Pronunciation

  • Portugal: /ˈfɛ/[1]

Forms

fé f (plural fés)[1] Old Galician-Portuguese wrote fe and fee.[2][3] Cunha records fee into the 15th century.[3] Feijó in 1734 prescribes fé, not fee.[4]

Etymology

It is inherited from Latin fidēs (“trust, faith, pledged word”), written Old Galician-Portuguese fe and Old Galician-Portuguese fee in the oldest texts.[5][3][1] Nascentes derives it from the accusative through *fede, which gave the old two-syllable form.[6] In the cantigas it rhymes with words in open /ɛ/, a vowel that Michaëlis explains as the fusion of the two vowels of the older form.[2]

The same Latin word is Galician fe, Spanish fe, Catalan fe, French foi and Italian fede.[7][1] The Spanish word too had an older form Old Spanish fee, which Corominas finds in documents up to the 16th century.[8]

The Latin noun is from Proto-Italic *fiþē- and Proto-Indo-European *bʰidʰ-eh₁- (“faith”), the zero grade of *bʰeydʰ- (“to trust”), which is also behind fīdō (“to trust”) and foedus (“treaty”).[9][1]

Earliest recorded meaning

Houaiss's date of 1111 comes from a Latin charter.[5] The earliest Galician-Portuguese record in the DDGM is a charter of 1262: E ontre nos ande senpre bõa fe dambalas partes “and let there always be good faith between us on both sides”.[2] Here, as in the oaths of the cantigas, the word means loyalty to one's word.[2]

Semantic evolution

The cantigas use fé above all in oaths and assurances: per bõa fé “in good faith, truly”, a la fé “indeed”, fé que devedes “by the faith you owe”, and the popular bofé.[2][10] The Cantigas de Santa Maria and the Crónica Geral also use it for the Christian religion, a sancta fe catolicha, and for loyalty.[2] In notarial Galician of the 15th century dar fe meant “to certify”, and the notary's fe gave a document its authority.[2]

Bluteau in 1712 defines it first as one of the theological virtues, and Morais in 1813 distinguishes divine faith, resting on revelation, from human faith, resting on testimony.[11][12] Modern dictionaries keep the religious, legal and everyday senses side by side.[5][13] In Brazilian use botar fé and levar fé mean “to trust”.[14]

The word passed into Konkani.[1]
