(third-person singular simple present flails, present participle flailing, simple past and past participle flailed)
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 (plēgnýnai, “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”), Italian flagello (“scourge, whip, plague”).
