The pronoun who usually refers only to persons.

its form depending on the case, as shown in the
following table.
• Subjective Case: who
• Objective Case: whom
• Possessive Case: whose

4. WHO OR WHOM?
• Choose the correct form of who based on the function of the
word in the sentence.
Who…subjective case Whom…objective case
To (who, whom) does the keychain belong?
To is a preposition; the noun or pronoun that ends a
prepositional phrase is called the object of the preposition.

case is whom.

who=predicate nominative)

expressed by the sentence: To whom do these books
belong?
