- prove:  The ultimate source of prove was Latin probus ‘good’. This went back (like the related Sanskrit prabhu- ‘eminent, mighty’) to a prehistoric Indo-European compound *probhwo- ‘being in front’, hence ‘excelling’ (*promeant ‘in front’, and *bhwo- was the ancestor of English be). From it was derived the verb probāre ‘test, approve, prove’, which has given English approve, probable, probe, proof, reprobate, reprove, and of course prove, acquired via Old French prover. Another Latin derivative of probus was probitās ‘honesty’, from which English gets probity .
=> approve, probable, probe, proof, reprobate

- late 12c., pruven, proven "to try, test; evaluate; demonstrate," from Old French prover, pruver "show; convince; put to the test" (11c., Modern French prouver), from Latin probare "to make good; esteem, represent as good; make credible, show, demonstrate; test, inspect; judge by trial" (source also of Spanish probar, Italian probare), from probus "worthy, good, upright, virtuous," from PIE *pro-bhwo- "being in front," from *pro-, extended form of root *per- (1) "forward, through" (see per), + root *bhu- "to be" (cognates: Latin fui "I have been," futurus "about to be;" Old English beon "to be;" see be).
