precaution

Definitions

pre- (before) + caut (from cavēre 'to beware') + -ion (act of) = 'the act of taking care beforehand.' The defining idea is timing: a precaution is caution applied in advance, so trouble never arrives in the first place — backing up files, wearing a seatbelt, locking the door.
