Who & Whom

Information:
subject pronouns - I, he, she, they, we, who
object pronouns - me, him, her, them, us, whom

Rule:
1) Use "who" if it is the subject of the sentence.
a) ex: "Who is the smartest person in the world?"
2) Use "whom" if it is the object of the sentence.
a) ex: "You are going to the concert with whom?"
3) Hint - if you don't know which one to use, insert another fitting subject or object pronoun
to see if the sentence still makes sense
a) ex: "You are going to the concert with (him)?" - right
b) ex: "You are going to the concert with (he)?" - wrong

Exceptions/Special rules:
1) In situations where "who/whom" would be both an object and a subject, use "who," the subject form.
a) ex: "I'll go to the concert with whoever is a lover of heavy metal."
2) When "who/whom" follows some form of "to be," use the subject form.
a) ex: "I am who high-fived the orangutan"
