The Basics: Subject vs. Object

At the core of the “who” versus “whom” debate lies a simple concept: subject versus object.

• Who is used when referring to the subject of a sentence—the person performing the action.

• Whom is used when referring to the object—the person receiving the action.

That’s it! But let’s break it down a little further for clarity.

When to Use “Who”

“Who” performs the action in a sentence. It’s a pronoun that stands in for a subject. If you can replace “who” with a subject pronoun like “he,” “she,” or “they,” you’re on the right track.

Examples:

Who is going to the party? (He is going to the party.)

Who made this delicious cake? (She made this delicious cake.)

In both examples, “who” refers to the person performing the action: going to the party or making the cake.

When to Use “Whom”

“Whom” receives the action in a sentence. It acts as the object of a verb or preposition. If you can replace “whom” with object pronouns like “him,” “her,” or “them,” you’ve got it right.

Examples:

Whom did you invite to the party? (I invited him to the party.)

To whom should I address the letter? (You should address the letter to her.)

Here, “whom” refers to the person receiving the action: being invited or receiving the letter.

A Simple Trick to Remember

Still confused? Try this little trick:

• Rewrite the sentence using “he/him” or “she/her.”

  • If “he” or “she” fits, use who.

  • If “him” or “her” fits, use whom.

Let’s test it out:

• (Who/Whom) should I call?

  • Rewrite: “Should I call him?”

  • Since “him” fits, you know the correct choice is whom.

• (Who/Whom) is at the door?

  • Rewrite: “He is at the door.”

  • Since “he” fits, the correct choice is who.

Common Misconceptions and Pitfalls

One of the most common mistakes people make is defaulting to “who” in formal writing because “whom” sounds overly formal or outdated. While it’s true that “whom” can feel stiff in casual conversation, it still plays a vital role in polished, professional communication. Let’s address a few common pitfalls:

1. Ending Sentences with Prepositions

When a sentence ends with a preposition, the correct choice is usually “whom, because prepositions require objects.

Incorrect: Who should I send this email to?

Correct: Whom should I send this email to?

2. Questions That Begin with Prepositions

If a question begins with a preposition, “whom” will often follow it. Prepositions take objects, and since “whom” is the object pronoun, it’s the right choice.

Examples:

• To whom did you give the book?

• For whom was the package intended?

3. Relative Clauses

When using “who” or “whom” to introduce a relative clause, apply the subject-object rule again. If the clause describes someone doing something, use “who.” If it describes someone to whom something is done, use “whom.”

Examples:

The manager, who leads the team, is excellent. (Subject: The manager leads the team.)

The colleague whom you recommended got the job. (Object: You recommended the colleague.)

Breaking the Rules?

Language evolves, and so do grammar rules. Many modern speakers opt for “who” in everyday conversation regardless of whether it’s technically correct and generally acceptable in informal settings. However, when you’re writing professionally or need to make a polished impression, using “whom” correctly still matters

It’s similar to the difference between wearing sweatpants at home and a suit to a business meeting. In casual environments, you can relax the rules, but in more formal situations, it’s best to stick to the standard.

Wrapping It Up: Your Grammar Toolkit

Mastering “who” and “whom” is like having a secret weapon for clear, concise, and professional communication. Remember:

• Use who for subjects—the ones doing the action.

• Use whom for objects—the ones receiving the action.

And don’t forget the handy “he/him” trick to guide you when in doubt. With these simple guidelines, you’ll never mix up “who” and “whom” again! Now, go forth and write confidently, knowing you’ve got this grammar challenge under control!
