Forms

testicule m (plural testicules)[1]

Etymology

It is borrowed from Latin testiculus (“testicle”), a diminutive from Latin testis (“testicle”), a word almost always used in the plural.[2][3][4][1] The anatomical sense is a special use of the same Latin word in the sense “witness”, the testicles being regarded as the witnesses of virility;[2][3][5] Plautus often plays on the two meanings.[2][3][5] Old French made the same image with tesmoings, literally “witnesses”, in the plural, recorded at the end of the 13th century.[2][3]

Bloch and Wartburg date the borrowing only to the 15th century, and the GLLF follows them, with a next record in Robert Estienne's dictionary of 1539.[6][7] Littré compares Occitan testicul, Spanish testiculo and Italian testicolo.[8]

Earliest recorded meaning

It is first recorded in 1304, in the Placides et Timeo, for the male genital gland.[2][3]

Semantic evolution

Brought into French by the anatomists, the word, mostly used in the plural, stayed a technical term of medicine, anatomy and botany, though it also became the ordinary name for the organ beside many familiar and vulgar synonyms such as couille.[3][5] It replaced the Old French tesmoings.[3]

At first it could name any genital gland: in 1575 the plural also meant the ovaries, a sense Littré still records; in the 18th century it narrowed to the male gland.[3][8] Learned metaphors gave it other senses that have now gone: the lower pair of the quadrigeminal bodies of the brain (1690–1771) and various univalve shells (1712–1876).[3][8]
