Samnium is a Latin exonym for a region of Southern Italy anciently inhabited by the Samnites. Their own endonyms were Safinim for the country and Safineis for the people. The language of these endonyms and of the population was the Oscan language. However, not all the Samnites spoke Oscan, and not all the Oscan-speakers lived in Samnium.
