Nguồn gốc và lịch sử

Etymology tree Proto-Indo-European *grewbʰ-der. Proto-Germanic *kruppazder. Frankish *kruppbor. Vulgar Latin *cruppus Italian gruppobor. French groupebor. ▲ Italian gruppobor. English group From French groupe (“cluster, group”), from Italian gruppo, groppo (“a knot, heap, group, bag (of money)”). Displaced native Old English hād (“tribe, group”). In the "group theory" sense, calqued from French groupe, a term coined by the young French mathematician Évariste Galois in 1830. Cognate with German Kropf (“crop, craw, bunch”); Old English cropp, croppa (“cluster, bunch, sprout, flower, berry, ear of corn, crop”) (whence English crop); Dutch krop (“craw”), Icelandic kroppr (“hump, bunch”). Doublet of crop and croup. Compare Persian گروه.
