once and for all

Finally and definitively, so the matter is settled permanently and won’t need to be dealt with again.

Recorded from Middle English; it combines “once” (one time) with “for all” (for everyone/for good) to stress that something is done decisively and permanently.

Used to emphasize a permanent, decisive resolution (often in arguments, rules, or misunderstandings). Can sound firm or impatient, especially in commands.
