over and above ? favorite Is is possible to say that "Above" means "over" and "Under" means"below", but not the opposite?According to my grammar:Over - In a higher position (close or touching) Above - In a higher positionUnder - In a lower position (close or touching) Below - In a lower positionExample: There's a helicopter flying round above / over the school.I would interpret this sentence as "above" meaning almost touching the school or not. And If I hear "over", the helicopter is almost touching school.This makes me think about "over" and "on". "On" means that something is touching something, but if "over" can mean also "touch".Well, I would never use "over" to mean "touching something", I would use "on" instead.Do you have a language question?

please i wanna know the difference between may i , could i and shall i ?? thanks a lot ..
