Rules to Remember


RULE: Use who as the subject of a sentence.
Who are you? Who sent you?

RULE: Use whom as the object of a sentence or the object of a preposition.
That is whom I saw.
Whom are you referring to?
Whom did you say the book was about?

Whom as the object of a preposition:
in whom
to whom
for whom
about whom
over whom
from whom

WARNING: Using whom instead of whom is sometimes considered as hyper-correct. For example, many native speakers refer to use who even when it is the object of a preposition. They will say, "It a all depends on who (whom ) you ask " and "Who (whom) did you vote for?
