irrevocable

the word 'irrevocable' is built from latin components. the core is the verb 'revocare', meaning 'to call back', itself formed from 're-' (back) and 'vocare' (to call). the suffix '-abilis' was added to create the adjective 'revocabilis', meaning 'capable of being called back'. the negative prefix 'in-' (which assimilates to 'ir-' before 'r') was then applied, forming 'irrevocabilis', literally 'not capable of being called back'. this legal and formal term entered english via old french, retaining its sense of something that cannot be undone, repealed, or altered, conveying a sense of absolute finality.

Structure: ir (not) + revoc (call) + able (capable of) - ir: latin origin, a variant of the prefix 'in-' meaning 'not'. - revoc: from latin 'revocare', meaning 'to call back' or 'to recall'. the root 'voc' means 'to call'. - able: from latin suffix '-abilis', meaning 'capable of, fit for'.
