Latin edit

Etymology edit

From Proto-Italic *-plos, cognate with Ancient Greek -πλόος (-plóos) or -πλός (-plós) (as in διπλός (diplós)), the second element of Old Irish díabul (double)[1] and possibly Proto-Germanic *twīflaz (doubt). From an unclear root of the form *pl(H), possibly from Proto-Indo-European *pleh₁- (to fill) or Proto-Indo-European *pelh₂- (to approach)[1] or Proto-Indo-European *pel- (to fold), source of Proto-Germanic *-falþaz (-fold).[2] Compare also -plex.
