Who Else or Whom Else? Correct Version With Examples

If you’ve ever paused over “Who else?” and “Whom else?”, the confusion is understandable. Both forms contain familiar words, but who and whom have different grammatical roles in traditional English. The good news is that the choice becomes much easier once you look at what the pronoun does in the sentence. In modern American English, “who else” is by far the more natural choice in ordinary questions and conversation. “Whom else” still has a place when whom functions as an object, particularly in formal writing or in a construction with a preposition. Cambridge Dictionary describes whom as the object form of who and notes that it appears more often in formal writing than in speech.

The important point is this: “who else” isn’t simply the casual version, and “whom else” isn’t automatically the more correct version. Grammar depends on the role of the pronoun. Modern usage also matters. In many sentences where traditional grammar might favor whom, contemporary English commonly uses who, especially when the preposition comes at the end.

Who Else or Whom Else: Which One Is Correct?

For most everyday questions, choose “who else.”

Consider these examples:

• Who else is coming to the meeting?
• Who else wants some coffee?
• Who else knows the answer?
• Who else can help us?
• Who else did you invite?

These sentences sound natural because who else is the form English speakers commonly use when asking about another person or additional people. Cambridge specifically gives examples of who being used both as a subject and as an object in questions, including forms such as “Who did you meet?”

Now compare that with:

Whom else did you invite?

Traditional grammar can defend this sentence because the person represented by whom receives the action of inviting. Yet the sentence sounds noticeably more formal to many modern speakers.

A useful comparison is:

Expression	Typical use	Tone	Example
Who else	Everyday questions and speech	Natural	Who else is coming?
Whom else	Formal object construction	Formal	Whom else did you invite?
Who else with a trailing preposition	Modern conversational English	Natural	Who else did you speak to?
Whom else after a preposition	Formal English	Very formal	To whom else did you speak?

So if your goal is clear, natural American English, “who else” is usually the safer choice.

The simplest rule

Use “who else” for normal modern English. Use “whom else” when formal grammar calls for an object form, especially after a preposition.

That rule covers most real-world situations without forcing you to memorize a complicated grammar chart.

What Does “Who Else” Mean?

Who else means which other person or which additional people.

The word who asks about a person. The word else adds the idea of someone or something additional.

For example:

Who is coming?

This asks you to identify a person or people who are coming.

Who else is coming?

This asks you to identify another person or other people besides those already mentioned, expected, or understood.

That small word else carries an important piece of meaning. It creates a comparison with something already present in the conversation.

Imagine that Sarah says:

“John is coming to the party.”

You might respond:

“Who else is coming?”

You’re not asking whether John is coming. You already know that. You’re asking about additional people.

The same pattern appears in many everyday situations:

• Who else is joining us?
• Who else knows about this?
• Who else wants to go?
• Who else lives here?
• Who else saw what happened?
• Who else needs a ticket?

In each case, else means “in addition to the person or people already known or considered.”

Why “who else” sounds so natural

English speakers use who very freely in questions. Modern English does not always preserve the strict subject-object distinction that traditional grammar associates with who and whom.

Cambridge notes that who can function as either the subject or object of a verb in questions. It gives examples such as “Who did this?” and “Who did you meet?”

That matters because learners sometimes assume that every object must use whom. Actual modern usage is more flexible.

For example:

Who did you invite?

Most American English speakers would find this completely normal.

The more formal version is:

Whom did you invite?

The second sentence isn’t necessarily wrong. It simply belongs to a more formal grammatical style.

The same distinction applies to who else and whom else.

What Does “Whom Else” Mean?

Whom else refers to another person who functions as an object of a verb or preposition.

Traditional grammar treats who as the subject form and whom as the object form. Cambridge explicitly defines whom as the object form of who and says it is used for people as the object of a verb or preposition, particularly in formal styles or writing.

For example:

Whom did you invite?

Here, you act inviting. The person invited receives that action. Under traditional grammar, whom therefore functions as the object.

Add else:

Whom else did you invite?

The meaning is:

Which other person did you invite?

The grammar follows the same basic pattern.

However, modern English often uses who instead:

Who else did you invite?

That version is extremely common and sounds natural in conversation.

This is where grammar books and real-world usage can seem to pull in different directions. Traditional grammar gives you a clear case-based distinction. Modern English, especially spoken American English, often reduces that distinction.

When “whom else” makes sense

You may encounter whom else in writing that deliberately follows formal grammatical conventions.

For example:

Whom else should the committee consult before making its decision?

The construction treats the person being consulted as the object of consult.

You may also see whom after a preposition:

To whom else should the letter be addressed?

This is grammatically formal. In ordinary conversation, most people would be more likely to say:

Who else should the letter be addressed to?

Cambridge describes the version with a preposition before whom as particularly formal and notes that such structures are not normally used in everyday speech.

Who vs. Whom: The Grammar Behind the Choice

The easiest way to understand who else vs. whom else is to understand who vs. whom first.

Think of the two forms this way:

• Who → traditionally used for the subject
• Whom → traditionally used for the object
• Else → adds the meaning of another or additional

The word else doesn’t change whether the pronoun is a subject or object. It simply modifies the question.

Compare:

Who is coming?

and

Who else is coming?

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 doesn’t turn an object into a subject.

This is one of the most useful things to remember. Don’t decide between who and whom based on the word else. Decide based on the grammatical function of the entire pronoun phrase.

Who Else vs. Whom Else: Subject and Object

A subject acts or occupies the main grammatical position in a clause.

An object receives the action or follows a preposition.

Consider:

Who else wants dinner?

The person represented by who else performs the action expressed by wants. That makes who the traditional subject form.

Now consider:

Whom else did you invite?

The person represented by whom else receives the action of inviting. Under traditional grammar, that makes whom the object form.

Here’s the basic pattern:

Grammatical role	Traditional form	Example
Subject	who	Who else called?
Object	whom	Whom else did you call?
Object in modern conversation	who is common	Who else did you call?
Object after a preposition	whom in formal style	To whom else did you speak?
Object after a trailing preposition	who is common	Who else did you speak to?

That last pair is especially useful.

Compare these sentences

Formal:

To whom else did you speak?

Conversational:

Who else did you speak to?

Both communicate the same basic idea. The difference is primarily one of grammatical style and register.

Cambridge gives the same broader pattern for who and whom: whom is favored in formal styles, especially when a preposition comes before it, while who is common when the preposition remains at the end.

Does “Else” Change the Grammar?

No. Else changes the meaning, not the grammatical case.

This distinction is easy to miss.

Suppose you have:

Who called?

Adding else gives:

Who else called?

The phrase still acts as the subject.

Now take:

Whom did you call?

Adding else gives:

Whom else did you call?

The phrase still acts as the object under traditional grammar.

So you can think of else as a meaning word rather than a case-changing word.

What “else” usually adds

Else can mean:

• another person
• another group
• an additional possibility
• something different
• something beyond what has already been mentioned

With who, it usually means another person or other people.

For example:

Who else knows the password?

This assumes that at least one person is already known or considered.

Who else wants to come with us?

This suggests that someone has already agreed or that the speaker expects additional people might join.

Who else should we invite?

This asks for additional names beyond the people already considered.

The word else therefore gives the question context. Without it, who asks for an identity. With it, who else asks for an additional identity.

When Is “Who Else” Correct?

Who else works naturally in a wide range of situations.

When the person is the subject

Use who else when the person acts.

Examples:

• Who else wants to participate?
• Who else knows the truth?
• Who else lives in this building?
• Who else can solve this problem?
• Who else remembers the meeting?

In each example, the unknown person is connected directly to the main verb.

In ordinary questions

You will commonly hear who else in questions about:

• attendance
• knowledge
• responsibility
• preferences
• plans
• opinions
• actions
• membership
• participation

For example: Who else is going to the conference?Who else has seen this report?Who else wants pizza?Who else should we ask?

The last example is particularly interesting because who else functions as the object of ask in traditional grammar. Yet modern English still commonly uses who.

That illustrates an important fact: modern English usage doesn’t always follow the traditional who/whom distinction rigidly. Cambridge explicitly recognizes who as an object in questions.

When Is “Whom Else” Correct?

Whom else can be correct when the pronoun functions as an object under traditional grammar.

Consider:

Whom else did the manager contact?

Traditional analysis identifies the manager as the subject and whom else as the object of contact.

Likewise:

Whom else should we notify?

The pronoun represents the person who would receive the notification.

These sentences are grammatically defensible in formal English. However, they can sound more formal than most people expect.

A modern speaker is much more likely to say:

Who else did the manager contact?

or:

Who else should we notify?

Neither version creates a communication problem. In fact, the who version will often feel more direct and natural.

Formality changes the feel

Compare:

Whom else would you recommend for the position?

with:

Who else would you recommend for the position?

The first has a formal, somewhat traditional tone. The second sounds normal in workplace conversation.

That doesn’t mean whom is useless. It means you should use it because the context calls for it, not merely because it looks sophisticated.

Who Else After a Preposition

Prepositions make who vs. whom especially confusing.

In formal English, a preposition often comes directly before whom:

To whom else should I send the documents?

With whom else did you discuss the matter?

For whom else was the position created?

These constructions follow traditional grammar.

In everyday English, speakers commonly move the preposition to the end and use who: Who else should I send the documents to?Who else did you discuss the matter with?Who else was the position created for?

Cambridge specifically notes this contrast. It describes preposition-plus-whom constructions as more formal and gives less formal alternatives where the preposition appears at the end.

Formal vs. conversational examples

Formal	More natural in conversation
To whom else did you speak?	Who else did you speak to?
With whom else are you traveling?	Who else are you traveling with?
For whom else is this information relevant?	Who else is this information relevant to?
About whom else were you asking?	Who else were you asking about?

If you’re writing a formal legal, academic, or highly polished document, the first column may fit the intended register. For ordinary communication, the second column usually sounds more natural.

A Practical Way to Decide

When you’re unsure, don’t stare at who and whom in isolation. Look at the whole sentence.

Ask yourself:

What is the person doing?

If the person acts, traditional grammar points toward who.

Who else called you?

The unknown person called.

If the person receives the action, traditional grammar points toward whom.

Whom else did you call?

You performed the calling; the unknown person received it.

Then ask a second question:

Would a modern English speaker naturally use whom here?

Often, the answer is no.

That’s why:

Who else did you call?

is perfectly normal modern English even though whom is traditionally associated with object position.

The He/Him Test for “Who Else” and “Whom Else”

The classic he/him test provides a quick traditional grammar check.

Replace the unknown person with he or him.

• If he works, use who.
• If him works, traditional grammar favors whom.

Example:

Who else called?

Replace the unknown person with “he”:

He called.

That works, so who fits.

Now:

Whom else did you call?

Replace the unknown person with “him”:

You called him.

That works, so traditional grammar favors whom.

Another example

Who else can help?

Try:

He can help.

Correct. Therefore:

Who else can help?

Now:

Whom else did she invite?

Try:

She invited him.

Correct. Therefore:

Whom else did she invite?

But remember the important modern-usage point: many speakers would still say:

Who else did she invite?

The he/him test explains the traditional grammar. It doesn’t predict every choice made by modern English speakers.

Why “Who Else” Is More Common in Everyday English

English has changed over time. The distinction between who and whom remains visible in formal grammar, but everyday speech uses who much more broadly.

Cambridge describes whom as formal and says it is much more common in writing than in speaking.

This helps explain why who else feels natural in conversation: Who else is coming?Who else did you tell?Who else should I call?

A speaker doesn’t usually stop to calculate the grammatical case before asking each question. The shorter, familiar form who works smoothly.

That’s especially true when a preposition comes at the end:

Who else are you going with?

A very formal alternative would be:

With whom else are you going?

The second sentence is grammatically polished, but it sounds considerably more formal.

Who Else vs. Whom Else in American English

In American English, who has a very strong position in everyday speech.

You’ll routinely hear:

• Who did you meet?
• Who did you invite?
• Who are you talking to?
• Who else did you call?
• Who else should we ask?

Traditional grammar may recommend whom in several of these sentences. Modern usage, however, commonly favors who.

This doesn’t mean Americans have stopped understanding whom. It still appears in familiar formal expressions such as:

• to whom
• with whom
• for whom
• of whom

It also appears in carefully edited writing.

The key difference is frequency and register, not whether speakers know the word.

Common Mistakes With “Who Else” and “Whom Else”

Using “whom” just to sound formal

A common mistake is assuming that whom automatically makes a sentence better.

It doesn’t.

For example:

Whom else wants to join us?

This is incorrect because whom is being used as the subject of wants.

The correct sentence is:

Who else wants to join us?

Formality cannot override grammatical function.

Assuming “who” is always informal

The opposite mistake also causes problems.

Consider:

The researcher consulted several experts, some of whom had published extensively.

Here, whom fits a formal written structure.

Replacing it with who may be acceptable in less formal English, but the traditional formal construction clearly favors whom.

Confusing the subject and object

Compare:

Who else called the manager?

Here, who else performs the calling.

But:

Whom else did the manager call?

Here, the manager performs the calling.

The two sentences differ only in who acts.

Assuming every preposition requires “whom”

This is another outdated shortcut.

You might learn:

Preposition + person = whom.

That rule works for traditional formal grammar, but modern English often moves the preposition to the end:

Who else did you talk to?

Cambridge recognizes this modern structure and contrasts it with more formal to whom constructions.

Overcorrecting your writing

Trying too hard to sound formal can make otherwise clear writing feel unnatural.

For example:

To whom else might I direct this inquiry?

This may be perfectly appropriate in a formal letter.

But in an everyday email, you might simply write:

Who else should I contact?

Good writing isn’t about choosing the most formal word available. It’s about choosing the word that fits the meaning, grammar, audience, and context.

Who Else vs. Whom Else: Side-by-Side Examples

Sentence	Traditional grammar	Modern natural usage	Why
Who else is coming?	Correct	Natural	Who is the subject
Who else knows?	Correct	Natural	Who is the subject
Whom else did you invite?	Correct	Formal	Who is the object
Who else did you invite?	Common modern usage	Very natural	Who is used as an object
To whom else did you speak?	Correct	Very formal	Whom follows a preposition
Who else did you speak to?	Modern usage	Natural	Preposition moves to the end
Who else should we ask?	Common modern usage	Natural	Who is used as an object
Whom else should we ask?	Traditional/formal	Formal	Object form

The table shows why a simple “who equals subject, whom equals object” rule isn’t enough for modern English.

Examples of “Who Else” in Everyday English

These sound professional without sounding overly formal.

In the classroom Who else knows the answer?Who else finished the assignment?Who else wants to present first?

Teachers and students use this pattern naturally because it quickly asks about additional people.

In conversation Who else is coming tonight?Who else did you tell?Who else wants dessert?Who else saw that?

These are ordinary examples where who else feels much more natural than whom else.

In email

You might write:

Who else should I include on the email?

or:

Who else needs this information?

Even in professional correspondence, there is usually no advantage in replacing natural who with unnecessarily formal whom.

Examples of “Whom Else” in Formal English

Although whom else is less common, it isn’t meaningless or automatically incorrect.

Consider:

Whom else should the board consult before approving the proposal?

The construction treats the unknown person as the object of consultation.

Another example:

Whom else did the committee interview?

Traditional grammar recognizes whom as the object.

A particularly formal construction is:

With whom else did the director discuss the matter?

Here, whom follows the preposition with.

The everyday alternative would be:

Who else did the director discuss the matter with?

Both communicate essentially the same idea. The difference lies in register and grammatical tradition.

What Should You Use in Formal Writing?

The answer depends on the type of formal writing.

For highly traditional or carefully edited prose, whom can be appropriate when it clearly functions as an object.

Examples include:

To whom else should the application be submitted?

The candidates, several of whom had extensive experience, were interviewed.

For general professional writing, clarity usually matters more than forcing formal pronouns into every sentence.

A business email that says:

Who else should I contact?

doesn’t look careless. It looks clear and natural.

The goal should be appropriate formality, not maximum formality.

A Useful “Who Else” Case Study

Imagine a manager writing to a colleague:

Who else should I invite to the meeting?

This sounds direct and professional.

Now change it to:

Whom else should I invite to the meeting?

Traditional grammar can support the second version because the unknown person is the object of invite. Yet the sentence feels more formal.

Now imagine the manager writes:

Whom else should attend the meeting?

That changes the grammar entirely. Here, whom is being used as the subject of should attend, so traditional grammar would favor:

Who else should attend the meeting?

This small change demonstrates why you can’t choose whom simply because the situation is formal.

Grammar follows function.

A Fast Decision Guide

When you encounter who else or whom else, work through this short process:

1. Identify the main verb.
2. Ask who acts.
3. Ask who receives the action.
4. Try the he/him test if you’re following traditional grammar.
5. Check whether a preposition comes directly before the pronoun.
6. Consider whether your writing is formal or conversational.
7. If you’re speaking naturally, who else will often be the best choice.

Quick examples

Who else laughed?

→ He laughed.

Use who.

Whom else did you invite?

→ You invited him.

Traditional grammar favors whom.

Who else did you invite?

→ Common modern English.

Use who comfortably in ordinary American conversation and writing.

To whom else did you speak?

→ Formal.

Who else did you speak to?

→ Conversational and natural.

The Bottom Line on “Who Else” vs. “Whom Else”

The most useful answer is straightforward: use “who else” in most modern English situations.

It’s the natural form for questions such as:

• Who else is coming?
• Who else wants to help?
• Who else knows?
• Who else should we invite?
• Who else did you tell?

Use whom else when you’re deliberately following traditional formal grammar and whom functions as an object.

For example:

Whom else did you invite?

And when a preposition comes directly before the pronoun, formal English may use:

To whom else did you speak?

But ordinary American English usually prefers:

Who else did you speak to?

The biggest mistake is treating whom as a synonym for “more correct.” It isn’t. Who and whom have different grammatical histories and roles, while modern usage has made who acceptable in many places where traditional grammar once demanded whom. Cambridge’s current grammar guidance reflects that distinction, describing whom as formal and noting that who is used both as a subject and object in many questions.

If you’re writing for a general American audience, prioritize clarity and natural usage. In most cases, “who else” gets the job done without sounding stiff. When the context calls for traditional formal grammar, especially with a preposition before the pronoun, “whom else” can still be the right choice.

Who vs. Whom: Understanding the Grammar

The difference between who and whom comes down to one basic idea: who traditionally works as a subject, while whom works as an object. Once that distinction is clear, phrases such as who else and whom else become much easier to analyze. Cambridge Dictionary identifies whom as the object form of who and notes that it appears mainly in formal styles and writing. It also recognizes that who can be used as an object in questions, which reflects normal modern English usage.

What Is “Who”?

Who is a pronoun used when you’re asking about a person or identifying a person. In traditional grammar, it serves as the subject of a verb.

Consider:

Who called you?

The answer might be:

Sarah called me.

Sarah acts calling. Therefore, the unknown person occupies the subject position, making who the traditional choice.

The same pattern appears in:

• Who wants to leave?
• Who knows the answer?
• Who opened the door?
• Who else is coming?
• Who can help us?

In each sentence, the person represented by who performs or controls the action expressed by the verb.

That’s why who else works naturally in a question such as:

Who else wants to join us?

The person you’re asking about is the one who wants to join.

What Is “Whom”?

Whom is traditionally the object form of who. It identifies a person who receives an action or follows a preposition. Cambridge and Merriam-Webster both describe this objective function, while also noting that whom has a distinctly formal feel today.

For example:

Whom did you invite?

The underlying statement is:

You invited him.

You act. He receives it. Because him is an object pronoun, traditional grammar uses whom in the corresponding question.

The same principle gives us:

Whom else did you invite?

The meaning is simply:

Which other person did you invite?

The grammar explains the traditional form. Modern usage explains why many speakers would instead say:

Who else did you invite?

Both points matter. A good explanation shouldn’t pretend that modern English still follows the old distinction in every situation.

Subject Pronouns

A subject normally pacts asthe verb or occupies the grammatical subject position.

Compare:

She called the manager.

She acts.

They organized the event.

They act.

He answered the question.

He acts.

The corresponding traditional question forms are: Who called the manager?Who organized the event?Who answered the question?

The he/she/they replacement works because those pronouns are subject forms.

Subject examples with “who else”

This becomes especially useful when else appears: Who else called the manager?Who else organized the event?Who else answered the question?Who else wants to participate?

The word else doesn’t change the grammatical role of who. It simply means another person or additional people.

For example:

Who called?

asks for the identity of a caller.

Who else called?

Asks for the identity of an additional caller.

That distinction is semantic rather than grammatical.

Object Pronouns

An object receives the action of a verb or completes the meaning of a preposition.

Look at these examples:

I called him.

She invited them.

We consulted her.

They contacted him.

The words him, them, and her don’t perform the actions. They receive them.

Traditional English therefore uses whom in corresponding questions: Whom did you call?Whom did she invite?Whom did we consult?Whom did they contact?

Add else, and the structure becomes: Whom else did you call?Whom else did she invite?Whom else should we consult?

Again, these are grammatically defensible under the traditional subject-object distinction.

However, modern English frequently uses who in these object questions. Merriam-Webster specifically notes that who is widely used as an object and that whom can sound stiff or unnatural in ordinary speech and writing.

The Subject-Object Difference at a Glance

Role	Traditional pronoun	Example	Replacement test
Subject	who	Who called?	He called.
Subject	who	Who else came?	She came.
Object	whom	Whom did you call?	You called him.
Object	whom	Whom else did you invite?	You invited her.
Object in modern usage	who is common	Who did you call?	You called him.

The final row is important. It shows the gap between traditional grammar and actual contemporary usage.

If you learned that who = subject and whom = object, you learned a useful grammatical distinction. But you shouldn’t assume that modern speakers always preserve it.

The He/Him Test

The he/him test is one of the quickest traditional methods for deciding between who and whom.

Replace the unknown person with he or him.

If he fits, choose who.

If him fits, traditional grammar favors whom.

Example: “Who else called?”

Start with:

Who else called?

Turn it into a statement:

He called.

He works. Therefore, who is the traditional choice.

Example: “Whom else did you call?”

Now consider:

Whom else did you call?

Turn it into a statement:

You called him.

Him works. Therefore, traditional grammar favors whom.

This test is simple because English already shows the subject-object distinction clearly in pairs such as:

• he/him
• she/her
• they/them
• we/us
• I/me

The problem is that who and whom are not used with the same consistency in modern English.

The They/Them Test

The they/them test works the same way and can be useful when the person you’re discussing isn’t identified by gender.

Consider:

Who else submitted the application?

Replace the unknown person:

They submitted the application.

That works, so who fits the traditional subject pattern.

Now:

Whom else did the committee select?

Replace the unknown person:

The committee selected them.

That indicates an object, so traditional grammar favors whom.

This method is useful because they/them makes the grammatical relationship easy to see without forcing you to think about a specific person’s gender.

Why “Whom” Still Exists

It can be tempting to think that whom is simply an old-fashioned version of who. That’s not quite right.

Whom has a specific grammatical history. It represents the objective case of who. Merriam-Webster traces its history back to Old English and identifies it as the objective form of who.

English once marked grammatical relationships more extensively through word forms. Over time, many of those distinctions disappeared.

You can see remnants of this system in ordinary pronouns today:

Subject	Object
I	me
he	him
she	her
we	us
they	them
who	whom

Notice something interesting: most modern speakers instinctively know the difference between he and him.

Nobody normally says:

“Me called the office.”

We naturally say:

“I called the office.”

Likewise:

“The manager called me.”

The subject-object distinction remains strong in these pronoun pairs.

Who and whom are different because English speakers have increasingly blurred their distinction in everyday usage.

Why Modern English Uses “Who” More Broadly

Modern English values straightforward, familiar constructions. Whom remains available, but it has become much less common in everyday speech.

Cambridge says whom is used in formal styles or writing and is much more common in writing than speaking. Merriam-Webster similarly describes it as having a formal feel and notes that who is standard in many contexts where traditional grammar might prefer whom.

That explains a sentence such as:

Who did you speak to?

Most people find it completely natural.

The traditional alternative is:

To whom did you speak?

The second version isn’t necessarily better. It’s simply more formal.

The same contrast applies to who else:

Who else did you speak to?

versus:

To whom else did you speak?

The first sounds like normal conversation. The second sounds more formal and deliberate.

Who Can Be an Object?

This is one of the most important facts for understanding modern English.

Traditional grammar says that an object should use whom. Yet modern English regularly uses who as an object.

Cambridge gives “Who did you talk to?” as a normal question and explicitly describes whom as the formal object form.

Merriam-Webster goes further by explaining that reputable writers and speakers use who as an object of a verb or following a preposition.

So these sentences are both found in English: Whom did you meet?Who did you meet?

The first follows the traditional objective form.

The second follows common modern usage.

The practical lesson is important:

Traditional correctness and modern naturalness aren’t always identical.

That doesn’t mean grammar rules are useless. It means you need to understand the rule and also understand how English speakers actually use the language.

Why “Who Else Did You Invite?” Sounds Natural

Now apply everything to the target phrase.

Traditional analysis:

Whom else did you invite?

The person being invited is the object.

Modern English:

Who else did you invite?

The second sentence sounds more natural to most American English speakers.

Why?

Because who has expanded beyond its traditional subject-only role. It now commonly appears in object questions, particularly in everyday speech.

This is not a random mistake. It is an established usage pattern documented by major dictionaries and grammar references. Merriam-Webster specifically says that who is standard in many contexts where whom may be technically correct but sound awkward.

Prepositions Make the Difference More Noticeable

The traditional distinction becomes clearer when a preposition appears.

Consider:

With whom did you travel?

Traditional formal grammar strongly favors whom after with.

But ordinary English commonly says:

Who did you travel with?

Both sentences are understandable and grammatical within their respective usage patterns.

Cambridge describes this difference directly: whom is commonly used with prepositions in formal styles, while everyday English often places the preposition at the end and uses who.

The same principle applies to who else:

With whom else did you travel?

Formal.

Who else did you travel with?

Natural and conversational.

Neither sentence changes the underlying meaning.

A Useful Mental Model

Think of who and whom as two layers of English.

The first layer is traditional grammar:

• who → subject
• whom → object

The second layer is modern usage:

• who → subject
• who → often used as object
• whom → mainly retained in formal constructions, especially after prepositions

That model explains most of the confusion without requiring dozens of isolated rules.

Traditional layer

Who called?

Whom did you call?

Modern layer

Who called?

Who did you call?

Formal preposition construction

To whom did you speak?

Natural conversational construction

Who did you speak to?

Once you see these as different registers rather than competing “right versus wrong” sentences, the subject becomes much easier.

Does “Else” Affect Subject or Object Status?

No.

This point deserves emphasis because else appears directly beside the pronoun.

Compare:

Who else called?

and:

Whom else did you call?

The word else simply means another or additional.

It doesn’t determine the case.

You can remove it:

Who called?

Whom did you call?

The grammatical relationship stays the same.

You can put it back:

Who else called?

Whom else did you call?

The relationship remains unchanged.

So if you’re trying to decide between who else and whom else, don’t ask:

“Does else require who or whom?”

Instead ask:

“What grammatical role does the entire phrase play?”

That’s the more reliable question.

Who, Whom, and Prepositions

Prepositions introduce another layer because they create object relationships.

Common prepositions include:

• to
• with
• for
• from
• about
• by
• of

Traditional formal English often places whom directly after these words.

Examples:

To whom did you send the letter?

With whom did you speak?

For whom was the package intended?

About whom were they talking?

Of whom are you speaking?

Modern English often shifts the preposition to the end: Who did you send the letter toWho did you speak with?Who was the package intended for?Who were they talking about?Who are you speaking of?

The first set sounds more formal. The second set sounds more conversational.

Cambridge’s guidance supports this distinction and gives formal preposition + whom constructions alongside less formal alternatives with the preposition at the end.

Who vs. Whom in Relative Clauses

The same subject-object distinction appears outside questions.

Consider:

The woman who called me is a doctor.

Here, who is the subject of called.

Now:

The woman whom I called is a doctor.

Here, I is the subject of called, while whom is the object.

Traditional grammar therefore distinguishes:

The woman who called me…

from:

The woman whom I called…

However, modern English often uses who in the second sentence too:

The woman who I called is a doctor.

Cambridge specifically notes that who can function as the subject or object of a relative clause, while whom is associated with formal writing when it serves as the object.

This broader pattern reinforces the main lesson: English speakers increasingly rely on who in places where older grammatical rules preferred whom.

Why Context Matters

Grammar doesn’t operate separately from audience and purpose.

Imagine three situations.

A casual conversation

Who else are you inviting?

This sounds completely natural.

A professional email

Who else should I include in the discussion?

Again, natural and professional.

A highly formal document

To whom else should the notice be directed?

Here, the formal construction may be appropriate.

The best choice isn’t necessarily the most traditional one. It is the one that fits the context, audience, and level of formality.

A Quick Comparison

Feature	Who	Whom
Traditional role	Subject	Object
Modern object use	Very common	Less common
Everyday speech	Very common	Rare
Formal writing	Common	More common
After a preposition	Common when preposition moves to end	Preferred in formal style
Natural in “Who else?”	Yes	No
Natural in “Whom else?”	—	Formal/object construction

The Most Useful Rule to Remember

If you’re learning the traditional distinction, remember:

Who does. Whom receives.

For example:

Who else called?

The person did the calling.

Whom else did you call?

The person received the call.

Then add the modern-English rule:

Who is widely used for objects in everyday English.

That gives you a much more accurate picture than memorizing “who is always subject and whom is always object.”

The practical takeaway

When you need a natural American English sentence, who will usually be your best choice.

When you’re writing in a deliberately formal style, whom remains useful when it functions as an object, particularly after a preposition.

And when you’re checking a traditional grammar exercise, the he/him or they/them test can quickly reveal which form the exercise expects.

Understanding both systems gives you something more valuable than a single rule: control over your language. You can recognize why “Whom else did you invite?” is traditionally defensible while also understanding why “Who else did you invite?” is the more natural choice for most modern American readers and speakers.

When to Use “Who Else” and “Whom Else”

The easiest way to choose between “who else” and “whom else” is to look at the phrase’s role in the sentence. In traditional grammar, who acts as a subject and whom acts as an object. Modern English, however, uses who much more freely, including in many object positions. That is why “Who else did you invite?” sounds completely natural even though traditional grammar would favor “Whom else did you invite?”. For most readers and speakers of modern American English, who else is the practical default. Whom else remains useful when you deliberately follow formal grammatical conventions, especially after a preposition.

When to Use “Who Else”

Use who else when you’re asking about another person or group of people and the phrase works naturally as a subject.

For example:

Who else is coming to dinner?

Here, who else is the subject of is coming. The unknown people act as the subject of coming.

Other natural examples include:

• Who else wants to join us?
• Who else knows the answer?
• Who else can help with this project?
• Who else lives in this neighborhood?
• Who else remembers what happened?
• Who else has finished the assignment?

The pattern is straightforward:

Who else + verb

Examples: Who else wants coffee?Who else needs help?Who else has seen the report?Who else can attend?

In each case, the person represented by who else connects directly to the verb as its subject.

But that’s not the only reason modern English uses who else. Speakers also commonly use who as an object.

Consider:

Who else did you invite?

Traditional grammar would analyze who else as the object of invite and recommend whom else. Yet modern American English overwhelmingly favors the first version in ordinary conversation.

So don’t assume that who else is limited to subject positions in real-world English. Modern usage is broader than the traditional rule.

When “Who Else” Is the Natural Choice

In everyday American English, who else is usually the best choice when you want to sound clear and natural.

It works particularly well in questions about:

• People attending an event
• People involved in a task
• People who know something
• People who want something
• People who can help
• People who have taken an action
• People who should be contacted
• People who might participate

For example: Who else should we invite to the meeting?Who else did you tell about the change?Who else has access to the account?Who else would be interested in this opportunity?

These questions don’t sound careless or grammatically weak. They’re standard, efficient English.

When to Use “Whom Else”

Use whom else when you are following traditional formal grammar and the pronoun functions as an object.

For example:

Whom else did the committee interview?

Traditional grammar identifies the committee as the subject and whom else as the object of interview.

Another example:

Whom else should the board consult?

The board performs the action of consulting. The unknown person receives that action.

You can test the structure:

The board should consult him.

Because him works, traditional grammar selects whom.

This gives you:

Whom else should the board consult?

However, most people in everyday American English would probably say:

Who else should the board consult?

That’s why context matters. Whom else isn’t automatically wrong, but it can sound noticeably formal.

“Whom Else” After a Preposition

The strongest case for whom occurs when a preposition comes directly before the pronoun.

Examples include:

To whom else should I send the documents?

With whom else did you discuss the proposal?

For whom else was the position created?

About whom else were they asking?

Traditional formal grammar strongly supports these constructions because whom functions as the object of the preposition.

In everyday American English, speakers commonly move the preposition to the end: Who else should I send the documents to?Who else did you discuss the proposal with?Who else was the position created for?Who else were they asking about?

The difference is mainly register, meaning the level or style of language appropriate to a particular situation.

Formal construction	Everyday construction
To whom else should I speak?	Who else should I speak to?
With whom else did you travel?	Who else did you travel with?
For whom else is this intended?	Who else is this intended for?
About whom else did she ask?	Who else did she ask about?

Cambridge notes that whom is especially associated with formal writing and that modern English commonly uses who when a preposition is placed at the end of a question.

How the He/Him Test Helps

The he/him test remains one of the fastest ways to understand the traditional distinction.

Replace who or whom with he or him.

If he works, traditional grammar favors who.

If him works, traditional grammar favors whom.

Example: “Who else called?”

Replace the unknown person:

He called.

Because he works, who is correct under the traditional rule.

Example: “Whom else did you call?”

Replace the unknown person:

You called him.

Because him works, traditional grammar favors whom.

Example: “Who else should attend?”

Try:

He should attend.

That works.

Therefore:

Who else should attend?

Example: “Whom else should we contact?”

Try:

We should contact him.

That works.

Traditional grammar therefore gives:

Whom else should we contact?

But modern English commonly says:

Who else should we contact?

This is the point where learners sometimes get frustrated. The grammar test gives you whom, while normal usage gives you who.

Both facts can be true at the same time.

The He/Him Test Is a Guide, Not a Complete Modern-English Rule

The he/him test is useful for understanding grammatical structure. It isn’t a command that every English speaker follows.

For example:

Who did you meet?

Traditional analysis:

You met him.

Therefore, traditional grammar would favor whom.

Yet:

Who did you meet?

is entirely normal modern English.

That means the test tells you why “whom” is traditionally possible. It doesn’t mean that “who” is automatically incorrect in modern usage.

The same applies to:

Who else did you invite?

The traditional object analysis supports whom else, but modern usage strongly supports who else.

Subject vs. Object: A Clear Comparison

Question	Traditional analysis	Modern natural choice
Who else called?	Who = subject	Who else called?
Who else is coming?	Who = subject	Who else is coming?
Whom else did you invite?	Whom = object	Who else did you invite?
Whom else should we ask?	Whom = object	Who else should we ask?
To whom else did you speak?	Whom = object of preposition	Who else did you speak to?
With whom else are you going?	Whom = object of preposition	Who else are you going with?

This table captures the practical distinction better than a simple “who = subject, whom = object” rule.

When “Whom Else” Sounds Better

There are situations where whom else can be the better stylistic choice.

Formal legal writing

Legal writing often preserves traditional constructions involving whom.

For example:

To whom else was the notice delivered?

The formal construction fits the register.

Highly formal correspondence

A very formal letter might say:

To whom else should the application be directed?

This sounds deliberate and polished.

In an ordinary email, however:

Who else should I send the application to?

is usually clearer and less stiff.

Academic writing

Academic writing can use whom when the grammatical structure calls for it:

The researchers identified the participants, several of whom had previously completed the survey.

However, there’s no reason to insert whom simply to make academic writing sound intelligent.

Good academic prose values precision, not unnecessary formality.

When “Who Else” Works Better

For most readers, who else works better in:

Everyday conversation

Who else is coming?

Workplace communication

Who else needs the report?

Customer communication

Who else should we contact?

Informal writing

Who else wants to join?

General web content

Who else can benefit from this approach?

The phrase is short, familiar, and easy to process.

If the audience is broad, who else generally creates less friction.

“Who Else” in Questions About People

One of the most common uses of who else is to ask about additional people.

Suppose three people have already agreed to attend an event. Someone asks:

Who else is coming?

The word else signals that the speaker already knows about some attendees.

The same idea appears in: Who else knows about the plan?Who else received the invitation?Who else wants to participate?Who else has applied?

In each case, else creates a relationship with information already established or assumed.

Without else, the question is broader:

Who is coming?

With else, the speaker asks:

Which additional person or people are coming?

That small difference makes else an important semantic part of the phrase.

“Who Else” Does Not Always Mean “Another Person”

The meaning depends on context.

For example:

Who else could solve this problem?

This may mean:

Which other person could solve it?

But it could also imply:

Is there anyone besides the person already being considered who could solve it?

Similarly:

Who else should we ask?

Could refer to additional people who might have useful information.

The phrase therefore doesn’t necessarily require that someone has already been explicitly named. The context can establish the comparison.

For example:

“This issue is difficult. Who else could help us?”

Nobody may have been named. Still, else means “apart from the people or possibilities already under consideration.”

“Whom Else” Does Not Automatically Sound Wrong

It’s important not to turn the lesson into another oversimplified rule.

Whom else is a legitimate construction.

Consider:

Whom else could the committee have selected?

Traditional grammar supports whom because the person is the object of selected.

The issue is not that whom else is inherently ungrammatical. The issue is that modern speakers often prefer who else in the same position.

So these two statements can both be accurate:

• “Whom else did you invite?” follows traditional object-case grammar.
• “Who else did you invite?” is more natural in modern American English.

That distinction is essential if you’re trying to understand actual English rather than memorize isolated rules.

Which Form Should You Choose?

Use this practical decision guide.

Situation	Recommended form
Casual conversation	Who else
General American English	Who else
Everyday questions	Who else
Professional email	Usually who else
General website content	Usually who else
Formal writing with an object	Whom else can be appropriate
Preposition + pronoun in formal writing	Whom else
Preposition at the end in conversation	Who else
Traditional grammar exercise	Follow the subject/object rule

A simple three-question check

When you’re unsure, ask:

Is the phrase the subject?

Use who else.

Is the phrase an object, and am I deliberately following formal traditional grammar?

Use whom else.

Is this ordinary modern American English?

Who else will usually be the better choice.

Common Sentences and Their Best Forms

Natural modern English

• Who else is coming?
• Who else wants to go?
• Who else knows?
• Who else did you invite?
• Who else should we contact?
• Who else can help?
• Who else did you speak to?

Formal traditional English

• Whom else did you invite?
• Whom else should we contact?
• To whom else did you speak?
• With whom else did you travel?
• For whom else was the position intended?

Notice that the formal examples aren’t necessarily “better.” They simply use a more traditional grammatical pattern.

A Practical Workplace Example

Imagine a project manager preparing a meeting.

The manager could write:

Who else should we invite to the meeting?

This is natural, concise, and professional.

A highly formal version would be:

Whom else should we invite to the meeting?

Traditional grammar supports it. Yet most modern American readers won’t consider the first version less professional.

Now change the structure:

Who else should attend the meeting?

Here, who else is clearly the subject of should attend.

That makes the choice especially straightforward.

If you accidentally wrote:

Whom else should attend the meeting?

the problem isn’t merely that the sentence sounds formal. Under traditional grammar, whom occupies the subject position and therefore doesn’t fit the expected case.

The correct form is:

Who else should attend the meeting?

A Practical Writing Example

Suppose you’re writing a formal report:

The committee interviewed five candidates, several of whom had previous management experience.

Here, whom fits naturally because it follows several of and refers to the people who were interviewed.

But if you’re asking a direct question:

Who else did the committee interview?

Modern English strongly favors who.

This illustrates an important difference between fixed formal constructions and ordinary questions.

The Best Rule for Modern American English

If you’re writing for a broad American audience, don’t force yourself to use whom every time traditional grammar identifies an object.

Instead:

• Use who naturally in everyday questions.
• Use whom when the formal construction clearly calls for it.
• Keep whom after a preposition when you’re deliberately using formal English.
• Don’t use whom merely to make a sentence sound smarter.
• Don’t assume who is incorrect simply because the pronoun functions as an object.
• Consider your audience and the tone of the writing.

This approach gives you both grammatical awareness and natural fluency.

Quick Reference: Who Else or Whom Else?

Who else = the normal modern choice in most situations.

Whom else = the traditional formal object form.

Who else did you invite? = natural modern American English.

Whom else did you invite? = traditional and formal.

Who else did you speak to? = natural modern English.

To whom else did you speak? = formal English.

The safest choice for ordinary communication is simple: use “who else” unless your sentence or writing style specifically calls for formal “whom.”

Understanding that distinction helps you avoid two opposite mistakes. You won’t incorrectly assume that whom is always more correct, and you won’t mistakenly assume that who can never function as an object. Modern English is more flexible than that.

Who Else vs. Whom Else in Everyday English

When people ask “Who else?” or “Whom else?”, the choice depends on grammar, formality, and modern usage. In traditional grammar, who is the subject form and whom is the object form. Yet everyday American English usually favors who, even when the pronoun functions as an object. That’s why “Who else did you invite?” sounds natural to most speakers, while “Whom else did you invite?” sounds formal or old-fashioned. The difference becomes much easier when you look at the sentence around the pronoun rather than treating who, whom, and else as separate rules.

Examples of “Who Else” in Everyday English

The phrase who else appears constantly in ordinary questions because it lets you ask about an additional person or group without sounding formal.

For example:

Who else is coming to the party?

Here, who else is the subject of is coming.

You can use the same structure in many everyday situations:

• Who else wants pizza?
• Who else knows about the meeting?
• Who else can help us?
• Who else lives here?
• Who else has seen this movie?
• Who else wants to come along?
• Who else needs a copy?

The word else means another person or additional people in the context. If you’ve already discussed Sarah and John, asking “Who else is coming?” means you’re asking about anyone beyond Sarah and John.

Questions

Questions are probably where you’ll encounter who else most often. Who else is joining us?Who else wants to volunteer?Who else knows the password?Who else saw what happened?Who else should we invite?

The last example is especially interesting. Under traditional grammar, who is technically the object of invite, so whom could be used:

Whom else should we invite?

However, “Who else should we invite?” is much more natural in contemporary American English.

That’s a good example of the difference between a traditional grammatical rule and actual modern usage.

Everyday Conversations

In conversation, who else rarely creates confusion.

Imagine two friends planning dinner:

“I’m inviting Maya and Daniel.”

“Who else are you inviting?”

The phrase feels effortless because speakers don’t normally stop to analyze grammatical case during casual conversation.

You might also hear:“Who else was there?”“Who else did you tell?”“Who else wants to go?”“Who else have you asked?”

These examples show why who else has become so common. It works smoothly across both subject and object constructions.

Workplace Examples

Professional communication doesn’t require whom simply because the setting is formal.

For example: Who else should receive this report?Who else needs access to the document?Who else attended the meeting?Who else should we contact before Friday?

These sentences are professional, direct, and easy to understand.

Using whom isn’t automatically more polished:

Whom else should we contact before Friday?

This is grammatically defensible under traditional rules, but it can sound unnecessarily stiff in an ordinary workplace message.

A useful principle is clarity before ceremony. Formal language should serve the reader rather than merely display grammatical knowledge.

Classroom Examples

Teachers and students use who else in questions about participation, answers, and classroom activities.

Examples include: Who else knows the answer? Who else finished the assignment?Who else wants to present first?Who else has a question?Who else read the assigned chapter?

In these sentences, who else makes the question sound natural and approachable.

A teacher asking:

Who else would like to answer?

sounds completely normal.

There is no practical benefit in replacing it with:

Whom else would like to answer?

That version is not correct because the pronoun is functioning as the subject of would like.

Email Examples

In emails, who else works well in both casual and professional communication.

For example: Who else should I include on this email?Who else needs the updated schedule?Who else will be attending the presentation?Who else should receive a copy of the contract?

These sentences are clear without being overly formal.

If the email has a highly formal tone, you might encounter:

To whom else should the correspondence be sent?

That construction follows traditional formal grammar.

Still, a simpler version is often easier to read:

Who else should I send the correspondence to?

The choice depends on the audience and the desired tone.

Common Expressions With “Who Else”

Some expressions naturally contain who else because the phrase has become deeply established in everyday English.

Examples include:

• Who else?
• Who else knows?
• Who else wants to go?
• Who else could it be?
• Who else would know?
• Who else can help?
• Who else is involved?
• Who else is coming?

Consider the short question:

Who else?

It can mean:

“Who is another person involved?”

The surrounding conversation supplies the missing context.

For instance:

“We’ve already asked Maria.”

“Who else?”

The speaker is asking which additional person should be considered.

Usage Tip

Don’t automatically replace who with whom just because the sentence sounds formal.

A common mistake is to treat whom as the “fancier” or “more educated” version of who. That’s not how the distinction works.

Whom has a grammatical function. It traditionally marks the objective case.

For example:

Whom did you call?

The answer might be:

“I called him.”

But modern English commonly says:

Who did you call?

The same pattern applies to else:

Who else did you call?

is the natural modern version.

A good writer chooses whom when it adds grammatical or stylistic value, not simply because it sounds formal.

Examples of “Whom Else” in Formal English

Whom else is legitimate when traditional grammar calls for an object pronoun. It appears most naturally in formal writing, especially when the sentence already has a formal structure.

For example:

Whom else did the committee consider for the position?

The committee is the subject. The person considered is the object.

Another example:

Whom else should the organization consult before making its decision?

The organization acts. The people consulted receive that action.

In everyday American English, however, most people would say:

Who else should the organization consult before making its decision?

That version is more conversational without changing the meaning.

After Prepositions

Whom is particularly common after prepositions in formal English.

Examples include:

To whom else should the letter be addressed?

With whom else did the researcher speak?

For whom else was the position created?

About whom else did the witness provide information?

By whom else was the decision approved?

Traditional grammar favors whom because the pronoun serves as the object of the preposition.

In everyday English, speakers often move the preposition to the end: Who else should the letter be addressed to?Who else did the researcher speak with?Who else was the position created for?

Who else did the witness provide information about?Who else approved the decision?

The final example changes the sentence structure slightly, but it demonstrates how easily modern English can avoid the formal whom construction.

Formal vs. Everyday English

The difference between who else and whom else is often a difference in register rather than meaning.

Everyday English	Formal English
Who else did you ask?	Whom else did you ask?
Who else did you speak with?	With whom else did you speak?
Who else should I contact?	Whom else should I contact?
Who else should I send this to?	To whom else should I send this?
Who else are you working with?	With whom else are you working?

The formal versions are not automatically better. They simply preserve the traditional distinction more carefully.

For most general readers, the everyday versions usually feel more direct.

Business and Legal Writing

Business and legal writing sometimes preserves whom, particularly in established formal constructions.

For example:

To whom else should the notice be delivered?

With whom else did the parties communicate?

For whom else was the agreement prepared?

Such constructions can fit a deliberately formal document.

However, formal writing should not become difficult merely to sound authoritative. If a straightforward sentence communicates the same information, it may be the stronger choice:

Who else should receive the notice?

The goal is not to eliminate whom. The goal is to use it where it fits naturally.

Academic Writing

Academic writing may use whom when traditional grammar or sentence structure calls for it.

For example:

The study identified several participants, some of whom had previously worked in the field.

Here, whom is part of the formal relative-pronoun construction some of whom.

Another example:

The researchers determined whom else they needed to interview.

The grammatical structure is more complex here because whom else occurs inside a clause.

In less formal prose, writers may use who instead:

The researchers determined who else they needed to interview.

That version is common in modern English and is often easier for general readers.

Traditional Grammar Examples

Traditional grammar gives a clear framework:

Who called you?

He called me.

Therefore, who.

Whom did you call?

I called him.

Therefore, whom.

Now add else:

Who else called you?

He called you.

Whom else did you call?

You called him.

This is the traditional logic.

The difficulty begins because modern English often replaces the second construction:

Who else did you call?

That doesn’t mean the old rule has disappeared from every formal context. It means English has developed broader everyday usage.

Editorial Tip

When editing general-audience American English, who else is usually the safest choice unless the sentence requires a deliberately formal construction.

Don’t change every who into whom simply because the pronoun follows a verb.

Instead, ask:

1. What role does the pronoun play?
2. Is the writing formal or conversational?
3. Does whom make the sentence clearer?
4. Would the average reader naturally expect who?
5. Is a preposition directly before the pronoun?

This approach prevents both underuse and overuse.

Who Else vs. Whom Else: Side-by-Side Comparison

Example	Traditional grammar	Modern American English
Who else is coming?	Correct	Correct
Who else wants coffee?	Correct	Correct
Who else called you?	Correct	Correct
Who else did you call?	Traditionally whom	Who is natural
Whom else did you call?	Correct	Formal
Who else should we invite?	Modern usage	Natural
Whom else should we invite?	Traditional object form	Formal
To whom else did you speak?	Formal and traditional	Formal
Who else did you speak to?	Modern usage	Natural
With whom else did you work?	Formal	Formal
Who else did you work with?	Modern usage	Natural

The key difference isn’t meaning. Both forms can ask about the same person or people.

The difference lies mainly in grammatical tradition, register, and modern usage.

Easy Grammar Tricks to Remember

The fastest way to understand the distinction is to use a few simple substitution tests.

The He/Him Test

Replace the unknown person with he or him.

Who else came?

Try:

He came.

Correct.

Therefore:

Who else came?

Now:

Whom else did you invite?

Try:

You invited him.

That supports whom under traditional grammar.

The They/Them Test

Use they and them when you don’t want to assign gender.

Who else arrived?

→ They arrived.

So traditional grammar favors who.

Whom else did you contact?

→ You contacted them.

So traditional grammar favors whom.

The Quick Replacement Method

You can make the test even shorter:

Who → he/they

Whom → him/them

For example:

Who else should attend?

→ They should attend.

Use who.

Whom else should we invite?

→ We should invite them.

Traditional grammar favors whom.

This method won’t tell you which form modern speakers are most likely to choose, but it quickly reveals the underlying grammatical structure.

Quick Memory Checklist

Keep these points in mind:

• Who is traditionally the subject form.
• Whom is traditionally the object form.
• Else means another or additional.
• Else doesn’t determine whether you use who or whom.
• Who else is extremely common in modern English.
• Whom else remains valid in formal traditional usage.
• Who else did you invite? is natural modern English.
• Whom else did you invite? is more formal.
• To whom else did you speak? is a traditional formal construction.
• Who else did you speak to? is the natural conversational alternative.
• The he/him test helps identify traditional case.
• The they/them test works in the same way.
• Don’t use whom merely to sound sophisticated.
• Choose the form that fits the audience and context.

Why Native Speakers Usually Say “Who Else”

Native speakers generally don’t pause during ordinary conversation to identify whether a pronoun is functioning as a direct object.

They tend to choose the form that feels natural and efficient.

That’s one reason why ” who has expanded into positions traditionally assigned to whom.

Consider these everyday questions: Who did you see?Who did you call?Who did you talk to?Who else did you invite?

These sentences are so familiar that replacing who with whom can make them sound noticeably formal:

Whom did you see?

Whom did you call?

To whom did you speak?

The formal forms aren’t necessarily wrong. They’re simply less common in casual speech.

Modern Spoken English

Modern spoken English strongly favors who.

This isn’t limited to one particular phrase. It happens throughout the language.

People commonly say:

Who are you talking to?

rather than:

To whom are you talking?

They say:

Who did you meet?

rather than:

Whom did you meet?

And they say:

Who else did you invite?

rather than:

Whom else did you invite?

The conversational form tends to win because it is shorter, familiar, and easy to produce.

American English vs. British English

Both American and British English recognize the traditional distinction between who and whom, but actual usage varies by speaker, context, and level of formality.

In both varieties, whom remains more associated with formal language, while who is widely used in ordinary speech.

British English can preserve whom in formal constructions, especially after prepositions:

To whom should I address the letter?

American English uses the same formal construction, but everyday American speech commonly prefers:

Who should I address the letter to?

The important point is not to create a false division in which one variety “uses who” and the other “uses whom.” Both varieties have both forms. Register and context often matter more than nationality.

Why Is “Whom” Becoming Less Common?

English has gradually reduced many grammatical distinctions that once required different word forms.

The decline of whom fits that broader pattern.

Speakers already rely heavily on word order and context to understand grammatical roles. As the older case distinction weakened, who became increasingly common in object positions.

That development is visible in ordinary questions: Who did you call?Who did she invite?Who are you talking to?

The language doesn’t stop working because who appears in an object position. The sentence remains clear because the surrounding words reveal who performed the action and who received it.

Should You Stop Using “Whom”?

Not necessarily.

There’s no need to treat whom as a forbidden word.

It remains useful in formal constructions, especially:

to whom

with whom

for whom

of whom

from whom

It also remains common in certain fixed expressions and formal relative clauses:

the person whom I contacted

the candidate whom the committee selected

several of whom

The better lesson is this:

Know what “whom” does, recognize where it sounds natural, and don’t force it into sentences where “who” communicates more smoothly.

Common Mistakes People Make

Mistake 1: Using Whom to Sound More Formal

A common misconception is:

Whom always sounds smarter than who.

It doesn’t.

For example:

Whom else wants to come?

isn’t improved by its formality. In fact, traditional grammar would require who else because the pronoun is the subject of wants.

The correct sentence is:

Who else wants to come?

Formality cannot rescue an incorrect grammatical role.

Mistake 2: Confusing the Subject and the Object

Consider:

Who else called the manager?

The unknown person acts.

So:

Who else called?

Now compare:

Whom else did the manager call?

The manager acts. The unknown person receives it.

Traditional grammar therefore uses whom.

The easiest way to avoid this mistake is to identify who performs the verb.

Mistake 3: Forgetting the He/Him Test

When the sentence becomes complicated, the substitution test can save time.

Who else could answer the question?

→ He could answer the question.

Use who.

Whom else could we ask?

→ We could ask him.

Traditional grammar favors whom.

Mistake 4: Assuming Every Preposition Requires Whom

The traditional rule is useful, but modern English frequently moves prepositions to the end.

Formal:

With whom did you speak?

Natural:

Who did you speak with?

Formal:

To whom else should I send this?

Natural:

Who else should I send this to?

So don’t assume that every sentence containing a preposition must use whom.

Mistake 5: Overcorrecting Your Writing

Overcorrection happens when someone learns the who/whom distinction and starts replacing every who with whom.

That can produce sentences that sound unnatural:

Whom should I ask for help?

Traditional grammar supports this, but modern American English usually prefers:

Who should I ask for help?

The goal isn’t to eliminate formal grammar. The goal is to write English that matches the situation.

How to Avoid These Mistakes

Use this simple process:

First, identify the verb.

Next, determine who acts.

Then, determine whether the pronoun receives the action or follows a preposition.

Finally, consider your audience and level of formality.

If you’re writing ordinary American English, who else will usually be the most natural choice?

If you’re deliberately following traditional formal grammar, whom else may be appropriate when the pronoun functions as an object.

That distinction gives you a practical answer without turning a small grammar question into a maze of rules.

Who Else or Whom Else: Final Practical Guide

The simplest way to handle who else and whom else is to separate traditional grammar from modern usage. Traditionally, who serves as a subject and whom serves as an object. In everyday American English, however, who commonly replaces whom, even when it functions as an object. That makes who else the natural choice in most conversations, emails, articles, and general writing.

Who Else Is Usually the Best Choice

Use who else when you want your English to sound natural and direct.

Examples:

• Who else is coming?
• Who else wants to help?
• Who else knows the answer?
• Who else should we invite?
• Who else did you contact?
• Who else did you speak to?
• Who else can solve this problem?

The first three examples clearly use who else as a subject. The later examples show modern English using who as an object.

That distinction matters because “Who else did you invite?” is not an accidental mistake. It is a normal construction in contemporary English.

When Whom Else Is Appropriate

Use whom else when you want to follow the traditional object form, particularly in formal writing.

For example: Whom else did the committee interview?Whom else should the organization consult?To whom else should the letter be addressed?With whom else did the researcher speak?

These constructions are grammatically sound under traditional rules. They may fit legal, academic, official, or highly formal writing.

However, formal does not automatically mean better.

For many readers, these versions sound more distant than: Who else did the committee interview?Who else should the organization consult?Who else should I send the letter to?Who else did the researcher speak with?

A Simple Rule for “Who Else”

If you want one practical rule to remember, use this:

Use “who else” for most modern American English.

Then remember the traditional exception:

Use “whom else” when the pronoun is an object, and you intentionally want formal or traditional grammar.

This gives you a useful balance. You understand the grammar without forcing an old-fashioned construction into every sentence.

The He/Him Shortcut

When you’re unsure, replace the unknown person with he or him.

If he works:

Who else came?

→ He came.

If him works:

Whom else did you call?

→ You called him.

The same test works with they and them:

Who else arrived?

→ They arrived.

Whom else did you invite?

→ You invited them.

This test explains the traditional distinction quickly.

Why “Who Else” Usually Wins

Modern English tends to favor who else because people value speed, familiarity, and ease of understanding.

Compare:

Who else did you ask?

with:

Whom else did you ask?

Both communicate the same basic idea. The first feels more conversational. The second draws attention to the grammatical form.

That difference becomes even clearer in speech.

Most people naturally say:

Who else did you tell?

They don’t usually pause and think:

“The person is the object of the verb, so I need whom.”

Language develops through actual use, and modern speakers have broadly extended who into many positions once associated with whom.

Why “Whom” Hasn’t Disappeared

Although whom is less common, it still has a place in English.

You may encounter it in:

• Formal correspondence
• Legal documents
• Academic writing
• Official statements
• Formal questions
• Relative clauses
• Prepositional phrases
• Traditional grammar exercises

Examples include:

To whom should the application be sent?

With whom did you discuss the matter?

The candidate whom the committee selected accepted the position.

So it would be misleading to say that whom is simply wrong or obsolete. It remains part of standard English, particularly in formal contexts.

A Better Way to Think About “Else”

The word else doesn’t decide whether you need who or whom.

Instead, else adds the meaning of another, additional, or besides the person or people already under discussion.

Compare:

Who is coming?

with:

Who else is coming?

The first asks about the people coming.

The second asks about additional people coming.

The grammar of who remains the same.

Likewise:

Whom did you invite?

becomes:

Whom else did you invite?

Adding else doesn’t turn an object into a subject or change a subject into an object.

Common Real-World Examples

Conversation

Who else is going to the concert?

Workplace

Who else needs access to this file?

School

Who else has completed the assignment?

Email

Who else should I copy on this message?

Formal report

Whom else did the committee interview?

Formal correspondence

To whom else should the documents be sent?

These examples demonstrate how context influences the best choice.

The Most Common Mistake

The biggest mistake is treating whom as a more sophisticated replacement for who.

For example:

Whom else wants to participate?

This sounds formal, but it is not correct under traditional grammar because whom else is the subject of wants.

The correct form is:

Who else wants to participate?

On the other hand:

Whom else did you invite?

does fit the traditional object rule.

So the question isn’t:

“Which word sounds more formal?”

The better question is:

“What grammatical role does the pronoun have?”

After that, consider whether your audience expects formal or everyday English.

The Bottom Line

“Who else” is the correct and natural choice in most modern American English. Use it freely in conversation, workplace writing, emails, educational content, and general articles. “Whom else” is also grammatically valid when whom functions as an object under traditional grammar, especially in formal writing or after a preposition.

Then consider your audience. For everyday American English, who else will usually sound more natural.

Conclusion

Choosing between “who else” and “whom else” becomes much easier once you understand the role of the pronoun. In traditional grammar, who functions as a subject, while whom functions as an object. However, modern American English strongly favors who else in everyday speech and most general writing, even when it acts as an object. “Whom else” still has a place in formal writing, especially after prepositions or when following traditional grammatical rules. If you’re writing for a broad audience, “who else” will usually sound clearer, warmer, and more natural. When you’re unsure, use the he/him or they/them test to identify the traditional grammatical role, then consider the tone of your sentence. The goal isn’t to make every sentence sound formal. It’s to choose the version that communicates your meaning naturally and confidently.

FAQs

Is “who else” grammatically correct?

Yes. “Who else” is grammatically correct and is the normal choice in modern English. It works clearly when who functions as a subject, such as “Who else is coming?” Modern speakers also commonly use it when traditional grammar would suggest whom, as in “Who else did you invite?”

Is “whom else” grammatically correct?

Yes. “Whom else” is grammatically correct when whom functions as an object under traditional grammar. For example, “Whom else did you invite?” follows the traditional subject-object distinction. However, this construction sounds more formal than “Who else did you invite?” and is less common in everyday American English.

Which is more common, “who else” or “whom else”?

“Who else” is much more common in modern everyday English, particularly in American English. People regularly use it in conversation, emails, workplace communication, and general writing. “Whom else” still appears in formal or traditional writing, but many readers may perceive it as more formal or somewhat old-fashioned.

Should I say “who else did you invite” or “whom else did you invite”?

Both forms have grammatical justification, depending on the style you follow. Traditional grammar favors “whom else did you invite?” because the person is the object of “invite.” Modern English generally prefers “who else did you invite?” For ordinary American English, the version with who is usually the more natural choice.

Is “who else” correct in formal writing?

Yes. “Who else” can be completely appropriate in formal writing, especially when it functions as the subject. Even in object positions, modern formal writing often accepts who. If you’re deliberately following traditional grammar, however, whom may be preferable when it functions as an object.

When should I use “whom else”?

Use “whom else” when following traditional formal grammar and the pronoun functions as an object. It is particularly natural after a preposition in formal constructions, such as “To whom else should I speak?” In ordinary American English, however, “Who else should I speak to?” is generally more conversational.

Does “else” change whether I use who or whom?

No. “Else” doesn’t determine whether you should use who or whom. It simply means another or additional person or people. The grammatical role still matters. For example, “Who else is coming?” uses who as a subject, while traditional grammar analyzes Whomm else did you invite?” as an object.

What is the easiest way to remember who versus whom?

Use the he/him test. If you could replace the pronoun with he, traditional grammar favors who. If you could replace it with him, traditional grammar favors whom. You can also use they/them. Remember that modern English often uses who where traditional grammar would use whom.

Is “who else should we ask” correct?

Yes. “Who else should we ask?” is correct and natural modern English. Traditional grammar can justify “Whom else should we ask?” because the pronoun functions as the object of “ask.” Nevertheless, the version with who is much more common in everyday American English and works well for most general writing.

Is “to whom else” correct?

Yes. “To whom else” is a traditional and formal construction because whom follows the preposition to. For example, “To whom else should I send the letter?” is grammatically correct. In conversational English, people commonly say, “Who else should I send the letter to?” instead.
