Forms

desafiar (first-person singular present desafio, first-person singular preterite desafiei, past participle desafiado)[1] The 13th century has both desafiar and desfiar; a Latin law of 1188–1230 already has desafidiet.[2][3]

Etymology

It is formed from Old Galician-Portuguese des- + afiar (“to pledge faith, trust”), from the Old Portuguese verb Old Galician-Portuguese afiar “to guarantee, keep faith with someone”, itself from a- and fiar (“to trust”).[2][4][5][1] Wiktionary takes the old verb from Vulgar Latin *afidō (“to trust”).[1] Cunha and Aurélio derive it from a first-conjugation form of Latin fīdō (“to trust”), and the DLP and Nascentes connect it with fidēs (“faith”).[4][5][6][7] Nascentes adds that the old verb for “to trust” disappeared because it clashed with afiar “to sharpen”, and that the compound first meant “to withdraw one's trust” and then “to call to combat”.[8][7]

The same formation on the Latin verb is Spanish desafiar, Occitan desfizar, French défier and Italian sfidare.[9][7] Wiktionary compares the English word defy.[1]

Bluteau (1713), following the seventh of the Spanish Partidas, explains that to challenge was to withdraw from the faith and friendship two noblemen had promised each other, which is why challenging belonged properly to the nobility.[10][2]

Earliest recorded meaning

Lorenzo's chronology finds desafidiet in a Latin law of 1188–1230 and desfiar in a Latin law of 1194 (sed quando eum desfiar, statim det sibi treugam “but when he defies him, let him at once grant him a truce”).[3][2] In Galician-Portuguese the Cantigas de Santa Maria have foi logo desafiado / dos parentes dela todos “he was at once challenged by all her kinsmen”, and a cantiga d'escarnho e mandou-me desafiar “and he sent to challenge me”.[3] The Crónica Troiana uses it both for challenging and for giving formal warning of enmity.[3]

Semantic evolution

The medieval sense is the formal challenge to combat or war between nobles or kingdoms.[3] Morais (1813) quotes heralds sent to declare war de Reino a Reino “from kingdom to kingdom”.[3][11] Already in the dictionaries of 1789 and 1813 it has the figurative senses “to show no fear of”, “to brave” (desafiar os perigos) and “to provoke, arouse” desire or curiosity.[12][11] Later dictionaries add “to invite” someone to a drink or a meal and “to tempt”.[13][5]

Today it also means to dare someone to do something difficult, to defy an authority openly and to put to the test; in Brazil it is used of challenging a singer to a desafio, a sung poetic contest.[2][14] The word passed into Tetum as dezafia.[1]
