EtymologyEdit

From French groupe (cluster, group), from Italian gruppo groppo (a knot, heap, group, bag (of money)), itself derived from Vulgar Latin *kruppo, from Proto-Germanic *kruppaz (lump, round mass, body, crop), from Proto-Indo-European *grewb- (to crumple, bend, crawl). Cognate with German Kropf (crop, craw, bunch), Old English cropp, croppa (cluster, bunch, sprout, flower, berry, ear of corn, crop), Dutch krop (craw), Old Norse kroppr (hump, bunch). More at crop, croup.
