Pronoun case: I or me, who or whom
Use I, he, she, we, they and who as subjects; use me, him, her, us, them and whom as objects.
Updated October 29, 2026
The rule
After a preposition (between, with, for, to) or as the object of a verb, use the object form: between you and me, for him and her.
Who does the action; whom receives it. If you could answer with "him", use whom; if "he", use who.
Examples
Mom made pancakes for my sister and I.Mom made pancakes for my sister and me.Whom is coming to the party?Who is coming to the party?
Quick test: Drop the other person: "for my sister and I" becomes "for I", which sounds wrong, so it is "for me".

Dad took my brother and me to the park.
Took ... me: drop "my brother and" and you would never say "took I".
Me and Sam built a fort.
Sam and I built a fort.
The pair is the subject, so use I. It is polite to name the other person first.
This secret is just between you and I.
This secret is just between you and me.
Between is a preposition, so it takes the object form: between you and me.
The prize went to whomever finished first.
The prize went to whoever finished first.
The word is the subject of "finished", so it takes the subject form, whoever.
