Staring down the grammar puzzle of For Who or For Whom can shake even a confident writer’s foundation. Missteps like using “for who” in a formal message might go unnoticed by some, but others will catch the slip – and your professionalism takes a hit. The truth is, language carries authority, and a polished sentence can elevate your reputation. Learning how to use the right pronoun in the right context, especially when it follows prepositions like to, for, or with, instantly communicates respect for your reader and mastery of writing mechanics.
Here’s the key difference: “who” plays the subject role – it acts. “Whom” is the object – it receives the action. If you can replace it with “he,” then “who” is correct. If “him” works better, “whom” is your winner. These quick memory hacks work wonders when you’re knee-deep in drafting. A solid mental guide like this ensures smoother communication and helps you maintain clarity in everything you write. And once you trust your instincts, you’ll quit second-guessing your grammar and write confidently, with structure and style that truly shine.
Understanding “Who” vs “Whom” – Grammar Made Simple
“Who” and “whom” both refer to people, but their roles differ.
- Who = subject (the one doing an action)
- Whom = object (the one receiving action)
Think of it like a relay race: one runs, the other gets the baton. Here’s a simple comparison:
| Pronoun | Role | Example |
| Who | Subject | Who called you? |
| Whom | Object | Whom did you call? |
Use who when the pronoun stands in for the subject. Choose whom when it represents the object. That sets the foundation.
Grammar Rules: Subjective vs Objective Pronouns
Subjects act. Objects receive. You’re already comfortable with pronouns like he/him, she/her, or they/them – this is the same concept.
- He/him example: He called her.
- Who/whom version: Who called her? → She called him. → She called whom?
Who replaces the subject (he), whom replaces the object (him). English packs nuances into pronouns – understanding them sharpens your writing.
“For Whom” and the Preposition Rule
Prepositions require objective pronouns. That means after for, to, with, by, about, from, or in, you often need whom.
✔️ For whom are you buying this gift? ❌ For who are you buying this gift?
Formal writing and speech rely on this rule. Yet many avoid it in daily dialogue, claiming “for who” sounds more fluid. Though common, “for whom” is still the correct choice – especially in writing.
Why “For Who” Still Happens – When It’s Accepted
Language evolves. Conversational English often breaks strict rules. Phrases like for who appear in dialogue and social media, and many linguists accept them casually.
Still, appearances matter: in formal emails, academic essays, and job materials, “for whom” is the right pick. Think of it like dress code: casual versus business formal.
Memory Tricks: Know Which One to Use
Try the “he/him” test:
- Restate without the preposition:
- Is it he or him?
- He → who, Him → whom
- Flowchart-like logic:
- After for, to, with, flip to him → whom → e.g., for whom
Mnemonic device: HIM = WHOM, HE = WHO.
Edge Cases & Tricky Constructions
Some sentences can get awkward:
- “To whom do you believe resonating is essential?” (Grammatically correct, but formal)
- Informal rewrite: “Who do you think resonates more?”
When writing formally, choosing structure over awkward phrasing matters. Academic papers often stick with whom, but popular media may not.
The Role of “Whom” in Professional Writing
Using “for whom” properly strengthens your:
- Cover letters and resumes
- Legal documents and proposals
- Academic essays and reports
Case Study: Two job applicants wrote cover letters.
- Candidate A wrote: “This book is for who it may concern.”
- Candidate B wrote: “This letter is for whom it may concern.”
Hiring managers rated B as more polished – precision matters.
Why “Whom” May Be Fading – But Still Needed
Language experts confirm that “whom” usage is declining. Many English speakers now skip it. Still, major style guides like APA, Chicago, and AP retain “whom” in formal contexts.
History shows that pronouns change slowly. Until “whom” disappears from formal writing, you’ll impress readers by using it correctly.
Real Feel Examples: Putting It Into Practice
| Context | Incorrect | Correct |
| Business email | I don’t know for who this file is. | I don’t know for whom this file is. |
| Conversational text | I don’t know who it’s for. | I don’t know who it’s for. (Acceptable informally) |
| Interview question | For who did you complete the report? | For whom did you complete the report? |
Knowing both forms lets you choose based on tone and audience.

FAQs
Is it grammatically correct to say “for who”?
Not in formal writing. “For who” is considered grammatically incorrect because the preposition “for” requires an objective pronoun. The correct version is “for whom”. However, in casual speech, many people say “for who,” and it’s often accepted informally.
How can I quickly tell whether to use “who” or “whom”?
Use the “he/him” trick:
- Replace the clause with “he” or “him.”
- If “him” fits, use whom.
- If “he” fits, use who.
Example:
- You’re writing: This is the person ___ I spoke with.
- Test: I spoke with him. → Whom is correct: This is the person whom I spoke with.
Why does “whom” sound old-fashioned?
Because everyday English is becoming more informal, and many speakers drop strict grammar rules in casual speech. Words like “whom” are falling out of common use, but they still matter in formal, professional, and academic settings.
Is “whom” still used in professional writing?
Yes. Major style guides like APA, MLA, and The Chicago Manual of Style still encourage correct “who” vs. “whom” usage in formal contexts. You’ll see “whom” in legal writing, scholarly articles, business communications, and formal letters.
Can I just avoid using “whom” altogether?
Technically, yes – you can rephrase to avoid it. For example, instead of writing “To whom should I send the document?” you could say “Who should get the document?”
But understanding the difference lets you write with precision and authority when it matters most.
