Pronunciation

Forms

défaire[1] Old French desfaire, also written deffaire and desfere.[2][3]

Etymology

It is formed from French dé- + faire.[2][4][5][6] Wiktionary instead takes Old French desfaire from Early Medieval Latin disfaciō.[1] The base verb faire is from Latin faciō (“to do, to make”).[5]

Littré compares Italian disfare.[3]

Earliest recorded meaning

It is first found about 1100 in the Chanson de Roland: L'ost des Franceis verrez sempres desfere, “you will soon see the army of the French break up”, of an army broken up for departure.[2][3]

Semantic evolution

From the start défaire meant to change or undo what had been made or ordered, hence to destroy and to overcome someone.[7][8] It meant “to put to death” from about 1160, a sense now obsolete, and the past participle was said of a body ravaged by illness in Béroul's Tristan (late 12th century), the origin of the modern sense “altered in looks by fatigue or emotion”.[2]

The pronominal se défaire de “to get rid of” was first said of a person (about 1306, Joinville) and then of a thing (1424–1457).[2] The military sense “to rout, to defeat” is recorded from the Cent Nouvelles nouvelles (1456–1467), and gave the noun défaite “rout” (1475).[2][7][5] Commynes uses it for removing a ruler from power (1489–1491), and Scarron for disconcerting someone (1651).[2][8]
