From Middle English proven, from Old English prōfian (“to esteem, regard as, evince, try, prove”) and Old French prover (“to prove”), both from Latin probō (“test, try, examine, approve, show to be good or fit, prove”, verb), from probus (“good, worthy, excellent”), from Proto-Indo-European *pro-bʰuH-s (“being in front, prominent”), from *pro-, *per- (“toward”) + *bʰuH- (“to be”). Displaced native Middle English sothen (“to prove”), from Old English sōþian (“to prove”). Doublet of probe. More at for, be, soothe.
