What's the etymology of MARS?
 
MARS < MAVORS
 
1- MAVORT- < *MARVORT- ? < *MARMORT- ? (cf. Mamercus < *Ma(r)-merti-cus )
2-   *-VORT- < IE *-wrti-  ? cf. fravashi, Sanskrit -vrti-
3- MAV- like Anatolian God Mav (cf. Maionia) ?
4- Etruscan Maris < Mars or viceversa?
5- Is there any etymology for Latin mas (gen. maris) ? cf. Sansrit pu-mams "man" ?
