Etymology 1

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.

Etymology 2

Simple past form of proove, conjugated as a Germanic strong verb, on the pattern of choose → chose.
