Who vs Whom: What’s The Difference?


Hey everyone! Ever find yourself scratching your head over English words that sound almost the same but have different uses? You’re not alone. English is packed with these tricky pairs that can make anyone pause. They’re like word puzzles waiting to be solved.

Today, we’re diving into one such puzzling pair:

“Who” and “Whom.”

These two might seem like they’re playing a game of musical chairs in sentences, but each has its own place and purpose. 

“Who” is like the outgoing friend who’s always the subject of the sentence – the one doing the action.

 “Whom” is more like the chill friend who’s often the object – the one receiving the action.

So, if you’re up for untangling the mystery of “Who” vs “Whom,” stick around. We’re about to make sense of when to use each word, without getting lost in grammar jargon. Let’s go!

Definition of Who

Awesome, let’s jump into “Who.” This word is a bit like a detective in a sentence, always asking questions about people. When you use “who,” you’re usually asking or talking about the person who is doing something or the one in the spotlight.

For example, if you ask, “Who made this awesome playlist?” you’re trying to find out the person behind the action, the one who created the playlist. Or in a sentence like, “She’s the one who solved the mystery,” “who” is pointing out the person who did the solving.

You’ll see “who” pop up a lot in questions. It’s always poking around to find out about people. It’s also used in statements to point out someone involved in an action.

 The key thing to remember is that “who” is always about the subject – the person doing the action. It’s never about the person receiving the action.

Definition of Whom

Now, let’s tackle “Whom.” This word is like the undercover agent in sentences. It’s less common than “who,” but it has a special role: “whom” is used when you’re talking about someone who is the object of the action – basically, the person receiving the action.

For example, if you’re asking, “To whom should I address this letter?” you’re trying to find out who will receive the letter. Or in a sentence like, “Whom did you invite to the party?” “whom” is asking about the people who were invited, not the one doing the inviting.

“Whom” often shows up in more formal or traditional writing and speaking. It’s like the formal hat you put on your sentence when you want to be extra correct. You’ll typically see “whom” after prepositions, like in “For whom is this package?” or “With whom are you going to the concert?”

In everyday conversation, a lot of people just use “who” instead of “whom,” even when “whom” is technically correct. But for formal writing, knowing how to use “whom” properly can really polish up your style.

 So, remember: if the person is receiving the action, “whom” is the word you want. It’s all about the receiver, not the doer.

Etymology and Historical Usage

Let’s dive into the history of “who” and “whom” to see how they came to be and how their usage has evolved over time.

Starting with “who,” this word has deep roots in the English language, tracing back to Old English as “hwa.” It comes from the Proto-Germanic “*hwaz,” which is related to the Latin “quis” and the Greek “kis,” indicating a long-standing use across different languages to ask about a person. 

Historically, “who” has always been about identifying or asking about the subject of a sentence – the person doing the action. Its role has been pretty consistent over the centuries, making it a staple in question formation and identification in English.

Moving on to “whom,” this word also originates from Old English, known then as “hwam” or “hwæm,” which was the dative case of “hwa” (who). The dative case is used to indicate the indirect object of a verb – essentially, the receiver of the action. 

“Whom” has retained this role throughout the history of English, although its usage has become more formal and less common in everyday speech. 

In modern times, “whom” is often replaced by “who” in casual contexts, but it still holds its ground in formal writing and when following prepositions.

Comparative Analysis

When comparing “Who” and “Whom,” it’s all about understanding their roles in a sentence and the subtle nuances they bring.



“Who” is direct and straightforward. It’s used to identify or inquire about the subject of a sentence — the person doing something.


It’s commonly used in questions and statements, fitting naturally into everyday conversation.


“Who made these cookies?”

(Asking about the person who did the action of making cookies.)



“Whom” carries a more formal or traditional tone. It’s used for the object of a verb or preposition — the person receiving the action.


Often found in formal writing, legal documents, or structured sentences, especially after prepositions.


“Whom did you give the book to?”

(Asking about the person who received the book.)

Side-by-Side Comparison

Who (Subject):

“Who is going to the concert?”

(Asking about the person doing the action of going.)

Whom (Object):

“To whom should I send this letter?”

(Asking about the person receiving the action of the letter being sent.)

In essence, “who” is your everyday, versatile word for asking about the doer in a scenario, while “whom” is more formal and specific, used when you’re talking about someone on the receiving end of an action. 

Common Mistakes and Misuses

Understanding the difference between “Who” and “Whom” can be tricky, but being aware of common mistakes and knowing some tips can help you use these words correctly.

Common Errors

Using “Who” Instead of “Whom”: A common mistake is using “who” where “whom” should be used, especially after a preposition or as the object of a sentence. For example, saying “Who did you send the invitation to?” instead of “Whom did you send the invitation to?”

Using “Whom” Instead of “Who”:

Sometimes, people use “whom” when “who” is correct, often in an attempt to sound more formal or correct. For instance, saying “Whom is at the door?” instead of “Who is at the door?”

Tips for Remembering

For “Who”:

Think of “who” as the word for the person doing the action. It’s the subject of the verb. A quick trick is to answer your question with “he” or “she.” If “he” or “she” fits, then “who” is likely correct.

For “Whom”:

Use “whom” when you’re talking about the person receiving the action. It’s the object of the verb or preposition. To test it, answer the question with “him” or “her.” If “him” or “her” fits, “whom” is the word to use.

Mnemonic Device

“Who” and “he” both have an ‘o,’ and “whom” and “him” both end with ‘m.’ So, if you can replace “who” with “he” (or “she”), and “whom” with “him” (or “her”), you’ve got the right word.


Correct: “Who is coming to the party?”

(“He is coming to the party.”)

Correct: “Whom did you see?”

(“I saw him.”)

By keeping these tips in mind, you can avoid common mistakes and confidently use “who” and “whom” in your writing and conversations. Remember, “who” is for the doer, and “whom” is for the receiver.

Practical Tips for Distinguishing Between Who and Whom

To make it easier to distinguish between “Who” and “Whom,” here are some practical tips and a mnemonic device, along with a comparison table to help you remember when to use each word correctly.

Practical Tips:

  • Substitution Method: Try substituting “he/she” for “who” and “him/her” for “whom.” If the sentence still makes sense, you’ve chosen the right word.
    • For “Who,” think “He/She” (all have vowels ‘o’ or ‘e’).
    • For “Whom,” think “Him/Her” (all end with ‘m’ or ‘r’).

Mnemonic Device:

  • Who vs. He/She: Both “who” and “he/she” have a vowel in the middle (o, e).
  • Whom vs. Him/Her: Both “whom” and “him/her” end in a consonant (m, r).

Comparison Table:

Function in a SentenceSubject (the one doing the action)Object (the one receiving the action or after a preposition)
ExampleWho wrote the book? (He/She wrote the book.)Whom did you call? (You called him/her.)
MnemonicWho = He/She (Vowel sounds)Whom = Him/Her (End consonant sounds)
UsageMore common in everyday speechMore formal, often used in writing or formal speech

Extra Tip:

  • In modern conversation, “whom” is becoming less common, and many people use “who” in most cases. However, in formal writing or situations where you want to be grammatically correct, it’s good to use “whom” properly.

By using these guidelines and the mnemonic device, you can more easily choose between “who” and “whom” in your writing and speaking. Remember, “who” is for the subject doing the action, while “whom” is for the object receiving the action or following a preposition.

Usage in Literature and Media

In literature, movies, and other forms of media, “Who” and “Whom” have been used in various ways, each enhancing the narrative with their specific grammatical roles.


In Literature: “Who” is commonly used in dialogues and narrative text. For example, in Arthur Conan Doyle’s Sherlock Holmes stories, you might find, “Who left this hat here?” reflecting a direct inquiry about the subject.

In Movies/Media: Characters often use “who” in conversation, as it’s more common in spoken English. For instance, a character might ask, “Who are you?” in a dramatic introduction scene.


In Literature: “Whom” appears in more formal or stylistically complex texts. In classic literature like Jane Austen’s novels, you might find sentences like, “To whom did you send the invitation?” which matches the formal tone of the period.

In Movies/Media: In more formal or historical contexts, characters might use “whom.” For example, in a period drama, a character might say, “With whom shall I have the pleasure of dancing?” reflecting the formal speech of the era.

Examples in Use:

Who (Subject):

“Who knows the truth about the incident?”

(Mystery Novel)

Whom (Object):

“For whom does the bell toll?”

(Historical Drama)

These examples show how “who” and “whom” are used differently to suit various narrative styles and settings.

 “Who” is more prevalent in everyday language and dialogue, while “whom” tends to appear in formal or traditional contexts. 

Understanding these differences can enhance both the comprehension and the enjoyment of various literary and media works.
