Who else or whom else? This question causes confusion because both forms can appear in English, but they do not serve exactly the same grammatical role. The traditional rule is simple: use who when the pronoun acts as the subject, and use whom when it acts as the object.
The word else means “in addition to the person already mentioned, considered, or implied.” It does not change whether who or whom is grammatically appropriate. So, the real question is not whether you need else, but whether the person represented by the pronoun is doing the action or receiving it.
For example, “Who else is coming?” is correct because “who” is the subject of “is coming.” However, “Whom else did you invite?” follows the traditional objective case because the person represented by “whom” receives the action of “invite.”
Here’s the important part: modern English often uses “who” instead of “whom,” especially in everyday speech and informal writing. That is why you may hear “Who else did you invite?” far more often than “Whom else did you invite?”
The Core Rule Explained Simply
The easiest way to understand who else vs. whom else is to focus on the grammatical job performed by the pronoun.
Who is traditionally used for the subject of a verb. The subject performs the action or occupies the main position in the sentence.
Whom is traditionally used for the object of a verb or preposition. The object receives the action or follows a preposition.
Consider these two sentences:
- Who else wants coffee?
- Whom else did you call?
In the first sentence, “who” performs the action expressed by “wants.” The person is the one who wants coffee.
In the second sentence, “whom” receives the action of “call.” Someone called that person.
The word else simply adds the meaning of “another person” or “another person besides the one already mentioned.”
Use “Who Else” for the Subject
Use who else when the unknown person is the subject of the sentence.
Examples:
- Who else knows the answer?
- Who else wants to join us?
- Who else is attending the meeting?
- Who else can help me?
- Who else lives in this neighborhood?
- Who else remembered the deadline?
In each example, the person represented by “who” is connected directly to the action or state.
For instance, in “Who else knows the answer?”, the hidden structure is:
Who else → knows → the answer
The person is doing the knowing, so who is appropriate.
Use “Whom Else” for the Object
Use whom else when the pronoun functions as the object of a verb or preposition, especially in formal or carefully edited English.
Examples:
- Whom else did you invite?
- Whom else did she contact?
- Whom else should we ask?
- Whom else have they interviewed?
- Whom else did the manager blame?
- With whom else were you traveling?
Take “Whom else did you invite?”
The sentence can be reduced to:
You → invited → whom else
“You” is the subject. “Whom else” is the object. Therefore, whom is the traditional grammatical choice.
Side-by-Side Comparison Table
| Situation | Example | Meaning | Correct Usage |
| Subject of the verb | Who else is coming? | Which other person is coming? | Who else |
| Subject of the verb | Who else knows? | Which other person knows? | Who else |
| Object of a verb | Whom else did you call? | Which other person did you call? | Whom else |
| Object of a verb | Whom else did she invite? | Which other person did she invite? | Whom else |
| Object in casual English | Who else did you call? | Same basic meaning | Who else is common |
| Object after a preposition | With whom else did you speak? | Which other person did you speak with? | Whom else in formal style |
| Subject after “else” | Who else wants lunch? | Which other person wants lunch? | Who else |
| Formal object | To whom else should I send it? | Which other person should receive it? | Whom else |
Deep Dive Into “Who Else”
Who else is the more straightforward form because who is the normal subject form of the interrogative pronoun.
You use it when you are asking about another person who performs an action, experiences something, or occupies the subject position.
When Should You Use “Who Else”?
Use who else when the answer would naturally be a subject pronoun such as he, she, or they.
Look at this:
Who else wants dessert?
You can test it by replacing “who” with a known pronoun:
She wants dessert.
Because she works, the traditional interrogative form is who.
Another example:
Who else called you?
Test it:
He called me.
Because “he” is a subject pronoun, who is the traditional choice.
Here are more examples:
- Who else is available?
- Who else can solve this problem?
- Who else attended the lecture?
- Who else wants to volunteer?
- Who else understands the instructions?
- Who else noticed the mistake?
- Who else lives here?
- Who else will be responsible for this project?
“Who Else” in Questions
The phrase appears especially often in questions because speakers frequently want to identify an additional person.
For example:
Who else is going to the party?
This asks for the identity of another person or group of people who will attend.
Similarly:
Who else knows about the plan?
Here, “who” is the subject of “knows.”
The construction remains the same even when the sentence becomes more complicated:
Who else do you think will attend?
The important grammatical point is that “who” is the subject of will attend, even though it appears inside a longer question.
That distinction can prevent many mistakes.
Quick Test for “Who Else”
Try replacing the phrase with he, she, or they.
If the replacement works naturally as the subject, choose who else.
Who else wants to come?
Test:
She wants to come.
Therefore:
Who else wants to come?
Another example:
Who else knows the truth?
Test:
They know the truth.
Therefore:
Who else knows the truth?
This test is especially useful when a sentence looks complicated.
Quick Test Checklist
Ask yourself:
- Is the person doing the action?
- Can I replace the person with he, she, or they?
- Does the pronoun function as the subject?
- Is the question asking who performs the action?
If the answer is yes, who else is the traditional choice.
Deep Dive Into “Whom Else”
Whom else is the traditional objective form. It is used when the person being identified is the object of a verb or preposition.
It can sound formal because modern everyday English frequently uses who in places where traditional grammar would prescribe whom.
Consider:
Whom else did you invite?
The structure is:
You = subject
invited = verb
whom else = object
The person does not act inviting. The person receives the action.
When Should You Use “Whom Else”?
Use whom else when the person is the object of a verb.
Examples include:
- Whom else did you meet?
- Whom else did they hire?
- Whom else should I contact?
- Whom else have you told?
- Whom else did the teacher question?
- Whom else can we trust?
In each sentence, the pronoun represents someone who is being met, hired, contacted, told, questioned, or trusted.
Let’s make this concrete.
Whom else did Maria invite?
The underlying statement might be:
Maria invited him.
Because him is the object form, traditional grammar calls for whom.
“Whom Else” After a Preposition
The distinction becomes especially clear after a preposition.
Examples:
- With whom else did you speak?
- To whom else should I send the document?
- For whom else was the package intended?
- From whom else did you receive the information?
- About whom else were they talking?
The pronoun follows a preposition such as with, to, for, from, or about.
In formal writing, whom is traditionally preferred after these prepositions.
For example:
With whom else did you travel?
The underlying statement is:
You traveled with him.
Because “him” is the objective form of “he,” the traditional question uses whom.
But Is “Who Else” Ever Used as an Object?
Yes. This is where modern English creates confusion.
In everyday speech, people commonly say:
Who else did you invite?
Rather than:
Whom else did you invite?
The first version is widespread and natural in contemporary English. Many speakers reserve whom for formal situations or fixed constructions.
Therefore, there are two separate questions:
What does traditional grammar prescribe?
For an object, it prescribes whom.
What does modern English commonly use?
Modern English frequently uses who for both subject and object, particularly in informal contexts.
This means “Who else did you invite?” is common contemporary English, while “Whom else did you invite?” is the more traditionally formal construction.
The Meaning Shift or Nuance
The meaning of who else and whom else is usually not significantly different.
Both can refer to another person or additional people.
The primary difference is grammatical function and level of formality, not the basic meaning.
Compare:
Who else is coming?
This asks which additional person is coming.
Whom else did you invite?
This asks which additional person was invited.
The word else carries the idea of addition.
For example, if someone has already mentioned Sarah, you might ask:
Who else is attending?
That means:
Which other person is attending besides Sarah?
Likewise:
Whom else did you tell?
means:
Which other person did you tell besides the person already discussed?
The subtle distinction comes from the role of the pronoun, not from the word else.
“Else” Does Not Determine Who or Whom
A common misconception is that adding else somehow changes the grammatical case.
It does not.
Compare:
Who is coming?
becomes:
Who else is coming?
The grammatical role remains subject.
Likewise:
Whom did you invite?
becomes:
Whom else did you invite?
The grammatical role remains object.
So, think of else as an additional meaning word. It does not determine the pronoun form.
Why the Confusion Persists
The who vs. whom distinction has become less obvious because English has changed considerably over time.
Older formal grammar strongly emphasized the distinction between subjective and objective pronouns. Traditional pairs include:
- he / him
- she / her
- they / them
- who / whom
Modern English, however, increasingly favors simpler structures. In ordinary conversation, who often replaces whom, particularly when the sentence does not sound formal.
This creates a gap between traditional grammar rules and everyday usage.
For example, many speakers naturally say:
Who did you see?
rather than:
Whom did you see?
The same pattern appears with else:
Who else did you see?
is extremely common.
Another reason for the confusion is that English speakers rarely pronounce the distinction clearly in rapid conversation. Written grammar can preserve distinctions that ordinary speech has weakened.
There is also an educational issue. Many people learn the rule as “use whom for objects,” but they are not always taught how to identify an object inside a complicated sentence.
As a result, people may choose whom simply because a sentence sounds formal, even when who is grammatically required.
For example:
Whom else is coming?
sounds formal, but it is traditionally incorrect because the pronoun is the subject of “is coming.”
The correct traditional form is:
Who else is coming?
Formal vs. Casual Contexts
Context matters when deciding whether to use who else or whom else.
In casual conversation, who is overwhelmingly comfortable for many speakers.
You might naturally hear:
Who else is coming?
Who else did you invite?
Who else should I call?
These sound normal and conversational.
In formal writing, however, whom can be useful when the pronoun clearly functions as an object.
For example:
Whom else should the committee consult before making its decision?
This construction has a formal tone.
Similarly:
To whom else should the application be addressed?
is more formal than:
Who else should I address the application to?
Both can communicate the intended idea, but the first follows traditional formal grammar more closely.
Academic and Professional Writing
In academic writing, professional correspondence, legal writing, and formal reports, maintaining the traditional who/whom distinction can demonstrate grammatical precision.
For example:
Whom else did the researchers interview?
is traditionally precise.
However, writers should avoid forcing whom into every question simply to sound sophisticated.
Whom else is responsible? is not improved by its formality. Since “whom” would be the subject, who else is the appropriate traditional construction.
The goal is not to use the most formal-looking word.
The goal is to use the grammatically appropriate form.
Case Studies and Pop Culture Examples
Real-world English demonstrates how strongly who has become established in everyday object questions.
Consider common conversational questions such as:
Who did you call?
Who did you see?
Who else is coming?
Who else did you tell?
These constructions are widespread because modern English often treats who as the default interrogative pronoun.
In edited and highly formal contexts, you may still encounter whom:
Whom did you contact regarding the matter?
The difference illustrates a broader linguistic trend. English often preserves older grammatical forms in formal writing while simplifying them in conversation.
Academic Example
Imagine a research report discussing interviews:
Whom else did the researchers interview after selecting the initial participants?
Here, “whom” is the object of “interview.”
A less formal version might say:
Who else did the researchers interview after selecting the initial participants?
The meaning remains essentially unchanged.
Workplace Example
Imagine a manager asking about a project:
Who else is working on this assignment?
This uses who because the unknown people are the subjects of “is working.”
Now compare:
Whom else should I contact about the assignment?
The unknown person is the object of “contact,” so traditional formal grammar uses whom.
Everyday Conversation
A friend might ask:
Who else did you invite to dinner?
Almost no one would find this unusual.
A very formal version would be:
Whom else did you invite to dinner?
Both communicate the same basic idea, but their styles differ.
Advanced Scenarios and Flowchart
When the sentence becomes complicated, use a step-by-step approach instead of relying on what sounds formal.
Decision flowchart:
Start with the phrase containing who else / whom else.
↓
Ask: What is the pronoun doing in the sentence?
↓
If it is the subject, use who else.
↓
If it is the object of a verb, traditional formal grammar uses whom else.
↓
If it follows a preposition, traditional formal grammar uses whom else.
↓
Now consider the context.
↓
If the writing is casual or conversational, who else is widely used even as an object.
↓
If the writing is formal and you want to follow the traditional distinction, choose whom else for an object.
Advanced Example 1
Who else do you think will win?
This can look confusing because “who else” appears before “do you think.”
Ignore the interrupting phrase:
Who else will win?
“Who else” is the subject of “will win,” so who is correct.
Advanced Example 2
Whom else do you think the committee will interview?
Ignore the parenthetical-looking phrase:
The committee will interview whom else.
The person is the object of “interview.”
Therefore, the traditional form is whom else.
Advanced Example 3
Who else do you believe understands the problem?
Simplify it:
Who else understands the problem?
The pronoun is the subject of “understands.”
Therefore:
Who else is correct.
Advanced Example 4
Whom else did the professor say the students should contact?
The structure is more complicated, but the underlying question is:
The students should contact whom else.
Therefore, under traditional grammar:
Whom else.
This method is more reliable than simply choosing the form that sounds more formal.
Quick Reference Table
| Use | Example |
| Who else as subject | Who else is coming? |
| Who else as subject | Who else knows the answer? |
| Whom else as object, formal | Whom else did you invite? |
| Whom else after a preposition, formal | With whom else did you speak? |
| Who else as a common modern object form | Who else did you invite? |
| Who else in casual speech | Who else should I call? |
Common Mistakes That Lower Quality
Even experienced writers can become uncertain when who and whom appear inside longer questions.
Mistake 1: Using “Whom” Because It Sounds Formal
Whom else is coming to the meeting?
Traditional grammar does not support this construction because “whom” is the subject.
Use:
Who else is coming to the meeting?
Formal language is not automatically correct language.
Mistake 2: Assuming “Who Else” Is Always Correct
Modern English often accepts who in object positions, but formal traditional grammar still distinguishes the objective form.
For example:
Whom else did the director interview?
is the traditional formal choice.
If the context demands careful adherence to traditional grammar, automatically using who may be less precise.
Mistake 3: Thinking “Else” Changes the Case
It does not.
Compare:
Who is responsible?
and:
Who else is responsible?
Both use the subject form.
Likewise:
Whom did you contact?
and:
Whom else did you contact?
Both use the traditional object form.
Mistake 4: Ignoring the Verb
Look at the relationship between the pronoun and the verb.
Who else helped you?
The unknown person performed the helping.
Whom else did you help?
The unknown person received the helping.
That single difference changes the traditional grammatical form.
Mistake 5: Using “Whom” After Every Preposition Without Checking the Sentence
After a preposition, whom is traditionally appropriate when the pronoun is its object.
But some modern constructions move the preposition to the end:
Who else did you speak with?
This is natural modern English.
The more formal alternative is:
With whom else did you speak?
Both are understandable, but they belong to different stylistic patterns.
Mistake 6: Confusing “Who Else” With “Who’s Else”
Who’s else is not the correct replacement for who else.
“Who’s” normally means who is or who has.
For example:
Who’s coming?
means:
Who is coming?
But:
Who else is coming?
uses who else, not “who’s else.”
Memory Hacks That Actually Work
You do not need to memorize a complicated grammar chart.
Use these practical shortcuts.
Hack 1: He or Him
Replace the unknown person with he or him.
If he works, use who.
If him works, traditional grammar uses whom.
Example:
Who else called?
Test:
He called.
Therefore, who.
Now:
Whom else did you call?
Test:
You called him.
Therefore, whom.
Hack 2: Think “Who Does, Whom Receives”
Remember:
Who = does the action
Whom = receives the action
For example:
Who else wrote the report?
The person wrote it, so use who.
Whom else did you ask?
The person was asked, so traditional grammar uses whom.
Hack 3: Remove “Else”
If else is distracting you, temporarily remove it.
Who else is waiting?
becomes:
Who is waiting?
That is clearly who.
Similarly:
Whom else did she invite?
becomes:
Whom did she invite?
The underlying structure becomes easier to recognize.
Hack 4: Use the “He/Him” Test
This is perhaps the most reliable traditional test.
Who else wants pizza?
He wants pizza.
Therefore, who.
Whom else did you invite?
You invited him.
Therefore, whom.
Hack 5: Do Not Confuse Formality With Correctness
A useful rule is:
Never choose “whom” simply because it sounds sophisticated.
First determine the grammatical function.
Then consider the context.
That two-step process prevents many errors.
Why Precision Matters for SEO and Authority
Grammar accuracy matters when you are producing content designed to educate readers, rank in search engines, or establish authority.
A page explaining who else or whom else must be especially careful because readers are actively looking for a reliable answer. If the explanation contradicts its own examples, the content loses credibility.
Clear grammar also improves reader trust. Visitors want explanations that are easy to understand and practical enough to apply immediately.
For SEO content, clarity matters because readers often scan rather than read every sentence. Short explanations, examples, comparison tables, and quick tests make the information easier to process.
Using who else and whom else correctly also allows writers to explain an important distinction between traditional grammar and modern usage.
That distinction is valuable because English is not frozen. A grammar guide should explain both the traditional rule and the way contemporary speakers actually use the language.
For example, telling readers simply that “who else did you invite?” is wrong would be misleading as a description of modern English usage. The sentence is extremely common and natural in contemporary speech.
A more precise explanation is this:
“Whom else did you invite?” follows the traditional objective-case rule, while “Who else did you invite?” is widely used in modern English, especially in informal contexts.
That explanation gives readers useful information without pretending that everyday English follows only older grammatical conventions.
Good grammar content should therefore do more than label a sentence right or wrong. It should explain why the form works, where it is used, and how context affects the choice.
A Quick Quiz
Fill in each blank with who else or whom else according to traditional grammar.
1. ______ is joining us for dinner?
2. ______ did you invite to the wedding?
3. ______ knows about the new schedule?
4. With ______ did the manager discuss the proposal?
5. ______ should we ask for advice?
6. ______ do you think will lead the team?
7. ______ did the researcher interview?
8. ______ wants to volunteer for the project?
Quiz Answers
1. Who else
“Who” is the subject of “is joining.”
2. Whom else
“Whom” is the object of “invite” in traditional grammar.
3. Who else
“Who” is the subject of “knows.”
4. Whom else
The pronoun follows the preposition “with,” so whom is the traditional formal choice.
5. Whom else
The implied structure is “We should ask whom else,” making the pronoun the object of “ask.”
6. Who else
The underlying question is “Who else will lead the team?” The pronoun is the subject of “will lead.”
7. Whom else
The researcher interviewed the person, so the pronoun is the object of “interview.”
8. Who else
The person represented by the pronoun is the subject of “wants.”
The key distinction is simple: who else traditionally refers to a subject, while whom else traditionally refers to an object. In modern English, however, who else is also widely used for objects, especially in casual conversation. When writing formally, use the traditional who/whom distinction when the grammatical role is clear. When speaking naturally, who often sounds more conversational and is extremely common.
The safest approach is to identify the pronoun’s grammatical role first, then consider the level of formality. If the person acts, choose who else. If the person receives the action or follows a preposition, traditional formal grammar favors whom else. Once you learn to use the he/him test, the difference becomes much easier to recognize.
Who else = subject.
Whom else = traditional object.
Who else = also common for objects in modern English.
Conclusion
Understanding who else vs. whom else becomes much easier once you focus on grammatical function instead of formality. Use who else when the person is the subject of the sentence, as in “Who else is coming?” or “Who else knows the answer?” In traditional grammar, use whom else when the person is the object of a verb or follows a preposition, as in “Whom else did you invite?” or “With whom else did you speak?” The word else does not change the grammatical case. It simply adds the meaning of another person or an additional person.
Modern English adds an important layer to this rule. In everyday conversation and informal writing, who is frequently used instead of whom, even when it functions as an object. That makes “Who else did you invite?” perfectly natural in contemporary usage, while “Whom else did you invite?” follows the traditional formal distinction. When precision matters, use the he/him test: if “he” works, choose who; if “him” works, traditional grammar favors whom. Most importantly, do not choose “whom” simply because it sounds more sophisticated. Identify the grammatical role first, then consider the context and level of formality.
Frequently Asked Questions
Is “who else” grammatically correct?
Yes, “who else” is grammatically correct when the pronoun functions as the subject. For example, “Who else is attending the meeting?” is correct because “who” is the subject of “is attending.” Modern English also commonly uses “who else” when the pronoun functions as an object, especially in casual conversation and informal writing.
Is “whom else” grammatically correct?
Yes, “whom else” is grammatically correct when “whom” functions as an object under the traditional rules of English grammar. For example, “Whom else did you contact?” uses “whom” as the object of “contact.” It can also follow a preposition, as in “With whom else did you speak?” This form is particularly associated with formal writing.
Should I say “who else did you invite” or “whom else did you invite”?
Both forms are encountered in English, but they reflect different usage patterns. “Whom else did you invite?” follows the traditional objective-case rule because the person receives the action of “invite.” “Who else did you invite?” is extremely common in modern English and sounds natural in everyday conversation. For formal traditional grammar, choose “whom.”
Is “who else is coming” or “whom else is coming” correct?
“Who else is coming?” is the correct traditional construction. Here, “who” is the subject of the verb phrase “is coming.” The person represented by “who” performs or experiences the action described by the sentence. “Whom else is coming?” is incorrect under the traditional subject-object distinction because “whom” is an object form.
How can I quickly remember who vs. whom?
Use the he/him test. Replace the unknown person with “he” or “him.” If he works, choose who. If him works, traditional grammar favors whom. For example, “Who else called?” becomes “He called,” so “who” is correct. “Whom else did you call?” becomes “You called him,” so “whom” is traditionally correct.
Does the word “else” change whether I use who or whom?
No. “Else” does not determine whether you need who or whom. It simply means another person, additional people, or someone besides the person already mentioned or understood. Remove “else” temporarily if it makes the sentence confusing. Compare “Who is coming?” with “Who else is coming?” and “Whom did you invite?” with “Whom else did you invite?”
Is “who else” more common than “whom else”?
In contemporary English, “who else” is generally more common, particularly in speech and informal writing. Speakers frequently use “who” where traditional grammar would prescribe “whom.” This pattern is especially noticeable in questions such as “Who else did you tell?” and “Who else should I contact?” Formal writing may retain “whom” when the objective role is clear.
Should I use “whom” in formal writing?
You can use “whom” in formal writing when it functions as an object, especially when following a traditional grammatical style. For example, “Whom else should the committee consult?” follows the traditional rule. However, formality does not mean using “whom” everywhere. If the pronoun is the subject, who remains appropriate, as in “Who else should attend?”
What is the difference between “who else” and “whom else”?
The traditional difference is grammatical case. “Who else” is used when the person is the subject, while “whom else” is used when the person is the object of a verb or preposition. Their basic meaning is otherwise similar because else means another or additional. Modern English often uses “who” for both roles, particularly in informal contexts.
Is “who else did you see” acceptable?
Yes. “Who else did you see?” is widely used and natural in modern English, particularly in conversation and informal writing. Under the traditional grammatical distinction, “whom else” would be preferred because the person is the object of “see.” Therefore, “Whom else did you see?” is the traditional formal version, while “Who else did you see?” reflects common contemporary usage.
