Pronunciation

Forms

défi m (plural défis)[1]

Etymology

It is a deverbal noun from French défier,[2][1][3] a verb formed from dé- and fier1 “to trust”,[3][4] which comes from Vulgar Latin *fīdō (“to entrust”), derived from fīdus (“faithful”).[4][5] Littré notes that older texts have only defiement or defiance for the noun.[6]

Earliest recorded meaning

Charles de Bourdigné's Légende joyeuse de Pierre Faifeu (1523) uses deffy in the sense “fear”.[2][6]

Semantic evolution

The noun followed the history of défier, first a feudal term for renouncing one's sworn faith and then “to provoke”.[7][4] Défi meant a challenge to single combat by 1575, in Brantôme, and then a provocation in general.[2][8] From 1847 (Balzac) it also meant a refusal to give in.[2]

Around 1965 it took the sense of an obstacle that a civilization must overcome, to render English challenge.[7]
