O.E. wincian "to nod, wink," from P.Gmc. *wenkanan (cf. Du. wenken, O.H.G. winkan, Ger. winken), a gradational variant of the root of O.H.G. wankon "to stagger, totter," O.N. vakka "to stray, hover," from PIE *weng- "to bend, curve." The meaning "close an eye as a hint or signal" is first recorded c.1100; that of "close one's eyes to fault or irregularity" first attested c.1480. The noun is recorded from c.1300; meaning "very brief moment of time" is attested from 1585.
