"Pour tu" isn't correct, you must use "Pour toi".
"Pour tu" isn't correct?
Hope this helps :)
"Pour toi, pour eux" isnt correct?
Why is the polite form "vous" not accepted?
Why isn't l'enfants okay?
is "à toi, à les enfants." considered correct?
I keep writing the correct response like you have listed and it won't accept it.
