'Who' vs 'Whom': Differences, Examples, and When to Use

By Shanea Patterson, updated on March 14, 2023

‘Who’ and ‘Whom’ are words that often get confused with one another, but what’s the difference? And what do they each mean? We’ll go over that in this article, plus teach you how to use both in a sentence.

In short, the difference is:

  • ‘Who’ is a subject that performs the action in a sentence.
  • ‘Whom’ functions more like an object, and it’s used when it’s receiving the action.

These words are often incorrectly used interchangeably. But they have slightly different usages, so avoid using them interchangeably.

How and When to Use ‘Who’ and ‘Whom’

The word ‘who’ is a pronoun, similar to ‘I’ or ‘he.’ ‘Who’ is usually the subject of a sentence, while ‘whom’ is the object.

  • For example, if someone says, ‘Who did this?’ Someone might reply, ‘He did this.’

‘Whom’ can also be used after prepositions.

For example, when someone addresses another person they don’t know in a letter, you might see:

‘To Whom It May Concern.’

The Difference Between ‘Who’ and ‘Whom’ 

As you’ve seen, the difference between ‘who’ and ‘whom’ is slight.

‘Who’ is the subject performing the action in a sentence, while ‘whom’ is the object receiving the action.

For example, you might hear someone say:

‘We don’t know who has been vandalizing the church.’

In this case, the subject is the person ‘who’ has been vandalizing the church.

Another example of something you might hear someone say is:

‘We don’t know whom this story is about. Let’s not speculate.’

In this case, the subject isn’t the ‘whom’ but the ‘we’ because the ‘we’ is the one doing the ‘not-knowing.’

Definition of ‘Who’: What Does ‘Who’ Mean?

The Merriam-Webster dictionary defines ‘who’ as:

  • What or which person or persons (used as an interrogative).

It also means:

  • Used by speakers on all educational levels and by many reputable writers, though disapproved by some grammarians, as the object of a verb or a following preposition
  • The person or persons that (whoever)
  • Used as a function word to introduce a relative clause (used especially in reference to persons)
  • In reference to groups
  • In reference to animals
  • In reference to inanimate objects, especially with the implication that the reference is really to a person

Definition of ‘Whom’: What Does ‘Whom’ Mean?

The same dictionary defines ‘whom’ as:

  • Used as an interrogative or relative (as an object of a verb or a preceding preposition).

It could also mean:

  • Of less frequently as the object of a following preposition
  • Often considered stilted, especially as an interrogative and especially in oral use

  • My sister absolutely hates to fly, but her husband lives overseas, so she flies all the time now. I guess she’s gotten used to it.
  • I wasn’t sure who would be there, but I decided to go anyway. Maybe Stacy will show up, and I’ll actually have someone to talk to.
  • I used to love that song by Xscape, ‘Who Can I Run To?’ That’s one classic 90s R&B hit I can listen to over and over again to this day.
  • Who has been in my room? I know someone’s been in here because a few things have been moved around. Someone better starts answering me soon, or everyone’s getting in trouble!
