This name derives from the Ancient Germanic “*ner > *nerþuz”, meaning “power of life”. In Germanic paganism, Nerthus is a goddess associated with fertility. She is often identified with the Vanr Njörðr who is attested in various 13th century Old Norse works and in numerous Scandinavian place names. Nerthus is the feminine Latinized form of "Njörðr" as it would have looked like around the first century.
