Who Else vs Whom Else: Which Is Correct?

Who Else vs Whom Else: Which Is Correct?

The choice between who else and whom else depends on grammatical case, but modern English gives writers more than one practical option. In the debate over Else vs Whom Else, who else is the normal choice when the pronoun is the subject of the verb, while whom else is traditionally used when it is the object. Yet “Who else did you invite?” is common and accepted in ordinary English, even though formal grammar may prefer “Whom else did you invite?”

This distinction matters in interviews, emails, academic writing, and formal correspondence. You will learn when each form works, why spoken English often favors who, and how to choose a version that sounds both grammatical and natural.

The Short Answer: Who Else or Whom Else?

Use who else when the pronoun performs the action or serves as the subject of the verb. For example, in “Who else wants coffee?” the person represented by who is the one who wants coffee.

Use whom else when the pronoun receives the action or follows a preposition. In “Whom else did Maya contact?” the unknown person is the object of contacted, so traditional grammatical case calls for whom.

That is the formal distinction. In everyday American English, however, who else is widely used even before an object, as in “Who else did Maya contact?” Many speakers regard that version as natural standard English rather than an error.

Expression	Typical grammatical role	Example	Practical use
Who else	Subject pronoun	Who else is joining us?	Normal in speech and general writing
Whom else	Object pronoun	Whom else did you notify?	Formal, careful, or traditional writing
Who else	Object in informal usage	Who else did you invite?	Common and natural in modern English
With whom else	Object after a preposition	With whom else did she speak?	Most formal and grammatically explicit

If you need one safe rule, use who else for a subject and whom else for a formal object. If your workplace, school, publication, or client follows a style guide, that house style should control the final choice.

What “Who Else” Means

Who else asks about another person in addition to someone already known, mentioned, or implied. The word else means “in addition to the person or people already under discussion.” In “Who else is attending the conference?” the speaker knows that at least one person is attending and wants to identify additional attendees.

Here, who is an interrogative pronoun because it introduces a question about a person. It is also a subject pronoun because it performs the action expressed by the verb. The implied structure is close to “Who else is attending?” and the answer might be “Jordan and Priya are attending.”

The form appears in many ordinary questions:

Who else approved the proposal?
Who else needs a copy of the report?
Who else can help with the presentation?
Who else knows the access code?
Who else will be affected by the schedule change?

In each example, the person identified by who is connected to the verb as its subject. “Who else approved” means “Which other person approved,” while “Who else can help” means “Which other person can help.” The word else does not change the basic grammatical role of who.

Who else can also appear in an object position in informal English. “Who else did you call?” is extremely familiar to English speakers, even though call takes an object and traditional grammar would identify the person as whom.

What “Whom Else” Means

Whom else has the same broad meaning as who else, but it marks the person as an object. In “Whom else did the committee interview?” the committee is the subject of interviewed, and the unknown person is the object.

The distinction becomes clearer if you replace the interrogative pronoun with a personal pronoun. “The committee interviewed her” sounds correct, while “The committee interviewed she” does not. Because her is an object pronoun, traditional grammatical case supports “Whom else did the committee interview?”

Whom else is especially natural after a preposition:

With whom else should I discuss the matter?
For whom else was the form prepared?
To whom else did you send the invoice?
About whom else were the employees asking?

In formal written English, a fronted preposition often makes whom the clearest choice. “With whom else did you speak?” displays the grammatical relationship directly. The less formal “Who else did you speak with?” is also common, particularly in conversation and general business communication.

Whom is not a separate word meaning “another person.” Both who and whom refer to a person, and else adds the idea of an additional person. The difference is grammatical case, not meaning.

Who Else vs Whom Else in Real Sentences

The easiest way to understand the contrast is to examine complete sentences in realistic settings. Consider a staff meeting: “Who else is presenting today?” The pronoun is the subject of is presenting, so who is the traditional and modern choice.

Now consider a hiring process: “Whom else did the panel interview?” The panel performed the action, and the person being interviewed received it. That makes whom the formal object pronoun.

Workplace communication

“Who else should receive the project update?” is a natural workplace question. The implied meaning is “Which other person should receive it?” Although receive has an object, who is the subject of should receive, because the person in question is the one who should perform the receiving.

“Whom else should we copy on the email?” follows a different structure. We is the subject of copy, and the person represented by whom is the object. In everyday office writing, “Who else should we copy?” is more common and rarely causes confusion.

Academic and formal writing

“Who else has challenged this interpretation?” uses who correctly because the pronoun is the subject of has challenged. By contrast, “Whom else does the author cite?” uses whom in the formal object position.

Some academic editors preserve this distinction consistently, especially in carefully edited prose. Others accept who in object questions because contemporary standard usage has weakened the case contrast in ordinary contexts.

Public and internal announcements

“Who else can register for the training?” asks which additional people are eligible or able to register. “Whom else will the training benefit?” uses whom in a formal object structure, although “Who else will the training benefit?” is the version many readers would naturally write.

The choice should match the audience. A legal notice, formal invitation, or traditional academic essay may benefit from whom. An employee message, website heading, or spoken announcement will usually sound more direct with who.

How to Test the Grammatical Case

A useful test is to replace who or whom with a personal pronoun. If you would use he or she, choose who. If you would use him or her, choose whom.

Who else is responsible? He is responsible, so use who.
Whom else did you notify? You notified her, so formal grammar favors whom.
Who else submitted the form? She submitted it, so use who.
With whom else did they meet? They met with him, so use whom.

This test works because English still distinguishes subject and object pronouns in several forms. The subject pronouns include I, he, she, we, and they. The corresponding object pronouns include me, him, her, us, and them.

The verb itself can make the structure harder to see. In “Who else did you ask?” the word you is the subject of ask, even though it appears after who. The missing person is the object, which explains why formal grammar would use whom.

Word order can hide the relationship. English questions often move the interrogative pronoun to the front, so the first word is not necessarily the subject. Ask yourself who performs the verb, not simply which word appears first.

Is “Who Else” Acceptable as an Object?

Yes. Who else is widely accepted in modern English when it functions as an object, especially in spoken English and informal or general professional writing. “Who else did you invite?” is familiar, clear, and natural to most readers.

Traditional prescriptive grammar distinguishes “Who else did you invite?” from “Whom else did you invite?” The first uses who as an object, while the second preserves the formal object form. Many speakers do not maintain that distinction consistently because who has become the default interrogative pronoun in a large range of questions.

This is similar to the broader pattern of whom vs who. The form whom remains strongest after a preposition or in highly formal writing, but it is less frequent in casual speech.

A writer should not assume that choosing whom automatically makes a sentence better. If it makes the sentence sound stiff or distracts the reader, rewriting may be wiser.

For example, instead of choosing between “Who else did the director consult?” and “Whom else did the director consult?”, you could write “Which other advisers did the director consult?” That alternative avoids the case issue while preserving the meaning.

Formal English, Informal English, and Professional Style

Formal English often favors whom when the grammatical role is clearly objective. A formal letter might say, “With whom else should the request be discussed?” A spoken version would more likely be, “Who else should we discuss the request with?”

Professional writing sits between those extremes. An executive report can use “whom else” accurately, but an internal email may sound more natural with “who else.” Neither choice is automatically unprofessional.

Audience expectations matter. If your readers include editors, academics, lawyers, or people working under a strict style guide, maintaining the traditional distinction can signal careful editing. If the audience values plain language and quick comprehension, who may be the better choice in object questions.

Use the following considerations before making a decision:

Grammar: Is the pronoun the subject of the verb, the object, or the object of a preposition?
Register: Does the sentence belong to formal writing, workplace communication, or conversation?
House style: Has the organization already chosen a preferred approach?
Naturalness: Does whom sound deliberate and appropriate, or unusually stiff?
Consistency: Will similar questions throughout the document follow the same policy?

Professional writing benefits more from a clear, consistent policy than from forcing whom into every sentence. A document that uses who naturally in one paragraph and whom mechanically in the next may look less controlled than a document that follows one deliberate standard.

American English and British English

There is no simple rule that assigns who else to American English and whom else to British English. Both forms appear across major varieties of English, and the difference is influenced by formality, education, publication standards, and individual preference.

American English often uses who broadly in speech and everyday writing, including object questions. British English also uses who in many informal contexts, while whom remains available in formal writing and after prepositions.

Regional variation exists, but grammatical position still matters in both varieties. “Who else is coming?” is a subject question in American and British English. “With whom else did you speak?” is formal in both varieties.

Established references can help writers understand the range of usage. Merriam-Webster’s entry for whom explains the traditional object function while also reflecting how actual English usage has changed. The Oxford English Dictionary provides historical evidence for how words develop, but a dictionary entry should not be treated as a substitute for the style requirements of a particular publication.

Do not assume that whom else is exclusively British or that who else is exclusively American. That claim oversimplifies English grammar and ignores the role of context. A formal British report may use who in an object question, and an American legal document may carefully preserve whom.

Alternatives That Avoid the Choice

Sometimes the clearest solution is to rewrite the sentence. This is useful when the audience may find whom formal or when who creates a sentence that feels ambiguous.

Original pattern	Clear alternative	Why it helps
Whom else did you invite?	Which other guests did you invite?	Removes the pronoun case issue
With whom else did she meet?	Who else did she meet with?	Sounds more natural in conversation
Who else is affected?	Which other teams are affected?	Adds useful specificity
Whom else should we contact?	Which other contact should we reach?	Works well in forms and instructions

“Which other” is often the strongest alternative because it can identify the category being discussed. “Which other departments should be included?” is more precise than “Whom else should we include?” when the answer concerns departments rather than individuals.

You can also restructure a prepositional phrase. Instead of “With whom else did the consultant speak?”, write “Who else spoke with the consultant?” The revised sentence changes the grammatical focus and makes who the subject.

Other useful phrases include “which additional person,” “which other participants,” “anyone else,” “another individual,” and “additional contacts.” Choose the phrase that gives readers the information they need, not simply the phrase that avoids a grammar decision.

Common Mistakes with Who Else and Whom Else

Using whom because it sounds formal

Some writers insert whom whenever a sentence sounds serious. That approach can create errors, as in “Whom else is attending?” Because the pronoun is the subject of is attending, traditional grammar calls for who.

Formal tone does not change grammatical function. Test the sentence with he or him before choosing.

Assuming who is always correct

The opposite mistake is treating who as the answer in every context. “Who else did the manager call?” is accepted in ordinary English, but “To who else did the manager send the notice?” is generally considered less polished than “To whom else did the manager send the notice?”

After a preposition, whom remains the clearer formal choice. You can also move the preposition to the end if that suits the register: “Who else did the manager send the notice to?”

Writing “who else” as two unrelated ideas

Who else is written as two words because who is the pronoun and else is an adverb modifying it. It is not normally written as a single word. Forms such as “whoelse” and “whomelse” are incorrect.

Changing forms without a reason

A document may contain “Who else approved the plan?”, “Whom else did the board consult?”, and “Who else was notified?” That mixture is not automatically wrong, because the sentences have different grammatical structures. However, unexplained shifts between who and whom in similar object questions can make the editing look inconsistent.

Set a policy before editing a long document. For example, you might preserve whom after prepositions and use who in ordinary questions unless a formal distinction is needed.

How to Choose the Right Form

Use a short decision process whenever you hesitate over who else and whom else.

Find the verb. Identify the action or state connected to the pronoun.
Ask who performs it. If the unknown person performs the verb, use who.
Check for an object relationship. If the unknown person receives the action, formal grammar favors whom.
Look for a preposition. After with, to, for, by, or about, whom is usually the formal form.
Consider the audience. Choose the register that fits the document and readers.
Apply house style consistently. Record the decision if several people will edit the document.

Try the substitution test. “Who else called?” becomes “She called,” so who is correct. “Whom else did she call?” becomes “She called him,” so whom is the formal choice.

If the sentence still feels awkward, rewrite it. “Which other employees did she call?” may be more useful than either pronoun, especially in a policy, survey, or customer-facing form.

Examples for Emails, Reports, and Workplace Documents

Real workplace writing often involves questions about responsibility, communication, attendance, and approval. The following examples show how the choice changes with grammatical function and level of formality.

Email: “Who else should I include on the project update?” This is natural and direct.
Formal email: “To whom else should I direct the completed form?” This uses whom after the preposition to.
Meeting notice: “Who else will attend the supplier review?” The pronoun is the subject of will attend.
Business report: “Whom else did the research team interview?” This preserves the formal object distinction.
Policy document: “Employees must identify who else has access to the records.” Who is the subject of has access.
Human resources message: “Who else is eligible for the benefits briefing?” The sentence asks for additional eligible people.
Customer service note: “Who else did the customer contact?” This informal object use is clear and widely accepted.
Legal correspondence: “With whom else was the agreement discussed?” The formal preposition-plus-whom structure may suit the setting.

Notice that the formal version is not always the best version. “To whom else should I direct the form?” is precise, but “Who else should receive the form?” is often clearer and less ceremonial.

Professional writing should serve the reader. Grammar is part of that service, but so are directness, readability, and a tone appropriate to the relationship.

Who Else and Whom Else in Formal Writing

Formal writing does not require every traditional distinction in every sentence. It requires deliberate choices that fit the audience, genre, and editorial expectations.

In a university paper, “Whom else does the theory exclude?” may be appropriate if the writer is maintaining formal grammatical case. In a public information page, “Who else does the program serve?” may be more accessible and equally clear.

Legal and regulatory documents deserve particular care because wording can affect interpretation. Even there, a writer should not use whom simply to sound official. The sentence should be checked for structure, and a rewrite should be considered if the pronoun creates unnecessary difficulty.

Style guides vary in how strongly they preserve whom. Some favor traditional case distinctions in edited prose, while others recognize that who is dominant in ordinary usage. If you are writing for a publication, institution, or employer, follow its style guide rather than relying on personal preference.

For independent writers, a sensible policy is to use who for subjects, reserve whom for clear formal objects and objects after prepositions, and rewrite sentences that sound forced. That approach respects traditional grammar without ignoring contemporary standard English.

Frequently Asked Questions

Is “who else” or “whom else” correct?

Both can be correct. Use who else when the pronoun is the subject, and use whom else for a formal object or an object after a preposition. In everyday English, who else is also widely accepted in object questions.

Is “whom else” more formal?

Usually, yes. Whom else preserves the traditional object-pronoun distinction, so it often sounds more formal or carefully edited. That does not mean it is always better, particularly when the sentence becomes stiff.

Should I write “Who else did you invite?” or “Whom else did you invite?”

Both appear in standard usage. “Whom else did you invite?” follows traditional grammatical case, while “Who else did you invite?” is more natural for many speakers and readers. Use the version required by your style guide or audience.

Can “who else” be the subject of a verb?

Yes. In “Who else approved the request?” and “Who else is available?”, who is the subject of the verb. This is the clearest and least controversial use of who else.

Can “whom else” follow a preposition?

Yes. “With whom else did you speak?” and “To whom else should we send the notice?” use whom as the object of a preposition. In less formal English, speakers often move the preposition to the end and use who instead.

Is “who else” one word?

No. The correct form is two words: who else. Who is the interrogative pronoun, and else modifies it. “Whoelse” is not a standard spelling.

Is “who else” wrong in informal English?

No. It is common and natural, including in questions where traditional grammar would use whom. Spoken English strongly favors who in many such contexts, and general professional writing often accepts it.

What is the best alternative to “whom else”?

Use “which other person,” “which other participants,” or “who else” depending on the sentence. Rewriting can make the meaning clearer without forcing a decision about formal case.

Should I use one form consistently throughout a document?

Use a consistent policy, but consistency does not mean using the same pronoun in every grammatical position. You can use who for subjects and whom after prepositions while applying that distinction consistently throughout the document.

Practical Takeaway

The central distinction in Else vs Whom Else is grammatical case. Choose who else when the person is the subject, and choose whom else when formal writing requires an object pronoun, especially after a preposition.

In ordinary spoken English and much workplace writing, who else is accepted in object questions such as “Who else did you contact?” If your organization or publication has a house style, follow it. Otherwise, favor the form that is grammatically defensible, natural for the audience, and consistent throughout the document.
