Who vs who; the difference

Who and whom are commonly confused words. In fact, many native English speakers don’t know the difference between them.

However, there is a simple way to determine which word is correct. You should use who to refer to the subject of a sentence, and whom to refer to the object of a sentence.

If you want your writing to sound professional, getting words like who and whom correct is important. Let’s look at these two words in more depth to understand how they work in a sentence.

The Difference Between Who and Whom

Who and whom have the same meaning and are both often used in questions, but in different ways. To choose the correct word, you need to know whether you are referring to the subject or object of the sentence.

  • Subject: The person is completing the action in the sentence. Subject pronouns include I, he, she, and they. When describing the subject of a sentence, you need to use the pronoun who.
  • Object: The person is receiving the action of the verb. Object pronouns include me, him, her, and them. Use the pronoun whom when describing the object of a sentence.

Difference between who vs whom

Let’s look at two examples to spot the difference between the subject and object.

  • Sentence A: Who is going to the party?
  • Sentence B: Whom should I invite to the party?

In sentence A, you could answer with a person’s name, or with a subject pronoun like she or he. The people are the subject of the sentence.

But in sentence B, whom is the object of the verb invite, and you would answer with an object pronoun like him or her.

Subject vs object pronouns

Let’s check out another example of how to turn a sentence into a question with the word whom:

  • Tony ate the sandwich.

In this sentence, Tony is doing something; he’s eating. That means he’s the subject of the sentence. You could replace Tony’s name with who to form a question:

  • Who ate the sandwich?

If we wanted to use whom, we can flip the original sentence and make the sandwich the subject and Tony the object.

  • The sandwich was eaten by Tony.

Now the subject of the sentence (the sandwich) is not performing the action. The sandwich isn’t the one doing the eating! We could replace Tony with whom to ask the question:

  • By whom was the sandwich eaten?

When to Use Who (Examples in a Sentence)

Not sure if you should use who? Don’t worry; there’s a simple trick to help. All you have to do is see if you could answer the question you’re posing with he or she or they. If you could, then who is correct.

Which of these sentences is correct?

  • Sentence A: Who ate my snack?
  • Sentence B: Whom ate my snack?

Try answering this question by adding she or he in the answer:

  • She ate my snack.

Because you can use she, sentence A is correct: Who ate my snack?

Who used in a sentence

Here are some other example sentences with who:

  • Who else wants cake?
  • My mother, who immigrated from Chile in the 1980s, has always loved American culture.
  • A child who is hungry can’t learn properly.

When to Use Whom (Examples in a Sentence)

So what about when to use whom? Just like in the example above, try answering your own question. If you have to use him or her or them in your reply, you’ll need to use whom.

Which of these sentences is correct?

  • Sentence A: To who is the package being sent?
  • Sentence B: To whom is the package being sent?

You can only reply to this question by using him, her, or them:

  • The package is being sent to him.

Whom in a sentence

That makes the correct answer sentence B: To whom is the package being sent?

Here are some more examples of whom in a sentence:

  • Whom are you supporting in the election?
  • Whom should I contact about the party?
  • Whom do you want to ask to the dance?

Another useful tip is to remember that whom is always used instead of who after the prepositions to, for, with, and of. Here are some examples of whom after a preposition:

  • The employee, with whom I spoke, said I could have a refund.
  • The children, one of whom dislikes loud noises, will be with us all weekend.
  • For whom should I wait?

Many native English speakers don’t use whom at all, thinking it sounds old-fashioned and pretentious. Instead, they will use who for both the subject and object of a sentence. This isn’t correct, but most native English readers won’t notice the error.

If you’re having a conversation with someone, you may spot them using who rather than whom. While this is fine when speaking, it’s always best to use the correct form in writing, especially in professional settings.

On the flipside, some English speakers use whom instead of who in an attempt to sound sophisticated or formal. This is something to avoid, especially in legal and academic writing where this mistake will be obvious. Often, using whom in error to sound intelligent backfires and makes you sound less educated.
