Zam

m (Zām) is the Avestan language term for the Zoroastrian concept of "earth", in both the sense of land and soil and in the sense of the world. The earth is prototyped as a primordial element in Zoroastrian tradition, and represented by a minor divinity Zam who is the hypostasis of the "earth". The word itself is cognate to the Baltic 'Zemes' and Slavic 'Zem', both meaning the planet earth as well as soil.
