Pronunciation
Forms
confiar (first-person singular present confio, first-person singular preterite confiei, past participle confiado)[1] Houaiss records the spellings cõffiar in the 14th century and comffyar in the 15th; a letter of 1504 has quõfyado.[2][3]
Etymology
It is inherited from Vulgar Latin *cōnfīdō (“to trust”), the classical cōnfīdō moved from the third conjugation to the first, as Houaiss, the DLP and Aurélio reconstruct it; it is already spelt as now in 1214.[2][4][5][1][6] Cunha treats it in the article on fiar, which shows the same change.[7][8] Vieira, Silva Bastos and Figueiredo explained it instead as formed in Portuguese from com- and that verb.[9][10][11] Nascentes too derives it from the classical verb with a change of conjugation, but calls it a modern formation, although Lorenzo records it in the 13th century.[12][6]
The same Latin verb is Italian confidare, French confier, Catalan confiar and Spanish confiar.[13][14] The Latin verb is made of con- and fīdō (“to trust”), which goes back to *feiðō and *bʰéydʰeti (“to trust”).[15][1]
Earliest recorded meaning
The oldest record is in the testament of Afonso II of 1214: com eu en eles confio “as I trust in them”.[6] The Cantigas de Santa Maria use the verb intransitively with en, de and por, as in confiand'en Deus “trusting in God”.[6] The first sense is thus “to trust, rely on”.[6][16]
Semantic evolution
The transitive sense “to entrust, hand over in trust” followed the medieval “to trust in”: Cardoso (1569) translates the verb with Latin fido and confido, and Morais (1789) gives both “to have confidence, hope in” and, as old, “to hand over safely”.[17][18] Vieira adds “to communicate, confide” (confiar um segredo) and quotes Diogo do Couto's como de vós confio “as I trust you to”.[9] Houaiss distinguishes entrusting something or someone to another's care, entrusting a task, confiding a secret, and believing in someone's good faith.[2] Brazilian usage also has confiar de beside confiar em.[19][5]
