Pronunciation

Forms

rut m (plural ruts)[1] Old French ruit, used until the 16th century;[2][3][4] rut is the form of the western dialects.[2][3][4]

Etymology

It is inherited from Old French ruit, inherited from Late Latin rugītus (“roaring”), from Latin rugiō (“to roar”), which also gave rugir.[5][6][2][3] The Latin noun was used especially for the bellowing of the stag seeking a hind.[5][2][3] For the change of vowel in the modern form, the TLFi and Bloch and Wartburg compare futé.[5][3]

The French sense is shared by Friulian rût, also arût, alone, while Spanish ruido means noise.[5][3][2] The French word is a doublet of rugi, the past participle of the verb.[1]

Earliest recorded meaning

It is first found about 1160 as ruit in the Roman d'Énéas, meaning sexual desire.[5][4]

Semantic evolution

From Wace's Roman de Rou (1160–1174) the word, in tens du ruit, was used of mammals that mate at fixed seasons, the sense that has lasted.[5][4] Old and Middle French also used it for noise and tumult (about 1245), keeping the Latin sense.[5][3][2] The form rut is found at the end of the 14th century.[5] Figuratively it means agitation or ferment (Goncourt, 1857), and familiarly the sexual excitement of people, mainly in en rut.[5][2]

English borrowed the word from Old French in the early 15th century.[7]
