On a language-exchange app I use, a non-native speaker said (emphasis mine):
When you are absolutely sick and tired of exams and everything you want is to listen to music
One person corrected everything to all, and the non-native asked why they made the change. I’ve tried googling the answer for a while now, and read up a little on pronouns and determiners, but I still don’t know how to explain it.
So my question is: How do you explain why you’re supposed to use all instead of everything here?
