Forms
fiel m or f (masculine and feminine plural fieles, superlative fidelísimo)[1] An older form fidel is found in early charters and in Berceo.[2]
Etymology
It is inherited from Old Spanish fiel, inherited from Latin fidēlis (“faithful”).[2][3][4][1] Corominas explains the kept ⟨f⟩ as in fe: the word was pronounced without a diphthong until late, so neither the diphthong nor a wish to avoid a clash with hiel “gall”, as Steiger thought, is the reason.[2] The Latin adjective is formed from fidēs (“faith, trust”) with the suffix -ēlis.[1][5]
The same Latin word is Portuguese fiel, Galician fiel, Asturian fiel, Italian fedele and Occitan fidèl.[1][6][7]
Earliest recorded meaning
The Cantar de mio Cid (c. 1140, in a 14th-century copy) has the word in the Cid's greeting: ¡Venides, Martín Antolínez, el mio fiel vassallo! “You have come, Martín Antolínez, my faithful vassal!”.[8][2] The first record in a contemporary manuscript is a will of the 13th century, which pays for masses for los fieles de Dios “God's faithful”.[8]
Semantic evolution
Alfonso X's prose uses the word for loyal people and, as a noun, for Christians who live by the precepts of the Church; one passage applies it to those who follow the law of the Old Testament.[9] The old noun for faithfulness was fieldad, in a charter of 1206 and still in Nebrija; fidelidad, from Latin, appears in 1490.[2] Nebrija in 1495 glosses fiel both as a person one trusts and as one who believes in the faith.[10]
Covarrubias defines the word as one who keeps faith and loyalty, and Autoridades adds a thing that works as it should, such as a clock that keeps time, and a Catholic Christian, por antonomasia.[11][12][13] Today it also means “exact, true to the facts”, as of a copy or a memory, and a believer of any religion.[4]

Usage notes
A separate word fiel, the pointer of a balance, comes from the obsolete fil “pointer of a balance”, from Late Latin filum “thread”, the name Isidore used for it; in the phrase fil de la balanza it was confused with fiel “faithful”, and both fil and fiel are first found in Alonso de Palencia in 1490.[14][15][4] By the same image the word named officials who checked weights and measures (1495) and the fiel ejecutor (1499).[15] In Old Spanish and in Asturian fiel is also the gall, hiel.[16][7]
