What does undoing mean?
Undoing is both a present-participle form of undo and a noun naming its action. In contemporary use, it commonly denotes reversal or cancellation, as in undoing a mistaken decision or repairing the consequences of earlier work. As a noun, it can refer to the process of reversing something, especially a decision, rule, or effect. The word is also used for a more dramatic and literary fate: ruin, downfall, or defeat. That sense often appears in expressions suggesting that a reversal is impossible. When used as a gerund, undoing usually takes a direct object and describes an action in progress; when used as a noun, it names the action or its result. Undoing is neutral in register in its reversal sense, while the ruin sense is more elevated and dramatic. Its usefulness lies in its ability to name both deliberate correction and the potentially final collapse of someone's prospects.
