Morphology

drop + off

The meaning 'to fall from a position' is directly and compositionally derived from 'drop' (to fall or let fall) plus 'off' (away from a surface/place). This is a common, literal verb+particle spatial construction found across languages, so a B1 learner who knows the constituents will readily infer the MWE meaning.

Etymology

Drop off The phrasal verb drop off describes how a person's head or body seems to fall when they sleep; drop and off give the picture of dropping away, like your head nodding on the sofa. So, it means 'to fall asleep'.
