culo m (plural culos)[1]

Etymology

It is inherited from Old Spanish culo, inherited from Latin cūlus (“backside, arse”).[2][3][4][1] In Latin it was a popular word, found in graffiti, satire and the Priapea, and it survives in all the Romance languages.[5][6]

The same word is Portuguese cu, Galician cu, Asturian culu, Catalan cul, French cul, Italian culo and Romanian cur.[7][8][9]

De Vaan traces the Latin word to Proto-Italic *kūlo- (“back”) and Proto-Indo-European *kuH-lo- (“backside, rear”), with cognates in Celtic: Old Irish cúl (“back”) and Welsh cil (“corner”).[10] The older derivation from a root *(s)kewH- (“to cover”) has been given up, because LIV no longer recognises that verbal root; de Vaan considers instead *keh₂u- (“to cleave”), the root he also sees in Latin cauda (“tail”).[10][1] Wiktionary calls the origin uncertain, though most likely shared with Proto-Celtic *kūlos (“posterior”).[1]

Earliest recorded meaning

The first record is in the Fuero de Avilés of 1155, among four insults the charter deals with when neighbours quarrel: „fotudo i culo”.[2][11] Several other town charters of the 12th and 13th centuries name the same insult among the forbidden words, as a fragment of 1182 does: „Verba vetata sunt fodido en culo et puto gaffo” “the forbidden words are fodido en culo and puto gaffo”.[12][13]

Semantic evolution

The Diccionario de Autoridades defines it as the human backside, sometimes an animal's haunches, and also names the end of a cucumber and the losing side of the knucklebone (taba) in the game; among its phrases are culo de pollo for a badly sewn, bulging stitch, and dar con el culo en las goteras for someone who squanders his money and ends up poor.[14] The Academy added the sense “anus” in 1843 and culo de vaso “a fake gem” by 1869.[15][16] Modern dictionaries also record the drop of liquid left at the bottom of a glass.[4][17]

In Spain the word is colloquial, while in Latin America it is generally felt as coarse.[18] It has many regional senses there: “cowardly” in Mexico, “luck” in Argentina and Uruguay, a woman in Central America and Peru, the female genitals in Guatemala and Cuba.[19][1] In Asturias and León it is also the eye of a needle and a tree stump.[2][20]

Some derivatives came from other languages: culata “butt of a gun” (1611) probably from Italian, and recular “to back away” (1607) probably from French.[2][3]
