ses (Esperanto)

Where does "ses" come from?

The Esperanto word 'ses' traces its origins back to the Proto-Indo-European root '*swéḱs'. This root evolved into the Latin 'sex', which has served as the foundation for the number six across many languages, eventually being adopted directly into Esperanto.
