Forms

bañar (first-person singular present baño, first-person singular preterite bañé, past participle bañado)[1] Old Spanish wrote it bannar and, in eastern texts, banyar.[2][3]

Etymology

It is inherited from Late Latin balneāre (“to bathe”), derived from Latin balneum (“bath”).[4][5][6][7] Like all the Romance forms, it rests on a Vulgar Latin form without /l/, *baneare, from *baneum, which simplified the awkward consonant cluster; the form without /l/ is found in an inscription at Pompeii.[4][1] The classical form survived only in place names such as ⟨Boñar⟩ and ⟨Albuniel⟩.[4]

The same Latin verb is Portuguese banhar, Catalan banyar, French baigner and Italian bagnare.[8][1] The French verb owes its vowel to bain.[8][9]

The Latin noun was taken from Ancient Greek βαλανεῖον (balaneîon, “bath”), early enough for the second /a/ to be reduced and lost.[1][10]

Earliest recorded meaning

Corominas dates the verb to the end of the 12th century, in the Libre dels tres reys d'Orient.[4][5] The CDH's earliest hit is in the Fazienda de Ultra Mar (c. 1200, in a 13th-century copy), where Pharaoh's daughter goes down a bannarse en el rio “to bathe in the river” and finds the ark.[3][2] The sense was immersing the body in water to wash.[11]

Semantic evolution

Thirteenth-century texts use it for bathing in rivers and public baths: the Fuero de Brihuega fines men who enter the baths on the women's days, and the Moamín tells falconers to dip their hawks in cold water.[3] Alfonso X's history already has the figurative bannada de lagrimas “bathed in tears”.[12] The Quijote uses it for rivers whose waters bathe the land and for faces bathed in blood and hands in tears.[13]

Autoridades in 1726 recorded the extended senses “to wet and water”, of rivers and the sea that touch a region or a city's walls, and “to cover one thing with another”, as sweets with sugar.[14] The Academy's dictionary has since added the light or sun that floods a place, and terms of shoemaking and painting.[6] In much of Latin America bañar is also used for taking a shower.[15] The phrase ¡vete a bañar! “go and take a bath!”, is a dismissive “get lost!” in Argentina, Cuba, Mexico and Uruguay.[6]
