fe f (uncountable)[1]

Etymology

It is inherited from Latin fidēs (“faith, trust; credit; a promise, pledged word”).[2][3][4][1] The Latin accusative fidem gave first fee and then fe, as pedem gave pie and videt gave ve.[2][1] The older form is still found now and then in the Middle Ages and even in the 16th century: three times in a document of 1206, in the Conde Lucanor, in the Cancionero de Baena and in Saint John of the Cross.[2]

Corominas holds that the kept /f/ is not a sign of learned origin: here, as in falta and falso, the pronunciation of the educated prevailed over the popular one, which alone at first had the aspirated /h/.[2] The popular form with /h/ did exist: the rustic speech of Golden Age plays has the oaths ⟨a la he⟩ and ⟨mia he⟩, and the first already occurs in Juan Ruiz.[2] Corominas derives Basque alafede (“by my faith”) from an archaic Castilian a la fede.[2]

The same Latin word is Portuguese fé, Asturian fe, Catalan fe, Occitan fe, French foi and Italian fede.[5][6][7][8]

The Latin noun belongs to the family of fīdō (“to trust”), with fidēlis (“faithful”) and perfidia (“faithlessness”).[9] Wiktionary derives it from Proto-Indo-European *bʰeydʰ- (“to command, persuade, trust”), the root also of Proto-Germanic *bīdaną;[1] the OLD compares Ancient Greek πείθω (peíthō, “to persuade”) and πίστις (pístis, “faith”).[10]

Earliest recorded meaning

Corominas dates the word to the earliest texts of the language, the Cantar de mio Cid among them.[2][3] In the Cid, known from a 14th-century copy, it means a pledge of loyalty or a solemn promise: „con grand jura meted ý las fes amos que non las catedes en todo aqueste año” “with a great oath pledge your faith, both of you, that you will not look into them all this year”.[11][12]

Semantic evolution

Old Spanish used the word for trust, for religious belief and for a promise of loyalty, and in oaths and assurances such as a la fe and a buena fe “truly, certainly”.[13] Alfonso X's prose has belief without proof, trust in a person and a solemnly pledged word.[14]

In 1611 Covarrubias listed a promise, fidelity, credence, conscience (estar en buena fe or en mala fe), the authentic testimony that a notary gives, the certificate fe de vida that someone is alive, and finally the theological virtue.[15] The Diccionario de Autoridades put the theological virtue first, and the Academy kept that order through its 2001 edition; the DLE now begins with the body of beliefs of a religion.[16][17][18][4] The sense “fidelity”, as in conjugal fidelity, appears in the Academy's dictionary of 1869.[19] Phrases include buena fe “uprightness, good faith”, also a legal standard of honest conduct, and the printer's fe de erratas, a list of errata.[4][20]

  • 1514 – first record in the Americas, in Darién, for a notary's attestation.[22]
  • 1611 – Covarrubias lists the senses from “promise” to the theological virtue.[15]
  • 1726–1739 – the Diccionario de Autoridades defines it first as the theological virtue.[16]

Usage notes

De buena fe and de mala fe mean “in good faith” and “in bad faith”.[4][7] The DLE lists a second fe, without an etymology: an obsolete adverb meaning “behold”, the same as he (he aquí).[4][18][25] In Alfonso X's Lapidario fe is also the name of the Arabic letter for /f/.[14][26]
