Morphology

undo = do (transparent) = un + do

Simple, productive negative prefix 'un-' applied to the common verb 'do' meaning to reverse or cancel an action, which is directly inferable.

Etymology

Undo comes from the old prefix un- meaning 'reverse' and the verb do, so it originally meant to 'reverse what was done'. That's why to undo something today is to cancel or reverse its effect.
