Morphology

undoing = undo (semi-transparent) = un + do + ing

Morphologically 'undo' + '-ing', but the sense 'cause of failure or ruin' is an idiomatic/metaphorical extension not directly deducible from the base.

Etymology

Undoing comes from un- 'reverse' and do 'to act'. It can mean an 'unmaking' that causes failure or ruin, which is why we say someone's pride was their undoing.
