Morphology

overpressure = pressure (transparent) = over + pressure

The meaning is directly derived from 'over' (excess) + 'pressure' and is understandable to learners who know those parts.

Etymology

The word overpressure is made of over- meaning 'above' and pressure meaning a 'push' or strong force. So overpressure is simply an extra push of air 'above' the normal level, which is why we use it for a sudden rise in air pressure after an explosion or shock wave.
