Who vs Whom

We already know that there is a difference between these two pronouns, but don’t exactly know what it is.

“Who” refers to the subject of the sentence. On the other hand, “whom” refers to the object of a verb or preposition.

When to Use Who & Whom

One helpful tip to distinguish between the two is to replace it with another pronoun. If you can replace “he” or “she” with it, use “who” in your sentence. Meanwhile, use “whom” if you can replace it with “him” or “her” with it.

Who vs Whom Examples

To make things easier, here are some examples to help you distinguish between the two pronouns.

Who/whom will pay for the meal?

Right: Who will pay for the meal?
Wrong: Whom will pay for the meal?

This example makes more sense when you read, “he/she will pay for the meal.” It doesn’t make sense if you used him/her. This is why using who is the right answer.

The package is delivered to the house by who/whom?

Right: The package is delivered to the house by whom?
Wrong: The package is delivered to the house by who?

It gets tricky because they both sound right. Remember, first identify what’s the subject of the sentence. In this case, the subject is the package and not the person doing it. Which is why we use “whom” in this sentence because it is the object of the verb “delivered.”

Let’s use the helpful tip of replacing pronouns again. The sentence “The package is delivered to the house by him/her” makes more sense than using “he/she.”

Who/Whom is being summoned to court?

Right: Who is being summoned to court?
Wrong: Whom is being summoned to court?

In this example, it makes more sense to read, “He/She is being summoned to court” compared to “him/her.”

How To Avoid The Who Vs Whom Error

You may not realize this, but there are certain types of sentences in which you will want to use whom rather than who. These words are similar to each other in appearance, but they differ in meaning. One of the biggest differences between the two is that who looks like the subject of the first verb, whereas whom looks like the object of the second verb. Subjects are more important than objects, as they speak louder than the objects and propel the action in a sentence.

The first problem with using whom in place of whom is that the words may sound strange. However, learning to use whom correctly will make your writing better. Although this error may seem inconsequential, getting the difference right can help you sound more educated and sophisticated. You can use the grammar checker on sites like Grammarly to ensure your writing is error-free.

Another way to avoid the who vs whom error is to remember that whom is used for the object of a sentence. While it is more common to use whom than who, it is still important to remember that both words have different meanings. While “who” is used when you want to refer to the subject of a sentence, “whom” is used when you want to refer to something specific.

Another way to avoid the who vs whom error is to use the second who in a clause that has a second who as the subject. This is because the first who must be the object of the first clause. Using a visual approach is also helpful. Visualizing your sentence will help you make the correct choice when using the subject-object pronouns.

Who vs Whom vs Whose

“Whose” is the possessive form of “who.” This means that you should only use this for sentences that indicate possession. This is often used in questions.

Whose dog is this?
Whose car is parked outside?
Whose turn is it to go outside?
