Word History

Etymology

Verb

Middle English defien "to renounce, disavow, scorn, challenge to fight," borrowed from Anglo-French defier, desfier, from de-, des- de- + fier "to pledge, trust in, rely on," going back to Vulgar Latin *fīdāre, re-formation of Latin fīdere "to trust (in), have confidence (in)" — more at faith entry 1

Note: The sense history was perhaps "to break faith with" > "to scorn" > "to challenge to a fight," though the latter meaning appears to be the earliest in Old French.

Noun

in part borrowed from Middle French deffy, noun derivative of defier "to challenge, defy entry 1," in part derivative of defy entry 1
