Mitanni-Aryan

Some theonyms, proper names and other terminology of the Mitanni are considered to form (part of) an Indo-Aryan superstrate, suggesting that an Indo-Aryan elite imposed itself over the Hurrian population in the course of the Indo-Aryan expansion.

In a treaty between the Hittites and the Mitanni (between Suppiluliuma and Shattiwaza, c. 1380 BC), the deities Mitra, Varuna, Indra, and Nasatya (Ashvins) are invoked. Kikkuli's horse training text (circa 1400 BC) includes technical terms such as aika (Vedic Sanskrit eka, one), tera (tri, three), panza (pañca, five), satta (sapta, seven), na (nava, nine), vartana (vartana, round). The numeral aika "one" is of particular importance because it places the superstrate in the vicinity of Indo-Aryan proper (Vedic Sanskrit eka, with regular contraction of /ai/ to [eː]) as opposed to Indo-Iranian or early Iranian (which has *aiva; compare Vedic eva "only") in general.

Another text has babru(-nnu) (babhru, brown), parita(-nnu) (palita, grey), and pinkara(-nnu) (pingala, red). Their chief festival was the celebration of the solstice (vishuva) which was common in most cultures in the ancient world. The Mitanni warriors were called marya (Hurrian: maria-nnu), the term for (young) warrior in Sanskrit as well; note mišta-nnu (= miẓḍha,~ Sanskrit mīḍha) "payment (for catching a fugitive)" (Mayrhofer II 358).
