What does irrevocable mean?
Irrevocable describes something that cannot be revoked, withdrawn, cancelled, or changed once it has been established. The word is especially common in legal and political language, where it marks decisions, commitments, refusals, and official acts as final and beyond reversal. It may also describe broader situations that cannot practically be undone, such as a career decision or a personal choice with lasting consequences. Unlike simply saying that something is permanent, irrevocable focuses on the impossibility of calling it back or reversing it. The term is typically formal, and using it often emphasizes the seriousness or finality of the matter. Its familiar counterpart is revocable, meaning that something can be cancelled or withdrawn. Irrevocable is also useful where the consequences of an action matter as much as the action itself: the word captures not only a decision having been made, but the closing of the possibility that it will later be undone.
