Origin of Proven

  • From Scottish English, as past participle of preve, a Middle English variant of prove - compare woven (from weave) and cloven (from cleave), both of which feature -eve-oven. preve died out in England, but survived in Scotland, where proven developed, initially in a legal context, as in “The jury ruled that the charges were not proven." See usage notes for historical usage patterns.

    From Wiktionary

  • Earlier, from Late Latin probō (“test, try, examine, approve, show to be good or fit, prove", verb), from probus (“good, worthy, excellent"), from Proto-Indo-European *pro-bhwo- (“being in front, prominent"), from Proto-Indo-European *pro-, *per- (“toward") + Proto-Indo-European *bhu- (“to be").
