Who vs Whom Subject and Object Pronouns

Learn how to correctly use 'who' and 'whom' to enhance clarity and professionalism in your writing and speaking.

Who vs Whom helps you distinguish between subjects and objects in a sentence, enhancing clarity and precision. This lesson will guide you in using these pronouns correctly in various contexts.

Examples

Example 1

Incorrect Whom is going to the meeting?

Better Who is going to the meeting?

'Who' is the correct choice because it is the subject of the verb 'is going'.

Example 2

Incorrect Who did you speak with?

Better Whom did you speak with?

'Whom' is correct here because it is the object of the preposition 'with'.

How It Works

Meaning

'Who' and 'whom' are pronouns used to refer to people. 'Who' is used as a subject, while 'whom' is used as an object in a sentence.

Understanding the difference helps in crafting grammatically correct sentences, especially in formal writing and speech.

At the B2 level, mastering 'who' and 'whom' enhances clarity and professionalism in communication.

Use it when

  • Using 'who' as the subject of a verb (e.g., "Who is coming?").
  • Using 'whom' as the object of a verb or preposition (e.g., "To whom should I send this?").
  • Formulating questions or relative clauses that require precision in formal contexts.

See it

Who is responsible for this project?
The person whom you met yesterday is my colleague.

Quick rules

  • Use 'who' when referring to the subject of a clause.
  • Use 'whom' when referring to the object of a verb or preposition.
  • In formal writing, always ensure the correct use of 'who' and 'whom' to maintain clarity.
  • Remember: 'who' = subject, 'whom' = object.
