swike

Etymology

Came into English via Middle English swiken, from Old English swīcan ("to wander, depart, cease from, yield, give way, fail, fall short, be wanting, abandon, desert, turn traitor, deceive, rebel"), from Proto-West Germanic *swīkwan, from Proto-Germanic *swīkwaną ("to dodge, swerve, avoid, betray"), ultimately from Proto-Indo-European *sweyg- ("to turn, move around, wander, swing").
