Who vs. Whom – Which is Correct?

“Who” and “whom” are often confused, but the distinction is simple: who acts as the subject of a verb (like “he” or “she”), while whom acts as the object of a verb or preposition (like “him” or “her”). Use “who” when referring to the doer of an action, and “whom” when referring to the receiver.

Who or Whom – Which is Correct?

The confusion between “who” and “whom” stems from their similar sounds and roles as pronouns referring to people. However, their correct usage depends entirely on their grammatical function within a sentence. Think of it like the difference between “I” and “me,” or “he” and “him.”

• Who is a subjective pronoun. This means it acts as the subject of a verb, performing the action. It’s the equivalent of “he,” “she,” or “I.”
• Whom is an objective pronoun. This means it acts as the object of a verb or a preposition, receiving the action or being governed by the preposition. It’s the equivalent of “him,” “her,” or “me.”

The Best Trick to Remember the Difference

The most reliable way to determine whether to use “who” or “whom” is the “he/him” or “she/her” swap test.

1. Identify the clause containing “who” or “whom.”
2. Try to substitute “he” or “she” into that clause. If the sentence still makes sense, then who is the correct choice.
3. If you can substitute “him” or “her” into the clause, then whom is the correct choice.

Example 1: (Who/Whom) is coming to the party?

• Try “He is coming to the party.” (Makes sense)
• Try “Him is coming to the party.” (Doesn’t make sense)

Therefore, the correct word is Who.

Example 2: To (who/whom) did you speak?

• Rephrase: “You spoke to (he/him).”
• Try “You spoke to he.” (Doesn’t make sense)
• Try “You spoke to him.” (Makes sense)

Therefore, the correct word is Whom.

Word	Part of Speech	Meaning	Example
Who	Subjective Pronoun	Refers to the subject of a verb (the doer of an action).	Who called the police?
Whom	Objective Pronoun	Refers to the object of a verb or preposition (the receiver of an action).	To whom did you give the book?

How to Use Who

“Who” is a versatile pronoun used to refer to people. It serves as the subject of a verb, meaning it performs the action. It can function as both an interrogative pronoun (asking a question) and a relative pronoun (introducing a clause that provides more information about a person). In modern English, particularly in casual conversation, “who” is often used even where “whom” might technically be correct, though this is generally avoided in formal writing.

Example 1: Who wrote this incredible article? (Here, “who” is the subject of the verb “wrote.”)

Example 2: The student who aced the exam received a scholarship. (“Who” is the subject of the verb “aced” within the relative clause.)

Example 3: Can you tell me who is responsible for the project? (“Who” is the subject of the verb “is responsible” in the embedded question.)

What are the different forms of Who?

“Who” itself is the subjective form. Its other related forms are:

• Whose: The possessive form, indicating ownership or association. (e.g., Whose book is this?)
• Whom: The objective form, used when the pronoun is the object of a verb or preposition.

Etymology of the word Who

The word “who” traces its roots back to Old English as “hwā,” an interrogative pronoun. It is derived from the Proto-Germanic “hwaz” and further from the Proto-Indo-European “kʷos,” which also gave rise to other interrogative words like “what” and “which.” Its form has remained relatively stable over centuries, reflecting its fundamental role in questioning and relating information about individuals.

How to Use Whom

“Whom” is the objective form of “who” and is used when the pronoun is the object of a verb or, more commonly, the object of a preposition. Its usage signals a more formal tone and is largely preserved in formal writing, academic contexts, and legal documents. While less frequent in everyday conversation, correctly using “whom” demonstrates a strong command of grammar.

Example 1: To whom should I address this letter? (“Whom” is the object of the preposition “to.”)

Example 2: He is the colleague whom I mentioned yesterday. (“Whom” is the object of the verb “mentioned” – I mentioned him.)

Example 3: With whom did you attend the conference? (“Whom” is the object of the preposition “with.”)

What are the different forms of Whom?

“Whom” is the objective case of the pronoun “who.” It does not have further inflected forms in the same way verbs have tenses or nouns have plurals. It is simply the specific form used when the pronoun functions as an object.

Etymology of the word Whom

“Whom” originates from the Old English “hwām,” which was the dative case of “hwā” (who). This dative case indicated the indirect object of a verb or the object of certain prepositions in Old English. As the English language evolved and its case system simplified, “whom” remained as the distinct objective form, particularly after prepositions, preserving a remnant of its historical grammatical function. It comes from the Proto-Germanic “hwamm,” the dative form of “hwaz.”

Related Concepts

Understanding related grammatical concepts helps to clarify the correct usage of “who” and “whom” and solidifies your grasp of English sentence structure.

• Pronouns: Words that replace nouns (e.g., he, she, it, they). “Who” and “whom” are specific types of pronouns—interrogative and relative pronouns—that refer exclusively to people.
• Subject vs. Object: The subject of a sentence or clause is the noun or pronoun performing the action of the verb. The object is the noun or pronoun receiving the action or being affected by it. This fundamental distinction is the key to differentiating between “who” (subject) and “whom” (object).
• Prepositions: Words (like “to,” “with,” “for,” “by,” “from”) that connect a noun or pronoun to another word in a sentence, establishing a relationship. When a pronoun follows a preposition, it must always be in the objective case, hence the common usage of “whom” after prepositions.

Examples from Media and Literature

Observing “who” and “whom” in published works can help cement understanding of their correct application in various contexts.

• “Ask not for whom the bell tolls; it tolls for thee.” – John Donne, Devotions Upon Emergent Occasions (1624)
• “The question is not who will let me; it is who will stop me.” – Ayn Rand (often attributed)
• “We elect presidents, and whoever we elect, that’s who we’re stuck with for four years.” – Barack Obama (2012)
• “For whom the show must go on.” – Queen, The Show Must Go On (1991)
• “Who wants to live forever?” – Queen, Who Wants to Live Forever (1986)

Who Synonyms

“Who” is a unique functional pronoun, and direct, single-word synonyms that can perfectly replace it while maintaining grammatical structure are rare. However, its role can be described by related terms or phrases that highlight its function.

Synonym	Definition
Subjective Interrogative Pronoun	A pronoun used to ask about the identity of the person performing an action.
Subjective Relative Pronoun	A pronoun introducing a clause that refers to a person acting as the subject.
Agent (Person)	Refers to the person performing an action, in the context of “who” as the subject.

Whom Synonyms

Similar to “who,” “whom” is a specific grammatical tool rather than a word with a wide range of direct synonyms. Its “synonyms” are best understood as terms describing its role as an object.

Synonym	Definition
Objective Interrogative Pronoun	A pronoun used to ask about the identity of the person receiving an action or affected by a preposition.
Objective Relative Pronoun	A pronoun introducing a clause that refers to a person acting as the object.
Patient (Person)	Refers to the person receiving an action or being affected by it, in the context of “whom” as the object.

Frequently Asked Questions

Question 1: Is “whom” becoming obsolete?
While “whom” is less common in casual speech, especially in American English, it remains grammatically correct and is preferred in formal writing, academic papers, and professional communication, particularly after prepositions. Its usage is declining, but it is not entirely obsolete and still holds importance in demonstrating precise grammatical command.

Question 2: How do I handle “whoever” vs. “whomever”?
Apply the same “he/him” or “she/her” test to the clause containing “whoever/whomever.” If “he” or “she” fits within that specific clause, use “whoever.” If “him” or “her” fits, use “whomever.” For example: “Give it to whoever wants it.” (In the clause “whoever wants it,” “he wants it” makes sense, so “whoever” is correct, even though it’s the object of “to” in the larger sentence).

Question 3: Can I always use “who” and avoid “whom”?
In very informal contexts, using “who” instead of “whom” might pass unnoticed by many listeners. However, for formal writing, academic submissions, professional correspondence, or whenever clarity and grammatical precision are paramount, correctly using “whom” is essential. Avoiding “whom” entirely can make your writing appear less polished or even incorrect in discerning circles.

Conclusion

Mastering the distinction between “who” and “whom” boils down to understanding their roles as subjective and objective pronouns. Remember the simple “he/him” or “she/her” swap test, and you’ll confidently navigate even the trickiest sentences. While “whom” may seem formal, its correct application is a hallmark of precise and sophisticated English.

Pro Tip: In professional and academic settings, the accurate use of “who” and “whom” significantly enhances your credibility and demonstrates a strong command of the English language, leaving a positive impression on your audience.
