History
Etymology
From Middle English flap, flappe (“a slap; blow; buffet; fly-flap; something flexible or loose; flap”), related to Saterland Frisian Flappert (“wing, flipper”), Middle Dutch flabbe (“a blow; slap on the face; fly-flap; flap”) (modern Dutch flap (“flap”)), Middle Low German flabbe, vlabbe, flebbe, from the verb (see below). Related also to English flab and flabby.
From Middle English flappen (“to flap, clap, slap, strike”), related to Dutch flappen (“to flap”), German Low German flappen (“to flap”), German flappen (“to flap”), Dutch flabberen (“to flit, flap”). Probably ultimately imitative.
