Who and whom

Who Definition vs Whom Definition

• WHO is a pronoun that refers to the subject of the sentence.
• WHOM is a pronoun that refers to the object of the sentence.

Examples:

• Who locked the door?
• She’s the woman whom I met in Paris.

1) You are asking about the subject, i.e. the person who performs the action, e.g. Who is his mother? Who will come here tomorrow?

2) You are adding a clause to give additional information about the subject, e.g. Jennifer is my friend who likes reading.

3) You are asking about the name of someone or a group of people, e.g. Who is the class president?

When to Use Whom

1) You are asking about the object, i.e. the person to which the action is directed, e.g. Whom should I help? Whom did you ask to come with you?

2) You are adding a relative clause to give additional information about the object, e.g. She called the man whom she met yesterday.

3) You are asking an indirect question about the object, e.g. They asked me, whom I invited to dinner.
