Here's the quick test, the one place whom is required, and where nobody minds who. *Error of the Day for November 2, 2026 · Language · by erroneo.us Editors* - **Wrong:** The candidate whom we believe will win is speaking tonight. - **Right:** The candidate who we believe will win is speaking tonight. (Who is the subject of will win.) - **Memory trick:** He = who, him = whom (both end in m), and the clause decides, not the verb nearby. ## What people get wrong There are two opposite mistakes here, and the second is more common in careful writing. The first is using *who* where formal grammar wants *whom*: "To who should I send this?" The second is **hypercorrection**, putting in *whom* because it sounds educated, even where the grammar calls for *who*: "Whom shall I say is calling?" or "the man whom I think stole my bike." Speakers usually get the first one wrong. Writers trying hard usually get the second one wrong. ## The rule The American Heritage Dictionary states the traditional rule simply: [*who* is a subject pronoun and *whom* is an object pronoun](https://www.ahdictionary.com/word/search.html?q=who). *Who* does the action; *whom* has the action done to it, or follows a preposition. - *Who* called? (*He* called.) - *Whom* did you call? (You called *him*.) - The editor *for whom* I work. (I work for *her*.) ## The test Rephrase the clause and substitute *he* or *him*. If *he* fits, use *who*. If *him* fits, use *whom*. The *m*'s match. The trick is to test **only the clause the pronoun belongs to**. "The man [who/whom] I think stole my bike": take out "I think" and you get "*he* stole my bike," so it's *who*. The "I think" in the middle makes it look like an object. It isn't. The same goes for verbs and prepositions that come before a whole clause. AHD gives the example ["I know nothing about who supports the governor"](https://www.ahdictionary.com/word/search.html?q=who): *who* is correct and *whom* is an error, because the object of *about* is the entire clause, and inside that clause *who* is the subject of *supports*. AHD's point is that *whom* is used when it is the object, "not when it merely comes after the verb or preposition." ## The fix Wrong: Give the ticket to ~~whomever~~ asks first. Right: Give the ticket to whoever asks first. Why: The object of "to" is the whole clause; inside it, the pronoun is the subject of "asks" (he asks). Wrong: The friend ~~who~~ I was talking to is a pilot. Right: The friend whom I was talking to is a pilot. (Or more naturally: the friend I was talking to.) Why: In formal writing, the object of "to" is whom. In everyday writing, dropping the pronoun avoids the choice altogether. ## When you can relax *Whom* is on the way out of everyday English, and the reference books say so. Cambridge notes that we use whom ["in formal styles or in writing"](https://dictionary.cambridge.org/grammar/british-grammar/who-whom) and "don't use it very often." Oxford's learner's dictionary says [who is usually used as the object pronoun in spoken English](https://www.oxfordlearnersdictionaries.com/definition/english/whom), especially in questions: "Who did you invite to the party?" AHD agrees that in informal contexts "who often replaces whom." It also offers a handy escape: swap in *that*, or drop the pronoun. "The governor whom the actor supports" becomes "the governor the actor supports." There's one place to hold firm. *Whom* [survives as the standard form](https://www.ahdictionary.com/word/search.html?q=who) directly after a preposition: "for whom," "to whom," "with whom," never "for who." If the preposition sounds stiff, move it to the end and use *who*: "Who should I send it to?" ## Try it Pick *who* or *whom*, then check with he/him: 1. ___ do you think will win? (*He* will win: **who**.) 2. To ___ it may concern. (Right after *to*: **whom**.) 3. She hired someone ___ she trusts. (She trusts *him*: **whom** formally; *who*, *that* or nothing in casual writing.) The rule of thumb: if you aren't sure, *who* is the safer error. A misplaced *who* reads as relaxed. A misplaced *whom* reads as someone trying too hard. ## Sources 1. [American Heritage Dictionary: usage note at 'who'](https://www.ahdictionary.com/word/search.html?q=who) 2.
