Pronunciation

  • /ˈfɾeno/, [ˈfɾe.no][1]

Forms

freno m (plural frenos)[1] Old Spanish wrote freno and ffreno.[2]

Etymology

It is inherited from Latin frēnum (“bridle, bit”).[3][4][5][1] It is frequent in charters of the earliest period and in texts of every date.[3]

The same Latin word is Portuguese freio, earlier Old Galician-Portuguese frẽo, Galician freo, Catalan fre, older fren, French frein, Italian freno and Romanian frâu.[6][7][8][9][1]

De Vaan reconstructs Proto-Italic *frēno- and connects it, as Walde and Hofmann did, with frētus (“relying on”), from a stem meaning “to support”, which he finds simpler than Ernout and Meillet's link with frendō (“to gnash”); his reconstruction is Proto-Indo-European *dʰr-eh₁-no- (“holding”).[10] Gómez de Silva follows the second view, the bit being what horses grind their teeth on.[11]

The verb frenar is not the Latin frēnō continued: Corominas takes it for a Spanish derivative of the noun, since Autoridades still called it rare, and it replaced the older refrenar and enfrenar.[3]

Earliest recorded meaning

Corominas's first record is a charter of 962, in Oelschläger's list; the Cantar de mio Cid (c. 1140, in a 14th-century copy) has horses de siellas e de frenos todos guarnidos “all fitted with saddles and bridles”.[3][12] The first sense is the iron bit and bridle of a horse or mule.[3][13]

Semantic evolution

Alfonso X's prose has both the horse's bridle and the figurative “check, restraint”, as when God puts a freno on men's greed.[13] Covarrubias recorded no saber de freno, said of someone like an untamed beast, and the related verbs enfrenarse, refrenarse and desenfrenarse.[14] The Diccionario de Autoridades defined it as the iron instrument put in a horse's mouth, and by extension the whole headstall, and figuratively a restraint that keeps someone from doing wrong.[15]

The mechanical sense, a device that slows or stops a machine, entered the Academy's dictionary in 1884, and carriages were added in 1899; today it is the first sense.[16][17][5] The Academy recorded morder el freno “to resist control” in 1817, and Domínguez tascar el freno “to champ the bit” in 1846.[18][19] In Mexico, Guatemala, Ecuador, Peru and Panama the word also names a dental brace.[20][1]

  • 1532 – the first record from the Americas, in Mexico.[21]
  • 1611 – Covarrubias records no saber de freno; the derivative frenillo is first recorded in the same year.[14][4]
