Pronunciation

Forms

sex n (plural sexe or sexuri)[1] The old plural is sexuri: „Instrucție egală și întreagă pentru tot românul de amândouă sexurile” “equal and complete schooling for every Romanian of both sexes” (1848).[2][3]

Etymology

It is borrowed from French sexe, at the same time borrowed from Latin sexus, one of the learned words of the 19th century.[4][3] DEX, MDA2, the DLR and Tiktin give both sources, while Scriban and Wiktionary name only Latin, and DER only French.[4][3][2][5][6][1][7] The French word was itself remade in the 13th century after the Latin one, from the older ses.[8]

The origin of the Latin word is unclear: it has often been linked with secō (“to cut”), as a “division” of a species into male and female, but the formation is obscure.[9][10][8]

Earliest recorded meaning

Tiktin dates the word from a text of 1828, and MDA2 from Episcupescu's Practica doctorului de casă of 1846.[5][3] Negulici's dictionary of 1848 defines it as the physical difference between male and female.[11]

Semantic evolution

The word first meant the set of features that distinguish male from female, and each of the two groups so distinguished; the 19th-century quotations are mostly about people “of both sexes”.[2][3] Joking collective phrases followed: sexul tare “the stronger sex” for men, sexul slab or frumos “the weaker, the fair sex” for women.[6][4] Old texts also used it for grammatical gender.[3]

MDA2 records the senses “genital organ” and, as rare, “sexual activity”.[3] The sense “sexual intercourse” is now common, and Volceanov's slang dictionary gives it as “sexual act; sex life”.[12][1] Compounds after English, such as sex-shop, came in from the 1970s.[13]
