who and whom

Who and whoever, subjective-case pronouns, are used for subjects and subject complements. Whom and whomever, objective-case pronouns, are used for objects.

The choice between who and whom (or whoever and whomever) occurs primarily in subordinate clauses and in questions.

Example sentence: Daniel always volunteers this information to whoever will listen.

Whoever is required as the subject of the verb will listen.

When the pronoun functions as the subject of an infinitive, use whom or whomever.

Example sentence: My cousin Sylvie, whom I am teaching to fly a kite, watches us every time we compete.

Whom is required as the subject of the infinitive phrase to fly a kite. See subjects and objects of infinitives.
