Forms

arnés m (plural arneses)[1]

Etymology

It is borrowed from Old French harneis, modern harnais.[2][3][4][1] The French word is probably from Old Norse *herrnest (“army provisions”), a compound of herr (“army”) and nest (“provisions for a journey”).[3][2][4] The DHLF traces the Norse form to *harinest, with Frankish *hari (“army”), and explains the French ending as remodelled on the suffix ⟨-eis⟩, ⟨-ois⟩.[5] Brøndal opposed this etymology.[3] Older Spanish dictionaries derived it from a Celtic word for iron.[6][7]

The prestige of French chivalry spread the word to other languages: Italian arnese, English harness and German Harnisch.[5] Portuguese arnez also comes from the French.[8]

Earliest recorded meaning

The CDH's earliest hit is in a prose translation of the Cantigas de Santa María made before 1284, of men who wore the swords with which a knight had been killed a carona de sus arnes “next to the skin, under their armour”.[9] Corominas's first record is in the Cortes of 1385.[3][4] The Cortes of León and Castile required every man worth twenty thousand maravedís or more to keep hun arnés complido “a full armour”.[7]

Semantic evolution

From the start the word also meant equipment in general: the Fueros aragoneses of 1350 require each man to bring his arneses to the works, and Juan Fernández de Heredia writes of horses and armour kept ready in each village and of arneses de cambra, household goods.[9] Corominas glosses the old senses as defensive armour fitted to the body, each piece of a horse's harness, and household goods.[3] Old Spanish had the verb arnesarse “to put on armour”, in the Cancionero de Baena.[3]

By 1817 the Academy defined it as the old steel armour fastened with straps and buckles.[10] In 1846 Domínguez also had the room where the harness of the horses was kept, and the plural for the trappings of saddle and pack animals and, figuratively, for the things needed for any purpose; the Academy gave both plural senses in 1899.[11][6] The modern sense, a frame of straps fastened to the body to hold or carry something or someone, as in climbing or parachuting, is in the Academy's dictionary by 2001.[12][13]
