Synonym discussion

Sense: adverb/1

All four adverbs describe outcomes that last, but each carries a different emphasis. Irrevocably stresses that nothing can undo the result — the cause is final because the change itself cannot be reversed. Irreversibly overlaps in meaning but is far more common in scientific or technical writing (irreversibly damaged tissue, an irreversible chemical reaction). Permanently describes a state that continues indefinitely without necessarily implying that change was once possible — a sign can stand permanently without ever having been different. Inevitably means unavoidably, not unchangeably: an outcome that was certain to happen. Definitively focuses on conclusiveness of proof or settlement (the question was settled definitively), leaving open the possibility that new evidence could later overturn it. For example, a court that irrevocably separates twins is issuing a decision that cannot be undone; a theory that is definitively disproved may still be revived.

Etymology

LatinEnglish

Comes from Latin irrevocabilis, formed from the prefix in- (not) and revocare (to call back, recall). The idea of something that 'cannot be called back' entered English in the late 1500s, at first used for legal and formal decisions, later extended to any permanent change.
