Who vs Whom: Understanding Usage with Clear Examples

  • Who” serves as the subject pronoun, while “whom” functions as the object pronoun.
  • A simple heuristic to distinguish between them is substituting “who” with “he” or “she,” and “whom” with “him” or “her.”
  • Properly using “who” and “whom” enhances the precision and formality of written language.

Navigating the intricacies of English grammar can often seem daunting, especially when it comes to choosing between the pronouns “who” and “whom.” These terms are frequently misused, although they serve distinct purposes within sentences. “Who” is used when referring to the subject of a sentence—the person performing the action—whereas “whom” is reserved for the object, the individual on the receiving end of the action.

Who’s vs Whom: Understanding the Difference

Who’s is a contraction for “who is” or “who has,” and is never to be confused with whom, which is an objective case pronoun used to refer to the object of a verb or preposition.

Examples of “who’s”:

  • Who’s going to the store? (“who’s” = “who is”)
  • I wonder who’s seen my keys. (“who’s” = “who has”)

Whom, on the other hand, plays a different role; it’s used to refer to someone who is the recipient of an action or is being described in relation to something else.

When to Use “Who”When to Use “Whom”
As the subject of a clauseAs the object of a clause
Alongside subjects like “He” or “She”Alongside objects like “Him” or “Her”

To test: If you can replace it with “he” or “she,” use who. If “him” or “her” fits better, use whom.

Examples with “whom”:

  • The author, whom you met last week, is signing books today.
  • Whom did you give the book to?
  • Use who when referring to the subject.
  • Use whom when referring to the object of an action or preposition.

Exploring Relative Pronouns: A Quick Overview

Who is used primarily as a subjective pronoun, meaning it refers to the subject of the verb, the one doing the action. For example:

  • The journalist who wrote the article won an award.

Conversely, whom serves as an objective pronoun, relating to the object of a verb or preposition. For instance:

  • To whom did you give the book?
Subjective PronounExample Sentence
WhoShe is the one who loves to travel.
Objective PronounExample Sentence
WhomHe is the one whom the company greatly values.

Consider these scenarios:

  • Who/Whom is calling me? (Rephrased: Is he calling me? Use who.)
  • You met who/whom at the party? (Rephrased: You met him at the party? Use whom.)
