If you have ever paused before writing who else or whom else, you are not alone. 🤔 Both forms can sound natural in conversation, but they do not always work in the same grammatical position. The real question is simple: Is the person the subject of the sentence, or is the person receiving an action or following a preposition?
I teach grammar by looking at the job a word does in a sentence. That method works especially well here because who and whom have different roles. Once you learn that role, the choice becomes much easier.
For example, you would say, “Who else wants pizza?” because who is doing the action of wanting. But you might say, “Whom else did you invite?” because the person is receiving the action of invite.

Quick Answer: Who Else or Whom Else? 🎯
Who else is normally correct when the person is the subject of the sentence. Whom else is used when the person is the object of a verb or preposition, although it sounds formal in many everyday sentences.
A quick test is to replace the word with he/she or him/her. If he or she works, choose who. If him or her works, choose whom.
| Expression | Grammatical Role | Example |
|---|---|---|
| Who else | Subject | Who else wants to come? |
| Whom else | Object | Whom else did you call? |
| Who else | Subject | Who else knows about this? |
| Whom else | Object | Whom else should I contact? |
The key is not the word else. The key is the grammatical role of who or whom.
Is Who Else or Whom Else the Same Thing? 💡
No. The two forms can ask about another person, but their grammatical jobs are different.
Who is the subject form. Whom is the object form. The word else simply means “another person” or “another one.”
Consider these sentences:
- Who else called you?
Here, who performs the action of calling. - Whom else did you call?
Here, whom receives the action of calling.
The meaning is closely related, but the sentence structure changes.
Subject vs. Object
A subject usually performs an action.
An object usually receives the action.
| Form | Job | Example | Question to Ask |
|---|---|---|---|
| Who else | Subject | Who else helped you? | Who helped? |
| Whom else | Object | Whom else did you help? | You helped whom? |
| Who else | Subject | Who else arrived? | Who arrived? |
| Whom else | Object | Whom else did she invite? | She invited whom? |
A Simple Test Tip 💡
Remove else from the sentence.
Ask:
Who called?
or
Whom did you call?
If the sentence needs the subject form, use who. If it needs the object form, use whom.
This works because else does not control the grammar. The verb does.
Who Else: Meaning and Correct Use 📝
Who else is used when you are asking about another person who is the subject of the sentence.
It is extremely common in everyday American English. You will hear it in questions, conversations, interviews, classrooms, and informal writing.
When Who Else Is the Subject
Look at:
Who else wants coffee?
The hidden structure is:
Who else wants coffee?
The person represented by who performs the action of wanting.
More examples:
- Who else knows the answer?
- Who else lives here?
- Who else wants to join us?
- Who else can help me?
- Who else saw the accident?
In each sentence, the person is the subject.
More Examples
| Sentence | Role of Who | Result |
|---|---|---|
| Who else called? | Subject | ✅ Correct |
| Who else came to the meeting? | Subject | ✅ Correct |
| Who else knows the password? | Subject | ✅ Correct |
| Who else wants dessert? | Subject | ✅ Correct |
The form who else is also very natural in speech.
You might ask:
“Who else is coming tonight?”
That sounds completely normal.
When Should You Use Whom Else? 📚
Use whom else when the person is the object of a verb or comes after a preposition.
This form is grammatically traditional, but it can sound formal in casual conversation.
For example:
Whom else did you invite?
The subject is you. The action is invite. The person receiving the action is whom else.
Object Position
Compare these two sentences:
Who else invited Maria?
Here, who else performs the action.
Whom else did Maria invite?
Here, Maria performs the action, while whom else receives it.
| Sentence | Subject | Object | Correct Form |
|---|---|---|---|
| Who else called Sam? | Who else | Sam | Who |
| Whom else did Sam call? | Sam | Whom else | Whom |
| Who else helped you? | Who else | You | Who |
| Whom else did you help? | You | Whom else | Whom |
The Him/Her Test 💡
One of the best grammar tests is the he/him test.
Try replacing the word with he or him.
If he works, use who.
If him works, use whom.
For example:
Who else came?
Try:
He came.
That works. So who is correct.
Now:
Whom else did you invite?
Try:
You invited him.
That works. So whom is grammatically correct.
Who Else or Whom Else: Key Differences at a Glance 📊
The central difference is simple: who normally acts as a subject, while whom normally acts as an object.
| Feature | Who Else | Whom Else |
|---|---|---|
| Main role | Subject | Object |
| Replaces | He/she | Him/her |
| Common in speech | Very common | Less common |
| Common in formal grammar | Yes | Yes |
| Example | Who else came? | Whom else did you invite? |
| Basic test | He/she | Him/her |
The word else has the same basic meaning in both forms. It means another person in the group or another possible person.
The difference comes from the grammar around it.
Why Do People Confuse Who Else and Whom Else? 🤔
People confuse these forms because modern spoken English often uses who in places where traditional grammar would expect whom.
That means you may hear:
Who did you invite?
very often.
Traditional grammar would prefer:
Whom did you invite?
The first version is extremely common in everyday American English. The second is more formal.
I once reviewed a short business email where the writer changed every who to whom because they thought whom always sounded smarter. The result was grammatically awkward in several places. That experience reminded me that good grammar is not just about choosing the most formal word. It is about choosing the form that fits the sentence and the context.
Common Sources of Confusion
| Reason | What Happens |
|---|---|
| Fast speech | Speakers often use who for both roles |
| Formal grammar rules | Learners may overuse whom |
| Informal English | Who is common in object questions |
| Autocorrect | Software may suggest an unexpected form |
| Lack of practice | Subject and object roles can be hard to spot |
The safest approach is to examine the sentence instead of guessing from how formal it sounds.
How Do You Know Which Form Is Correct? 🧠
You can usually decide by identifying the subject and object.
Start with the verb.
Ask:
Who is doing the action?
If the answer is the person you are asking about, use who.
Then ask:
Who is receiving the action?
If the answer is the person you are asking about, traditional grammar calls for whom.
Step-by-Step Method
Suppose you have:
___ else did you invite?
Step 1: Find the verb.
The verb is invite.
Step 2: Find the person doing the action.
You did the inviting.
Step 3: Find the person receiving the action.
That person is the missing word.
Therefore:
Whom else did you invite?
Now try:
___ else wants to leave?
The verb is wants.
The missing person performs the action of wanting.
Therefore:
Who else wants to leave?
| Question | Person Doing Action | Person Receiving Action | Correct Form |
|---|---|---|---|
| ___ else called? | Who else | — | Who |
| ___ else did you call? | You | Whom else | Whom |
| ___ else complained? | Who else | — | Who |
| ___ else did she blame? | She | Whom else | Whom |
Who Else or Whom Else in Questions 🗣️
Questions are where this difference appears most often.
When who begins a question and acts as the subject, the structure is straightforward.
Examples:
Who else is coming?
Who else knows?
Who else wants to go?
When the person is the object, traditional grammar uses whom.
Examples:
Whom else did you meet?
Whom else did she contact?
Whom else should we invite?
Everyday vs. Formal English
There is an important practical point here.
In modern American English, who is often used instead of whom, especially in casual speech.
For example:
Who else did you invite?
is very common.
Whom else did you invite?
is more formal.
That does not mean the traditional object form is wrong. It means actual usage has become more flexible.
| Situation | Natural Choice |
|---|---|
| Casual conversation | Who else |
| Text message | Who else |
| Friendly email | Who else |
| Formal writing | Whom else may be preferred |
| Very formal question | Whom else can be appropriate |
Can Who Be Used Instead of Whom? ✅
Yes. In modern informal English, who is often used where traditional grammar would use whom.
For example:
Who else did you invite?
This sentence is widely accepted in ordinary American usage.
The more traditional version is:
Whom else did you invite?
Both can communicate the same basic idea.
The choice depends partly on formality.
A Useful Style Rule
If you are speaking casually, who will usually sound more natural.
If you are writing formal or carefully edited prose, whom may be appropriate when it clearly functions as an object.
| Version | Grammar | Style |
|---|---|---|
| Who else did you invite? | Common modern usage | Natural |
| Whom else did you invite? | Traditional object form | Formal |
| Who else came? | Standard | Natural |
| Whom else came? | Incorrect | — |
Notice that whom else came? is not correct because the person is the subject of came.
Correct vs. Incorrect at a Glance ⚠️
The easiest way to master this topic is to compare complete sentences.
| Sentence | Correct/Incorrect | Why |
|---|---|---|
| Who else wants to come? | ✅ Correct | Who is the subject |
| Whom else wants to come? | ❌ Incorrect | Whom cannot be the subject here |
| Whom else did you invite? | ✅ Correct | Whom is the object |
| Who else did you invite? | ✅ Common modern usage | Who is widely used as an object in informal English |
| Whom else called you? | ❌ Incorrect | The missing person is the subject |
A useful point is that incorrect does not always mean “never heard in real English.” Some forms are common in speech even though traditional grammar labels them differently.
Case Study: A Workplace Email 💼
Imagine a manager sends this message:
“We have already invited Sarah and Mike. Who else should we invite to the meeting?”
This is a natural workplace question.
Why?
The person represented by who else is the subject of should we invite in the sense of the person being considered for invitation. In everyday American English, the sentence sounds natural as written.
A more formal version would be:
“Whom else should we invite to the meeting?”
That version follows the traditional object rule more strictly.
I once edited a team announcement that used whom several times. The writer was trying to sound formal, but the message became stiff. I changed some of the sentences to who, because the audience was a small internal team. The meaning stayed the same, but the message sounded much more natural.
| Workplace Situation | Natural Version | Formal Version |
|---|---|---|
| Asking about attendees | Who else is coming? | Who else is coming? |
| Asking whom to invite | Who else should we invite? | Whom else should we invite? |
| Asking about participants | Who else joined? | Who else joined? |
| Asking about people contacted | Who else did you contact? | Whom else did you contact? |
Grammar Rules Explanation 📘
The traditional rule is based on grammatical case.
Who is the subject form. Whom is the object form.
The subject normally performs the action expressed by the verb. The object normally receives the action.
For example:
Who else called?
Here, who else performs the action of calling.
But:
Whom else did you call?
Here, you perform the action, while whom else receives it.
The same distinction appears with prepositions.
For example:
With whom else did you travel?
Here, whom follows the preposition with.
However, normal modern English often avoids such formal structures. Many speakers would simply say:
Who else did you travel with?
Both styles are used, but they differ in formality.
Most standard grammar references recognize this subject-versus-object distinction while also recognizing that whom is less common in everyday English than it once was.
Correct vs. Incorrect at a Glance
| Sentence | Correct/Incorrect | Why |
|---|---|---|
| Who else arrived? | ✅ Correct | Subject |
| Whom else arrived? | ❌ Incorrect | Object form used as subject |
| Whom else did they hire? | ✅ Traditional/formal | Object |
| Who else did they hire? | ✅ Common modern usage | Who is widely used informally |
| With whom else did you speak? | ✅ Correct | Whom follows a preposition |
Common Mistakes With Who and Whom ⚠️
Mistakes happen for several simple reasons.
1. Fast Typing
People often type the first form that comes to mind.
2. Autocorrect
Phone keyboards may encourage familiar forms.
3. Lack of Knowledge
Some writers never learn the subject-object test.
4. Overcorrection
Others learn that whom is “formal” and start using it everywhere.
That last problem is worth watching. Whom is not automatically better than who.
Common Grammar Confusions
| Confusion | Correct Choice | Basic Rule |
|---|---|---|
| who/whom | Depends | Subject vs. object |
| it’s/its | Depends | Contraction vs. possessive |
| you’re/your | Depends | You are vs. possessive |
| they’re/their/there | Depends | Different meanings |
| who’s/whose | Depends | Who is vs. possession |
I once caught myself typing “whom” into a very casual text just because I had been working on formal grammar all morning. I deleted it and used “who.” The sentence sounded much more natural for the setting.
Specific Wrong Uses
| Wrong Form or Use | What’s Wrong | Correct Form |
|---|---|---|
| Whom else came? | Object form used as subject | Who else came? |
| Who else did you invite? | Traditional grammar prefers whom, though who is common | Whom else did you invite? |
| Whom else wants coffee? | Whom cannot serve as the subject here | Who else wants coffee? |
| Who else did she contact? | Traditional grammar prefers whom | Whom else did she contact? |
| Whom else is available? | Whom is not the subject form | Who else is available? |
Remember that the sentences marked with who in object position are common in modern English. Context and formality matter.
Who Else vs. Whom Else in Different Contexts 🌎
The best choice can depend on where and how you are writing.
Everyday American English tends to favor who. Formal writing may use whom when the object role is clear.
| Context | Which Term to Use | Example |
|---|---|---|
| Everyday conversation | Usually who | Who else is coming? |
| Professional writing | Who or whom | Whom else should we contact? |
| Creative writing | Depends on character and tone | Who else would do that? |
| Social media/texting | Usually who | Who else wants tickets? |
Everyday Conversation
Use who freely when it sounds natural.
Who else wants tacos?
Professional Writing
Consider whom when you want a formal tone and the word is clearly an object.
Whom else should we notify?
But do not force it into every sentence.
Creative Writing
The character’s voice matters.
A formal character might say:
Whom else have you informed?
A casual character might say:
Who else did you tell?
Social Media and Texting
Who else is usually the natural choice.
Who else is obsessed with this song? 🎵
How To Remember the Difference 🧠
Use the he/him trick.
Replace the missing word with he or him.
If he fits, choose who.
If him fits, choose whom.
Example One
Who else called?
Test:
He called.
Correct.
So use who.
Example Two
Whom else did you call?
Test:
You called him.
Correct.
So traditional grammar uses whom.
| Test Word | Correct Form |
|---|---|
| He | Who |
| She | Who |
| Him | Whom |
| Her | Whom |
The Fast Memory Trick
Think:
Who = he/she
Whom = him/her
The final letters can help too:
who → he
whom → him
The ending -m in whom can remind you of him.
Common Phrases With Who Else and Whom Else 💬
There are no major idioms built specifically around these two forms, but several common question patterns appear often in everyday English.
| Phrase | Meaning |
|---|---|
| Who else? | What other person? |
| Who else wants to join? | What other person wants to participate? |
| Who else is coming? | What other person is attending? |
| Who else knows? | What other person knows this information? |
| Whom else should I contact? | What other person should I contact? |
| Whom else did you invite? | What other person did you invite? |
The phrase who else? can even stand alone.
For example:
“I already asked Maria.”
“Who else?”
That means:
“What other person did you ask?”
Synonyms and Natural Alternatives ✨
Sometimes you can avoid the who/whom question altogether.
This can make your writing simpler.
For example:
Who else should I call?
can become:
Who should I call next?
Or:
Whom else should I contact?
can become:
Who is the next person I should contact?
These alternatives can be useful when you want a very clear sentence.
| Alternative | Works When | Does Not Work When |
|---|---|---|
| What other person | You want maximum clarity | The sentence needs a natural question |
| Anyone else | Asking whether another person exists | You need a specific person |
| Another person | Making a statement | Asking a direct who-question |
| Who else | Casual and natural questions | Very formal style may prefer whom |
| The next person | Talking about order | No order is involved |
Why Correct Usage Matters ✍️
Grammar choices affect clarity, tone, and confidence.
In casual conversation, using who instead of traditional whom usually causes no confusion. In formal writing, however, knowing the traditional distinction can help you make deliberate style choices.
A useful writing principle is:
Clear writing should make the meaning easy to see.
That matters in many settings.
| Situation | Why Getting It Right Matters |
|---|---|
| Resume | Shows careful writing |
| Client email | Supports a professional tone |
| Published content | Improves editing quality |
| Social post | Keeps language natural and readable |
The goal is not to sound overly formal. The goal is to communicate clearly.
Is Whom Else Too Formal for Everyday English? 🗣️
Often, yes.
Whom else is grammatically appropriate in traditional object structures, but many people find it formal in casual conversation.
For example:
Whom else did you invite?
is correct in traditional grammar.
But:
Who else did you invite?
sounds much more natural to many American English speakers.
This does not make whom useless. It still appears in formal writing, careful speech, and after certain prepositions.
| Sentence | Tone |
|---|---|
| Who else did you ask? | Casual and natural |
| Whom else did you ask? | Formal |
| Who else is coming? | Natural |
| Whom else is coming? | Incorrect |
The final sentence is important. Formality cannot make an incorrect grammatical role correct.
Is Who Else Always Correct? ⚠️
No.
Who else is correct when the phrase acts as a subject. In object positions, traditional grammar calls for whom, although modern English often uses who.
Compare:
Who else helped you? ✅
Here, who else is the subject.
But:
Whom else did you help? ✅
Here, whom else is the object.
You should not choose who simply because it sounds more familiar. First, check the sentence structure.
Quick Recap Checklist ✅
Use this checklist whenever you are unsure.
| Question | If Yes → Use |
|---|---|
| Is the person doing the action? | Who else |
| Can you replace it with he/she? | Who else |
| Is the person receiving the action? | Whom else in traditional grammar |
| Can you replace it with him/her? | Whom else |
| Is the sentence casual? | Who is often natural |
| Does the word follow a preposition? | Whom is traditional |
Practice Examples
- ___ else wants pizza?
Answer: Who else wants pizza? - ___ else did you invite?
Traditional answer: Whom else did you invite? - ___ else called the office?
Answer: Who else called the office?
The more you practice the subject-object test, the faster the choice becomes.
FAQs About Who vs Whom 🤔
What is the difference between who else and whom else?
Who else is normally used when the person is the subject. Whom else is traditionally used when the person is the object of a verb or follows a preposition.
Is “who else” grammatically correct?
Yes. Who else is grammatically correct when the phrase acts as the subject.
For example:
Who else wants to come?
Here, who else performs the action of wanting.
Is “whom else” grammatically correct?
Yes, when whom functions as an object.
For example:
Whom else did you invite?
Here, whom else receives the action of the verb invite.
Should I say “who else did you invite” or “whom else did you invite”?
Both are used in modern American English. Whom else did you invite? follows the traditional object rule. Who else did you invite? is very common in everyday speech and informal writing.
Who else is coming or whom else is coming?
The correct form is Who else is coming?
The person represented by who else is the subject of is coming.
Whom else should I contact or who else should I contact?
In traditional grammar, Whom else should I contact? is preferred because the person is the object of contact. In everyday American English, Who else should I contact? is also very common.
How can I remember who versus whom?
Use the he/him test. If you can replace the word with he or she, use who. If you can replace it with him or her, use whom.
Is whom still used in American English?
Yes. It is still used, especially in formal writing and after some prepositions. However, who has become very common in places where traditional grammar would use whom.
Is “whom else came” correct?
No. The correct sentence is:
Who else came?
The person who came is the subject, so who is required.
Is “who else did you meet” acceptable?
Yes. Who else did you meet? is very common and natural in modern American English. Traditional formal grammar would use Whom else did you meet? because the person is the object of meet.
Conclusion: Who Else or Whom Else Made Simple 🎯
Who else or whom else becomes much easier once you focus on the role of the word in the sentence. If the person is doing the action, use who. If the person is receiving the action or follows a preposition, traditional grammar uses whom.
The famous he/him test is your fastest tool. If he or she fits, choose who. If him or her fits, choose whom.
At the same time, remember that modern American English often uses who in object questions. That is why “Who else did you invite?” sounds completely normal in everyday conversation, even though traditional grammar prefers “Whom else did you invite?”
Good grammar is not about making every sentence sound stiff. It is about knowing the rule and choosing the form that fits your meaning, audience, and tone. ✨
When you remember who = he/she and whom = him/her, this confusing pair becomes much easier.
Know the role, choose the word, and write with confidence. ✅
