fiel m or f (plural fiéis)[1]
Etymology
It is inherited from Latin fidēlis (“trustworthy, faithful”), written Old Galician-Portuguese fiel in the oldest texts.[2][3][1] The Latin adjective is formed from fidēs (“faith, trust”) with the suffix -ēlis.[1][4]
The same Latin word is Galician fiel, Asturian fiel, Spanish fiel, Occitan fidèl, Old French feel and Italian fedele.[1][5]
Earliest recorded meaning
The Cantigas de Santa Maria of the 13th century have the adjective in un monge bõo, cast' e mui fiel “a good monk, chaste and very faithful”, and use it as a noun for the Virgin as a guarantor: Fiel bõo tenno “I have a good surety”.[6][2] A charter of 1276 asks men to be uassalos fieles “loyal vassals” to the abbot, and one of 1278 speaks of the fiéés de nostro señor, the faithful of the Lord.[6]
Semantic evolution
Lorenzo's chronology dates the noun to 1152 in the sense “help”, the religious sense “believer” to the 14th–15th century, and the office of a fiel to the 15th.[6] In the Crónica Geral a fiel is a person entrusted with a disputed matter until the case was decided, an overseer of public services, or the judge of a judicial duel; the modern “faithful, believer” is there too.[6] Morais (1789) adds os fieis defuntos “the faithful departed”, those who died in the communion of the Church, and memoria fiel “a memory that does not fail”.[7] Figueiredo (1899) records the noun for an employee who keeps goods, papers or money, an assistant treasurer, and as old usage for arbitrators.[8] Houaiss adds the nautical senses and, in Rio Grande do Sul, the leather loop at the end of a whip handle.[2][9]

Usage notes
The fiel of a balance, the needle or tongue that shows whether the beam is level (fiel da balança), is a separate noun, recorded from the 16th century.[2] Houaiss takes it from Spanish fiel de la balanza (1490), which Corominas explains from Latin filum “thread”, used for this pointer by Isidore of Seville: in the phrase fil de la balanza the old form fil was confused by folk etymology with the adjective fiel.[2][15][16] Figueiredo had derived it from fio “thread”.[8] Figuratively it means a guiding principle.[2]
