freno

Forms

freno m (plural freni)^[1] Old Italian texts write the word also as fren, frino and frenu.^[2]

Etymology

It is inherited from Latin frēnum (“bit, bridle”), the bit placed in a horse's mouth.^[3][4][5][1] The Latin word is continued across the Romance languages: French frein, Occitan fre, Catalan fre, Spanish freno, Portuguese freio, Sardinian frenu and Romanian frîu.^[4][6][7] DEI adds that it passed into the Celtic languages and into Albanian.^[8]

The origin of the Latin word is disputed.^[9][1] DELI, Nocentini and Devoto derive it from Latin frendō (“to gnash the teeth”), so that the bit was first “what the horse grinds its teeth on”;^[3][4][10] Nocentini traces the root to the same Indo-European source as English grind.^[3][4][10] De Vaan finds this possible but awkward, since it requires a nasal infix in the verb, and prefers the old connection with Latin frētus (“relying on”), from a stem meaning “to support”.^[9] Wiktionary follows this second view, deriving it from Proto-Indo-European *dʰer- (“to hold”) through Proto-Italic *frēnom.^[1]

Earliest recorded meaning

The oldest record is in the Monza Glossary of the 10th century, with the sense of the harness to which the reins are fastened to guide an animal.^[3][2] The figurative sense of a curb on excess appears before 1250 in Giacomo da Lentini.^[3][5]

Semantic evolution

In Old Italian the word named the metal bit fastened to the reins, and by metonymy the whole harness; many set phrases came from riding, such as senza freno “unbridled”, col freno sciolto “with loose reins” and stringere il freno “to pull on the reins”, often used figuratively.^[2] Dante speaks of lo fren de l'arte, the restraint of art, the artist's sense of measure, and Petrarch of holding the freno of a country, that is, its government.^[5]

The mechanical sense, a device that slows or stops a vehicle or machine, is recorded from 1869 in Tommaseo–Bellini's dictionary.^[3][11] It has since become the main sense, with many technical compounds (freno a disco, freno a mano, freno a tamburo).^[5][12] From Italian the mechanical sense passed through Venetian into Turkish as fren, and Greek has φρένο (fréno) from Italian too.^[8][1]
