Etymology

1553, from the merger of Early Modern English flirt (“to flick”), flurt (“to mock, jibe, scorn”), and flirt, flurt (“a giddy girl”). Of obscure origin and relation. Apparently related to similar words in Germanic, all of apparently onomatopoeic origin, compare Low German flirt (“a flick of the fingers, a light blow”), Low German flirtje (“a giddy girl”), Low German flirtje (“a flirt”), German Flittchen (“a flirt; tart; hussy”), Norwegian flira (“to giggle, titter”). Compare also Early Modern English jillflirt, gillian flirt, and flirt-gill (“a flirt”), and Scots flird (“a trifling", also, "to jibe, jeer at, talk idly, flirt, flaunt”), which is perhaps from Middle English flerd (“mockery, fraud, deception”), from Old English fleard (“nonsense, vanity, folly, deception”); potentially related to Icelandic flærð (“trickiness, deceit”), Swedish flärd (“vanity, frivolity, flamboyance”), Dutch flard (“tatter, shred”). See flird.
