What's the true etymology of Indo-Iranian WIWASWANT (Indian Vivasvat, Avestan Vivanhat)?
 
*VI- "divergent preffix"  cf. IE *wi-
*-VAS- "to burn, to shine" cf. IE xawes- / xwes->wes- / xaus-
-VAT "suffix   cf. IE -went- / -wnt
 
The Indo-Iranian *Wiwaswant was the father of *Manus, the first Man.
 
Was he originally the sun-god? a fire-god? other one?
