From school and from the school implies the same in English, thus both should be accepted.
I feel a difference between I leave the school and I leave school. When I leave the school, I go out of the buildung and go home. If I leave school, I stop learning there forever.
Is it right?
Maybe I can use the same story for I go away from the school./ I go away from school.
I would say, if I leave school, i stop studying not only there, but altogether?
Great. The English and Hungarian meaning can have some very drastic differences with article or not and el- usually adds completeness. But forever or for today is not clear too.
Does this mean that I leave school, having finished my education at the age of 18, or just that I leave the building at tge end of the day? Or both?
