject of is calling. |
| Who did you invite? | Who did you invite? / Whom did you invite? | Whom is the formal object form, but who is common in everyday English. |
| The writer whom won the award | The writer who won the award | The pronoun is the subject inside the clause. |
| To who should I send this? | To whom should I send this? | Formal grammar prefers whom after a fronted preposition. |
| The person whom I work with | The person whom I work with / The person who I work with | Formal grammar allows whom; everyday English often uses who. |
FAQ
Is whom still used in modern English?
Yes. It still appears in formal writing, after some prepositions, and in set wording such as To whom it may concern. It is much less common in everyday speech.
Is Who Did You Invite? wrong?
No. In everyday English, that sentence sounds natural and is widely accepted. In stricter formal grammar, Whom did you invite? matches the object role more closely.
Which sounds more formal: Who Are You Speaking To? or To Whom Are You Speaking??
To whom are you speaking? sounds more formal. Who are you speaking to? is the version most people use in normal conversation.
Do relative clauses always need whom in object position?
No. Formal writing may use whom, but everyday English often uses who or drops the relative pronoun: the person I called.
Why does who show up so often where grammar books mention whom?
Because ordinary English prefers the simpler form. Many speakers keep whom only in polished writing or in a few familiar phrases.
