Forms
sexo m (plural sexos)[1] Some 15th- and 16th-century writers used the Latin form sexu.[2][3]
Etymology
It is borrowed from Latin sexus (“sex, the state of being male or female”), a learned word.[4][5][6][1] Corominas first finds it in Santillana and in Alfonso de Palencia (1490), and dates it about 1440; the CDH has it in 1402.[4][5][2] It is not in Nebrija, Covarrubias or Don Quixote, but it is in Oudin's dictionary and in Góngora and Quevedo.[4]
French borrowed the same Latin word as French sexe in the 13th century.[7] Its counterparts include Italian sesso and the English word sex.[8][9]
sexus had a neuter doublet secus, always used with an adjective meaning “male” or “female”.[10] Since antiquity it has been compared with secō (“to cut”), the sexes being a division of the species; de Vaan finds the link possible but the formation of the word unclear.[10][11][12] Wiktionary traces it to Proto-Indo-European *sek- (“to cut”).[1]
Earliest recorded meaning
The first hit in the CDH is in Pero López de Ayala's Caída de príncipes (1402): commo del mejor sexo es a saber de varones ovo quatro & de fenbras ovo dos “of the better sex, that is of males, he had four, and of females two”.[2] The sense is the one the word still has, the division between male and female.[2][6]
Semantic evolution
Autoridades (1739) defined the word as what distinguishes male from female in animals, chiefly said of human beings.[13] Terreros used it for the part of the body that distinguishes man from woman, and recorded el sexo devoto for women.[8] The Academy's dictionary of 1843 extended it to plants, and that of 1899 has bello sexo for women as a whole.[14][15] Baralt (1855) accepted bello sexo as a widespread Gallicism, from French beau sexe, but rejected el sexo alone for women.[16]
Corominas notes the euphemistic use for the female genitals, which has ancient precedents in Pliny and Lactantius.[4] The 2001 Academy dictionary already had the senses “sexual organs” and “sexual pleasure”; the current one has “sexual activity” for the second.[17][6] The adjective sexual is a coinage of Álvarez de Cienfuegos (died 1809), mocked by Moratín, and was first admitted by the Academy in 1843.[4]

Sexo débil and bello sexo “women” are now used with a disparaging or discriminatory intent, and are labelled so by the Academy;[18] sexo feo and sexo fuerte are said of men.[6][18] The ⟨x⟩ is pronounced /ks/, or /ɡs/ in Wiktionary's transcription.[13][1]
