pénis (French)
Where does "pénis" come from?
The French word 'pénis' is a learned borrowing from Latin, where it originally meant 'tail' before evolving to describe the male reproductive organ. Linguists trace its roots back to the Proto-Indo-European word for 'tail,' suggesting a common ancestry with words for wings or feathers. While some theories link it to ancient terms for the organ itself, historical evidence suggests it began as a descriptive anatomical euphemism.
