Pronunciation

Forms

pénis m (invariable)[1]

Etymology

It is borrowed from Latin pēnis (“tail, penis”).[2][3][1] The Latin word first named the tail of mammals, in which sense it was replaced by cauda, the source of queue, and was also used for the male member.[3][4][5] Rey notes that it is an old word, found in Plautus, but popular and rare, avoided because of its meaning.[3] He derives it, with a suffix in -ni-, from Proto-Indo-European *pesos, also seen in Sanskrit and in Ancient Greek πέος (péos, “penis”).[3]

Earliest recorded meaning

It is first recorded in 1618, in Guillemeau's Ostomyologie.[2][4]

Semantic evolution

Unlike the Latin word, pénis belongs in French to learned and anatomical language.[3][6] The adjectives pénial (1805, in Cuvier) and pénien were derived from it.[2][3]
