When should I use who and whom?

Use who as a subject pronoun (e.g., “I,” “he,” “she,” “they”) and whom as an object pronoun (e.g., “me, “him,” “her,” “them”).

For example, “Is Ellie the friend who gave you the tickets?” could be recast as “Yes, she gave me the tickets.”

Conversely, “Is Ellie the friend whom you gave the tickets to?” could be recast as “Yes, I gave the tickets to her.”
