G3-b Use who as a subject and whom as an object.

object The part of a clause that receives the action of the verb, or the part of a phrase that follows a preposition.

preposition A word (such as between, in, or of) that indicates the relation between a word in a sentence and its object.

Two strategies can help you figure out whether to use who or whom.

  1. Arrange the phrase’s or clause’s words in subject-verb-object order or preposition-object order. In this standard order, a subject (who) is followed by a verb, but an object (whom) follows a subject and verb or a preposition.
  2. Look for the subject of the clause. If the verb in the clause has another subject, use whom; if the verb in the clause has no other subject, use who. If it is the object of a preposition, use whom.
