If you’ve ever paused mid-sentence wondering “should I say who else or whom else?”, you’re not alone. This is one of the most common grammar mix-ups in English, and even confident writers second-guess themselves here.
The short answer: “who else” is correct almost all the time, especially in modern spoken and written English. “Whom else” is grammatically correct only in specific formal situations, and it’s becoming rarer every year.
In this guide, you’ll learn exactly when to use each one, why the confusion exists, how native speakers actually talk, and how to sound both correct and natural. Think of this as a lesson from your English teacher — clear, practical, and example-heavy.
Quick Answer: Who Else or Whom Else?
- Use “who else” when the word is the subject of the sentence (doing the action).
- Use “whom else” when the word is the object of the sentence or a preposition (receiving the action).
Example:
- Who else is coming to the party? (subject — who else is coming)
- Whom else did you invite? (object — you invited whom else)
If that still feels confusing, don’t worry. By the end of this article, you’ll be able to choose the right one instantly, without even thinking about grammar rules.
What Do “Who Else” and “Whom Else” Mean?
Meaning: Both phrases ask about an additional person, beyond someone already mentioned or implied. The word “else” means “in addition” or “other than this.”
Definition:
- Who else — a subject pronoun combined with “else,” used to ask which other person acts.
- Whom else — an object pronoun combined with “else,” used to ask which other person receives an action or follows a preposition.
Word origin: “Who” comes from Old English hwā, and “whom” comes from hwām, the dative (object) case of the same root word. English used to have more case endings than it does today, which is exactly why “whom” still exists — it’s a grammatical fossil from an older stage of the language.
Quick Tip: If you can replace the word with “he,” use who. If you can replace it with “him,” use whom. (More on this test below.)
Who vs. Whom: The Core Grammar Rule
Before you can master “who else” vs. “whom else,” you need to understand the basic difference between who and whom.
- Who is a subject pronoun. It acts as a sentence.
- Whom is an object pronoun. It receives the action, or it follows a preposition (to, for, with, from, by).
Subject Pronouns vs. Object Pronouns
| Type | Pronouns | Function |
| Subject pronouns | I, he, she, we, they, who | Perform the action |
| Object pronouns | me, him, her, us, them, whom | Receive the action |
Example sentences:
- Who called you? (Who is the subject — who called.)
- Whom did you call? (Whom is the object — you called whom.)
The He/Him Grammar Test
This is the single easiest trick any English teacher will give you.
Step 1: Turn the question into a statement. Step 2: Replace the unknown person with “he” or “him.” Step 3: If “he” fits, use who. If “him” fits, use whom.
Example:
- Question: ___ is going to the meeting?
- Statement: He is going to the meeting. → Use who.
- Question: You are meeting ___?
- Statement: You are meeting him. → Use whom.
Tip to remember: “Him” and “whom” both end in -m. That’s your memory hook.
How Pronouns Work in English Sentences
Every sentence has a subject (the doer) and often an object (the receiver). Pronouns change form depending on their role:
- She (subject) called him (object).
- They (subject) invited her (object).
- Who (subject) called whom (object)?
This subject-object pattern is the backbone of the who/whom rule, and it applies the same way once you add “else.”
Does Adding “Else” Change the Grammar Rule?
No. This is the most important thing to understand: “else” is just an adverb meaning “in addition” or “other than what’s already mentioned.” It doesn’t change the grammatical role of “who” or “whom” at all.
Grammar explanation: “Else” attaches to question words (who, what, where, when, why, how) to broaden the question. It never affects whether the pronoun is a subject or an object.
Example comparison:
| Without “else” | With “else” |
| Who is coming? | Who else is coming? |
| Whom did you see? | Whom else did you see? |
The rule stays identical — only the meaning expands to include “any other person.”
Common mistake: Many people assume “whom else” sounds more formal or “safer,” so they use it even when “who else” is grammatically correct. This is a real and very common error — using “whom” doesn’t automatically make a sentence more correct, only more object-focused.
Why People Confuse “Who Else” and “Whom Else”
This confusion isn’t a sign of poor English — even native speakers struggle with it. Here’s why.
A Brief History of Who vs. Whom
Old English had a rich case system, meaning nouns and pronouns changed form based on their grammatical role (subject, object, possessive, and so on). “Who” and “whom” are two of the last surviving remnants of that system in modern English.
Most other pronoun pairs (like he/him, she/her) survived because they’re short and used constantly. But “whom” is used less often, in more formal contexts, so it has slowly faded from everyday speech over the past century.
Why “Whom” Is Becoming Less Common
Linguists note that in casual American English, “whom” is often replaced by “who,” even in object position. For example, native speakers commonly say “Who did you call?” instead of the technically correct “Whom did you call?”
This happens because:
- “Whom” sounds overly formal or stiff in casual speech.
- Many speakers no longer instinctively apply the subject/object rule for question words.
- “Who” has become the default, all-purpose form in spoken English.
Quick Tip: In formal writing (academic papers, legal documents, professional emails to executives), “whom” still matters. In everyday conversation, texting, or casual writing, “who” is almost always acceptable — and often preferred.
How to Pronounce “Who Else” and “Whom Else”
Pronunciation:
- Who else → HOO els (/huː ɛls/)
- Whom else → HOOM els (/huːm ɛls/)
Both words start with the same “hoo” sound. The only difference is the final consonant: “who” ends open, while “whom” closes with an “m” sound. Native speakers often soften this “m” in fast speech, which is another reason the two words get blurred together in conversation.
Tip to remember: Say them out loud in pairs — “who/he,” “whom/him.” Matching the ending sound helps you remember which one is the subject form and which is the object form.
When to Use “Who Else” (With Examples)
Use “who else” whenever the missing person would be the one doing the action.
Everyday Conversations
- Who else is joining us for dinner?
- Who else knows about this?
- Who else wants coffee?
- Who else thinks this plan is a bad idea?
Formal vs. informal: “Who else” fits naturally into both casual chats and semi-formal conversations. It’s the safe, natural default in spoken English.
Business and Professional Writing
- Who else should be copied on this email?
- Who else is available for the client call tomorrow?
- Who else has reviewed this contract?
- Who else can approve this budget request?
Common collocations: who else knows, who else is coming, who else thinks, who else wants, who else should.
Similar words: who other than this, anyone else, someone else.
When to Use “Whom Else” (With Examples)
Use “whom else” when the missing person is receiving the action, or follows a preposition like “to,” “with,” “for,” or “by.”
Formal Writing
- Whom else did the committee interview?
- Whom else should I address in this letter?
- Whom else did the manager consult before deciding?
Academic and Legal English
- Whom else was the contract sent to?
- Whom else does this policy affect?
- To whom else should the complaint be directed?
Formal vs. informal: “Whom else” belongs almost exclusively in formal or academic writing — legal documents, scholarly papers, official correspondence, and highly polished business writing. In casual speech, it can sound stiff or even pretentious.
Quick Tip: If a sentence with “whom else” sounds unnatural when spoken aloud, you can usually rewrite it with “who else” and be understood just as clearly, especially outside formal writing.
Who Else vs. Whom Else: Side-by-Side Comparison Table
| Feature | Who Else | Whom Else |
| Grammatical role | Subject pronoun | Object pronoun |
| He/Him test | He | Him |
| Common in speech | Very common | Rare |
| Common in writing | Common | Formal writing only |
| Register | Neutral to formal | Strictly formal |
| Example | Who else called? | Whom else did you call? |
| Follows a preposition | No | Yes (e.g., to whom else) |
| Risk of sounding odd | Low | High in casual contexts |
25 Real-Life Examples of Who Else and Whom Else
Who else (subject) examples:
- Who else is going to the concert?
- Who else enjoys hiking on weekends?
- Who else has read this book?
- Who else believes the deadline is unrealistic?
- Who else was in the room during the meeting?
- Who else can help with this project?
- Who else saw the accident happen?
- Who else wants to volunteer this weekend?
- Who else agrees with the new policy?
- Who else knows how to fix this issue?
- Who else applied for the job?
- Who else is planning to attend the wedding?
- Who else called while I was out?
Whom else (object) examples:
- Whom else did you speak with about this?
- Whom else should I thank in my speech?
- Whom else did the board consider for the role?
- Whom else did the teacher praise?
- To whom else did you send the invitation?
- Whom else did the journalist quote in the article?
- Whom else does this decision impact?
- Whom else did they hire last quarter?
- For whom else did you buy a gift?
- Whom else did the police question?
- Whom else did you recommend for the position?
- Whom else did she mention in her report?
Tip to remember: Try the he/him test on each example above. If you can naturally insert “he,” it’s a “who else” sentence. If “him” fits, it’s “whom else.”
Common Mistakes to Avoid
- Using “whom else” to sound smart. Adding “whom” doesn’t automatically make a sentence more correct — it must match the grammar role.
- ❌ Whom else is coming? (Wrong — “he” fits, not “him.”)
- ✅ Who else is coming?
- Using “who else” after a preposition. Prepositions almost always require the object form.
- ❌ To who else did you send this?
- ✅ To whom else did you send this?
- Skipping the he/him test. Guessing instead of testing leads to more errors than any other cause.
- Overcorrecting in casual speech. Using “whom else” in a text message or casual chat can sound unnatural, even if it’s technically correct.
- Confusing “else” placement. “Else” always comes directly after who/whom, never before.
- ❌ Else who is coming?
- ✅ Who else is coming?
Who Else vs. Whom Else in American and British English
Both American and British English follow the same subject/object grammar rule. The real difference is in usage frequency, not grammar.
- American English leans more casual. “Whom else” is largely limited to legal writing, academic papers, and highly formal correspondence.
- British English tends to preserve “whom” slightly longer in formal and journalistic writing, though it’s also declining in everyday speech.
In both dialects, “who else” dominates spoken conversation, while “whom else” survives mainly in writing that follows traditional style guides.
Is “Whom” Still Necessary in Modern English?
This is a fair question, and even grammar experts disagree. Here’s a balanced view:
Arguments for keeping “whom”:
- It preserves grammatical precision, especially in legal and academic writing.
- Style guides like The Chicago Manual of Style and APA still expect correct who/whom usage in formal documents.
- It signals a polished, professional tone when used correctly.
Arguments against it:
- Most native speakers no longer use it consistently in conversation.
- Misusing “whom” (using it incorrectly) sounds worse than simply using “who” everywhere.
- Language naturally evolves, and “whom” is following the same fading path as other old case forms.
Bottom line: “Whom” isn’t dead, but it’s specialized. Know the rule, use it in formal writing, and don’t stress about it in daily conversation.
Formal vs. Informal Usage
| Context | Recommended Choice |
| Texting a friend | Who else |
| Casual conversation | Who else |
| Emails to colleagues | Who else (usually fine) |
| Job application letters | Whom else (if object) |
| Legal contracts | Whom else (if object) |
| Academic essays | Whom else (if object) |
| Journalism (news writing) | Who else (style guides vary) |
| Public speeches | Who else |
Quick Tip: When unsure in a formal document, apply the he/him test rather than guessing based on “how fancy it sounds.”
Alternative Phrases You Can Use Instead
If you’re not confident about who/whom, there are natural ways to sidestep the issue entirely.
Better Natural Alternatives
- Anyone else? (instead of “who else”)
- Any other person? (instead of “whom else”)
- Is there anyone else who…?
- Did you speak with anyone else?
- Was there someone else involved?
When Alternatives Sound More Fluent
In spoken English, native speakers often prefer these alternatives because they avoid the who/whom decision altogether and sound more conversational.
Example rewrite:
- Formal: Whom else did you consult?
- Natural alternative: Did you consult anyone else?
Both are correct, but the second option feels more relaxed and avoids any risk of a grammar mistake.
Synonyms, Similar Words, and Related Phrases
Similar words: anyone else, someone else, any other person, others.
Related phrases: who’s next, anyone in particular, no one else, everyone else.
Opposite phrase: “no one else” (indicates there is nobody additional).
Example with opposite:
- Who else is coming? → No one else is coming.

Frequently Asked Questions (FAQs)
1. Is “whom else” grammatically correct? Yes, “whom else” is correct when the person is the object of the verb or follows a preposition, such as “Whom else did you call?” or “To whom else did you write?” It’s grammatically valid, just less common in casual speech.
2. Is it okay to always use “who else” instead of “whom else”? In casual speech and most everyday writing, yes — many native speakers do this. However, in formal, academic, or legal writing, using “whom else” correctly shows stronger grammatical precision.
3. What’s the easiest way to choose between who else and whom else? Use the he/him test. Replace the unknown person with “he” or “him” in a statement. If “he” fits, use “who else.” If “him” fits, use “whom else.”
4. Does “whom else” sound old-fashioned? It can sound formal or old-fashioned in casual conversation, but it’s still expected in professional, legal, and academic writing where grammatical precision matters.
5. Can “who else” ever be used as an object? No. Grammatically, “who else” should only function as a subject. Using it as an object (especially after a preposition) is considered incorrect in formal writing, though common in casual speech.
Final Thoughts
Choosing between “who else” and “whom else” comes down to one simple test: does the missing person perform the action, or receive it? If “he” fits, use “who else.” If “him” fits, use “whom else.” Adding “else” never changes this rule — it only broadens the question to include additional people.
In everyday conversation, “who else” is almost always the safer, more natural choice. Save “whom else” for formal writing, academic work, and situations involving prepositions like “to” or “for.” With the he/him test and the examples in this guide, you’ll never have to guess again — you’ll simply know.
