Morphology

overnight = night (semi-transparent) = over + night

The suddenness meaning 'very quickly' is a metaphorical extension from 'during the night' and is not strictly literal. [Postprocessing: moved 'over' from base_words to prefix]

Etymology

Overnight A helpful way to remember the 'very quickly' sense of overnight is to think of something changing 'over the night' so it is new by morning; that's why we say something happened 'overnight' when it changed very fast.
