Forms
buey m (plural bueyes)[1] Old Spanish also wrote bue, boy, buy and boe, with the plurals bues, bueis, bueys and bueyes;[2] Nebrija still uses the plural bueis.[3][2][4] Leonese and Salamanca have bué, and Asturian güe.[5][6]
Etymology
It is inherited from Vulgar Latin *boem, from Latin bōs (“ox, cow”) (accusative bovem).[4][7][8][1] The accusative was reduced to *boe, which gave Old Spanish buee and then the modern form.[7][9] The final /e/ closed to /i/ in hiatus after the stressed vowel, so that the word ends in a triphthong.[10]
The same Latin word is Portuguese boi, Galician boi, Asturian güe, Catalan bou, Occitan buòu, French bœuf, Italian bue and Romanian bou.[11][12][1] The Judaeo-Spanish form is Ladino buey.[1]
The Latin noun continues Proto-Indo-European *gʷṓws, the word of Ancient Greek βοῦς (boûs), Sanskrit गो (go) and English cow.[1][13] Its initial /b/ is not the regular Latin outcome of the inherited labiovelar, which would have given a form with /w/, so the word is generally held to have been taken from a Sabellic language such as Umbrian bum (accusative).[13][14][1]
Earliest recorded meaning
Corominas's first record is a charter of 1184 in Oelschläger's list.[4][7] The earliest CDH context is the commandment in the Fazienda de Ultra Mar (c. 1200, in a 13th-century copy): ni cobdicies … so buey, ny so asno, “do not covet his ox, nor his ass”.[15]
Semantic evolution
In Old Spanish the word already meant the castrated male used for ploughing, as it does today.[16][2] Covarrubias (1611) pointed out that Latin bos named both sexes, while Spanish buey is only the castrated bull and vaca the female.[17]
The Diccionario de Autoridades (1726) defined it as a castrated bull useful for working the land, and recorded the hunter's buey de caza, a painted dummy ox behind which the hunter hides.[18][18] In the slang of thieves the plural meant playing cards, which the Academy recorded in 1884.[19][8] In Mexico and Central America buey is used for a stupid person and, in Mexico, as a familiar word for a friend, often written güey.[20][1][21]

Usage notes
The DLE has a separate buey of unknown origin, a rough measure of a large flow of water, a heavy gush of water from a channel, and a wave breaking through a ship's port.[8] The DRAE of 2001 had derived it from Greek bólos “throw”, while Autoridades took buey de agua from the size of an ox.[26][18] Phrases include poner el carro delante de los bueyes and the Río de la Plata hablar de bueyes perdidos “to talk of trifles”.[1]
