Who Else vs Whom Else can seem confusing when choosing between who else and whom else, especially for English learners and confident writers. The classic debate around who, whom, who else, and whom else becomes easier when you understand the subject and object roles.
In English grammar, the subject performs an action, while the object receives the action. A tiny letter m can shift the entire structure of a sentence, creating sparks hesitation and leaving you wondering which version belongs. As a native English speaker, I remember the first time I typed the phrase in a professional email, second-guessed my choice, and paused before checking the correct usage.
For example, who else may be coming or attending a meeting, while whom else can applies when someone is the object who receives the action. Understanding parts of speech, verbs, object form, and sentence shapes helps make your sentences more simple, accurate, and clear.
Quick Answer
Who else and whom else can both be grammatically correct. The correct choice depends on the grammatical role of the pronoun.
- Use who else when the person is the subject of the clause.
- Use whom else when the person is traditionally treated as the object of the clause or follows a preposition in formal English.
- In everyday American English, who else is often used even where traditional grammar would recommend whom else.
- The word else doesn’t change whether the pronoun should be who or whom.
- The easiest traditional test is to replace the word with he/she/they or him/her/them.
Consider these examples:
Who else wants to come?
Here, the unknown person is doing the wanting. Therefore, who functions as the subject.
Whom else did you invite?
Here, the unknown person receives the action of invite. Therefore, traditional grammar uses whom.
In normal conversation, however, you’ll commonly hear:
Who else did you invite?
That version is extremely natural in contemporary English. It isn’t helpful to treat every use of who in this position as a serious error.
Comparison Overview
The quickest way to understand who else vs whom else is to compare their grammatical functions.
| Feature | Who else | Whom else |
| Traditional role | Subject | Object |
| Basic substitute | He, she, they | Him, her, them |
| Common in conversation | Very common | Less common |
| Common in informal writing | Very common | Uncommon |
| Common in formal writing | Common when functioning as subject | Preferred when functioning as object |
| Example | Who else knows? | Whom else did you call? |
| After a preposition | Often used in conversational English | Traditional formal choice |
The important thing isn’t simply whether the sentence sounds formal. Grammar comes first. Formality matters after you identify the grammatical role.
For example, “Who else arrived?” is correct because the person represented by who performs the action of arriving.
By contrast, “Whom else did you call?” uses whom because the person receives the action of calling.
Main Differences Between Who Else vs Whom Else
The main difference between who else vs whom else comes down to subject versus object.
1. Who Else Functions as a Subject
A subject performs the action described by the verb.
Consider:
Who else wants coffee?
The unknown person is the one who wants coffee. If you replace who with a known pronoun, you could say:
She wants coffee.
Because she is a subject pronoun, who is traditionally correct.
The same pattern appears in many everyday questions:
- Who else knows the answer?
- Who else wants to participate?
- Who else lives here?
- Who else called this morning?
- Who else can help us?
- Who else remembers the meeting?
In every example, the person represented by who performs the action or occupies the subject position.
2. Whom Else Functions as an Object
An object receives an action or appears after a preposition.
For example:
Whom else did you invite?
The person represented by whom doesn’t perform the action. You perform the action of inviting. The other person receives that action.
Compare the structure:
You invited him.
Here, you is the subject and him is the object. Therefore:
Whom else did you invite?
Traditional grammar follows the same pattern.
Other examples include:
- Whom else did you contact?
- Whom else did she interview?
- Whom else should we ask?
- Whom else did they choose?
- Whom else did he meet?
3. “Else” Doesn’t Change the Grammar
This point often gets overlooked.
The word else means something like “in addition to the person or people already mentioned or considered.” It doesn’t change whether the pronoun acts as a subject or object.
Compare:
Who knows?
and
Who else knows?
The addition of else doesn’t change the grammatical role of who.
Likewise:
Whom did you invite?
becomes:
Whom else did you invite?
Again, else adds meaning but doesn’t change the pronoun’s grammatical function.
What Does “Who Else” Mean?
Who else asks about another person or additional people beyond someone already known, mentioned, or implied.
For example:
Sarah is coming. Who else is coming?
The question asks about additional people besides Sarah.
You can use who else when asking about people who:
- know something
- want something
- did something
- can do something
- are present
- are participating
- have an opinion
- may be responsible
- might attend
Here are some natural examples:
Who else knows about the plan?
Who else wants to order lunch?
Who else was at the office?
Who else can solve this problem?
Who else remembers what happened?
Notice that who serves as the subject in these examples.
Common “Who Else” Patterns
Certain sentence structures appear frequently in everyday English.
| Pattern | Example |
| Who else + verb? | Who else knows? |
| Who else + auxiliary + verb? | Who else can help? |
| Who else + be verb? | Who else is coming? |
| Who else + past verb? | Who else called? |
| Who else + modal verb? | Who else might attend? |
These patterns are worth learning because they occur naturally in conversation.
What Does “Whom Else” Mean?
Whom else refers to another person who functions as an object in a sentence.
For example:
Whom else did you contact?
The grammatical structure is:
You → contacted → whom else
The subject is you. The verb is contacted. The object is whom else.
The same principle applies here:
Whom else should we invite?
The implied structure is:
We → should invite → whom else
Because the unknown person receives the action, traditional grammar uses whom.
Examples of “Whom Else”
- Whom else did you meet?
- Whom else did she call?
- Whom else should I ask?
- Whom else did they interview?
- Whom else would you recommend?
- Whom else did the manager select?
These sentences are grammatically clear under the traditional subject-object distinction.
The He/Him Test for Who Else vs Whom Else
One of the most useful traditional methods is the he/him test.
Remove else and ask which pronoun would naturally answer the question.
If he, she, or they works, choose who.
If him, her, or them works, choose whom in traditional grammar.
Example 1: Who Else
Who else called you?
Answer:
He called me.
Because he works, who is appropriate.
Example 2: Whom Else
Whom else did you call?
Answer:
I called him.
Because him works, traditional grammar calls for whom.
A Simple Formula
Who → he/she/they
Whom → him/her/them
This test isn’t perfect for every complicated sentence. Still, it gives you a practical shortcut for most ordinary examples.
When to Use “Who Else”
Use who else when the person is the subject of the clause.
Who Else as the Subject
Consider:
Who else wants to join us?
The person does the wanting.
Who else knows the password?
The person does the knowing.
Who else arrived early?
The person performs the action of arriving.
Who else can answer this question?
The person performs the action of answering.
This distinction remains the same even when the verb changes.
Who Else in Everyday Conversation
In ordinary American English, who else is extremely natural.
Imagine a group of coworkers discussing lunch:
“I’m getting pizza. Who else wants some?”
Nobody needs a formal grammar lecture to understand that question. It sounds natural because who is functioning as the subject of wants.
You can also hear the phrase in situations involving curiosity:
“John already knows. Who else knows?”
Or surprise:
“You invited Maria? Who else did you invite?”
The last example introduces an important distinction. Traditional grammar would favor whom else because whom functions as the object of invite. Yet who else did you invite? is extremely common in modern English.
When to Use “Whom Else”
Use whom else when you want the traditional object form, especially in formal or carefully edited writing.
Whom Else as a Direct Object
Consider:
Whom else did the committee interview?
The committee performs the interviewing. The person receives the action.
Another example:
Whom else should we contact?
The implied structure is:
We should contact him.
Therefore, whom fits the traditional object pattern.
Whom Else After a Preposition
Traditional grammar also uses whom after a preposition.
Examples include:
- To whom else
- With whom else
- For whom else
- By whom else
- From whom else
For example:
To whom else should I send the documents?
The preposition to is followed by the object whom.
Another example:
With whom else are you traveling?
Here, whom follows the preposition with.
These constructions sound formal, but they’re grammatically established.

This is where formal and conversational English often diverge.
Traditional formal English:
With whom else are you working?
Conversational English:
Who else are you working with?
Both sentences communicate the same basic idea. The difference comes from style and grammatical tradition.
In the second sentence, with appears at the end. This is called preposition stranding, a normal feature of English.
Compare:
To whom did you speak?
with:
Who did you speak to?
The first sounds formal. The second sounds natural in everyday American English.
Therefore, you shouldn’t assume that conversational English is automatically wrong simply because it doesn’t follow the most formal construction.
Is “Who Else Did You Invite?” Correct?
Yes, “Who else did you invite?” is widely used and natural in modern English.
Traditional grammar would analyze who as an object in this sentence and therefore recommend:
Whom else did you invite?
However, modern English has weakened the distinction between who and whom in many contexts. Speakers commonly use who where traditional grammar would prescribe whom.
This is especially common when who appears at the beginning of a question.
Therefore, the choice can depend on the setting:
| Situation | Natural choice |
| Casual conversation | Who else did you invite? |
| Text message | Who else did you invite? |
| Informal email | Who else did you invite? |
| Formal edited prose | Whom else did you invite? may be preferred |
| Very formal construction | Whom else did you invite? |
The key is not to label ordinary modern usage as automatically incorrect.
Is “Whom Else Did You Invite?” Correct?
Yes. “Whom else did you invite?” is grammatically correct under traditional English grammar.
Here, whom is the direct object of invite.
You can verify this with the substitution test:
You invited him.
Because him is the object form, whom fits the traditional rule.
The sentence may sound more formal than “Who else did you invite?” However, formal does not mean wrong or unnatural. In carefully edited writing, whom can communicate grammatical precision.
Who Else vs Whom Else in Formal and Informal English
The traditional distinction still matters, but English usage has changed.
Informal English
In conversation, texting, casual emails, and everyday communication, who is often the more natural choice.
Examples:
- Who else is coming?
- Who else did you call?
- Who else did you invite?
- Who else are you meeting?
Using whom in every object position can make casual speech sound unusually formal.
Formal English
Formal writing may preserve the traditional distinction more consistently.
Examples:
- Whom else did the committee contact?
- To whom else should the report be sent?
- With whom else did the researcher collaborate?
Still, formal writing doesn’t mean that every sentence must contain whom. If the pronoun functions as a subject, who remains correct.
Who else participated in the study?
Making that sentence “Whom else participated in the study?” would be incorrect because the pronoun is the subject.
Common Mistakes With Who Else and Whom Else
Understanding the most frequent mistakes can make the rule much easier to remember.
Mistake 1: Using “Whom” Just to Sound Formal
Some writers assume whom always sounds more educated.
That’s not how the grammar works.
Whom else arrived first?
This is incorrect under the traditional subject-object distinction because whom is the subject of arrived.
The correct form is:
Who else arrived first?
Mistake 2: Assuming Every Question Needs “Who”
The opposite mistake happens too.
Who else did you contact?
This is common modern English, but traditional formal grammar analyzes whom as the object:
Whom else did you contact?
So the grammatical distinction still has value even though everyday usage often favors who.
Mistake 3: Thinking “Else” Determines the Choice
It doesn’t.
Compare:
Who else came?
and
Whom else did you invite?
The word else has the same basic function in both sentences. The difference comes from the grammatical role of who/whom.
Mistake 4: Ignoring the Entire Sentence
Don’t choose who or whom based only on the word immediately following it.
Look at the whole clause.
For example:
Who else can help?
The person is the subject.
But:
Whom else can we ask?
The person is the object of ask.
The modal verb can appears in both sentences. Yet the pronouns perform different grammatical jobs.
FAQs:
Is “Who Else” or “Whom Else” correct?
“Who else” is correct in most everyday situations. Use it when the phrase acts as the subject, such as “Who else is coming?”
When should I use “Whom Else”?
Use “whom else” when the phrase functions as an object, especially after a preposition. For example, “To whom else should I send the report?”
Do people commonly use “Whom Else”?
Not usually in everyday English. Most speakers naturally choose “who else”, even in situations where traditional grammar might suggest “whom else.”
Is “Who Else” more common in modern English?
Yes. “Who else” is far more common in modern English, particularly in conversation, emails, messages, and other informal writing.
How can I remember the difference between “Who Else” and “Whom Else”?
Ask whether the phrase performs the action or receives the action. If it performs the action, use “who else.” If it receives the action or follows a preposition, “whom else” may be appropriate.
Conclusion:
Who Else vs Whom Else becomes easier when you focus on the role of the word in the sentence. Who else is the natural choice in most modern English, while whom else is mainly used in formal contexts or when strict grammatical precision matters.
For everyday conversations, emails, and messages, who else will usually sound clearer and more natural. When you need formal correctness, check whether whom else functions as the object or follows a preposition.
