What does irrevocably mean?
Irrevocably means that something cannot be changed, undone, or reversed. It describes decisions, commitments, losses, changes, and other developments that have become permanent. The word is especially common in formal writing and public statements, where it stresses finality: a country may become irrevocably committed to a policy, or a decision may be described as irrevocably made. Because the word conveys absolute permanence, it should be used carefully when a situation is only difficult or unlikely to reverse, rather than genuinely impossible. Its related adjective is “irrevocable,” and the closely related adverb “irreversibly” is often used in similar contexts.

Where does irrevocably come from?
The word comes from the Latin prefix meaning “not” and the Latin verb revocare, meaning “to call back” or “to revoke.” The adjective “irrevocable” developed from this root and was already in English by the late 16th century. The adverb “irrevocably” was formed from that adjective, with the standard English suffix “-ly.” Related English words include “revoke,” “revocable,” and “revocation.”
