Who or Whom: Which Is Correct?
Updated · Which One Is Correct editorial team
Quick answer: The confusion between who and whom often trips up even skilled writers, but the rule is straightforward. Use who when the word acts as the subject of a sentence or clause. Use whom when it serves as the object of a verb or preposition. Mastering this distinction elevates your writing clarity and precision.
The Short Answer
Who is the subject, whom is the object. This fundamental rule determines which form you must choose in any given sentence structure.
People confuse them because modern English often drops the object form in casual speech. Many speakers use who in every position, making whom feel overly formal or stiff to contemporary ears.

| Form | Status | Use it when |

| Whom | Interrogative | Asking about the identity of the person affected by something. |

Frequently Asked Questions
Can I use who instead of whom in casual conversation?
Yes, using who in object positions is very common in informal speech and writing. However, whom remains the standard choice for formal documents, academic papers, and professional correspondence.
Why does whom sound so formal and old-fashioned?
Language evolves naturally, and object pronouns often drop in casual contexts. Over time, who has absorbed many roles, making whom feel stiff. Yet, knowing whom preserves precision in serious writing.
Is it wrong to end a sentence with whom?
No, ending a sentence with whom is grammatically correct when it follows a preposition. While some style guides prefer moving the preposition forward, ending with whom is acceptable and clear.
How do I know if whom is part of a compound subject?
Whom cannot be part of a compound subject. If the word shares the action with another noun, you must use who. Test by removing the other name and seeing if he fits.
