reprobate: [16] The Latin prefix re- usually denoted ‘return’ or ‘repetition’, but it was also used for ‘reversal of a previous condition’. This usage lies behind Latin reprobāre (source of English reprove [14]), a compound verb based on probāre ‘test, approve’ (source of English prove). It meant ‘disapprove’, and its past participle reprobātus was used in post-classical Latin to denote a person ‘disapproved or abandoned by God’ because of their wickedness.
