undo

This word carries a strong sense of reversal, whether physical or abstract. When applied to fasteners, it describes the mechanical act of releasing a tension or lock. In a digital or administrative context, it implies a perfect restoration of a previous state, as if the intervening action never occurred. When used in reference to a person's fate, the word takes on a darker, more inevitable tone. It suggests a process of unraveling where a specific flaw or mistake leads to total collapse, mirroring the way a knitted fabric falls apart when a single thread is pulled.
