“…Nerthus and the Vanir god Njǫrðr can be reconstructed as *nerþuz ('power'), 13 which has given rise to the interpretation of Nerthus and Njǫrðr as divine twins, as is often seen with fertility deities (such as the Nâsatyas recorded in Rigveda from c. 1900 BC). 14 The Vanir prosperity gods Freyr and Freyja also have a common Old Norse root -their names are generally thought to mean 'lord' and 'lady' 15 -and the siblings have been interpreted as a younger variant of Njǫrðr and Nerthus.…”
