Peasants using flails (tool) to thresh cereal.
a flail (weapon)


From Middle English flaile, flayle, from earlier Middle English fleil, fleyl, fleȝȝl, flegl, from Old English fligel, *flegel ‎(flail), from Proto-Germanic *flagilaz ‎(flail, whip), of uncertain origin. Cognate with Scots flail ‎(a thresher's flail), West Frisian fleil, flaaiel ‎(flail), Dutch vlegel ‎(flail), Low German vlegel ‎(flail), German Flegel ‎(flail). Possibly a native Germanic form from Proto-Germanic *flag-, *flah- ‎(to whip, beat), from Proto-Indo-European *plak-, *plāk- ("to beat, hit, strike; weep"; compare Lithuanian plàkti ‎(to whip, lash, flog), Ancient Greek πληγνύναι ‎(plēgnúnai, strike, hit, encounter), Latin plangō ‎(lament", i.e. "beat one's breast)) + Proto-Germanic *-ilaz ‎(instrumental suffix); or a borrowing of Latin flagellum, diminutive of flagrum ‎(scourge, whip), from Proto-Indo-European *bʰlag-, *bʰlaǵ- ("to beat"; compare Old Norse blekkja ‎(to beat, mistreat)). Compare also Old French flael ‎(flail), Walloon flayea ‎(flail) (locally pronounced "flai"), Italian flagello ‎(scourge, whip, plague).
