This word comes from Proto-Indo-Iranian *Hušā́s ("ušā" in Avestan), which in turn is from Proto-Indo-European *h₂éusōs ("dawn"), and is related to "ēṓs" in Greek and "aušrà" in Lithuanian. It is also the basis for the word "east" in Indo-European traditions, state Mallory and Adams.
The earliest recorded form of the name of this state is Maitanni, composed of a Hurrian suffix -nni added to the Indo-Aryan stem maita-, meaning "to unite" and comparable with the Sanskrit verb mith (मिथ्; lit. 'to unite, pair, couple, meet'). The name Maitanni thus meant the "united kingdom."[17]
Paralleling the evolution of Proto-Indo-Aryan máytʰati lit. 'he unites' into Sanskrit méthati (मेथति), the name Maitanni evolved into the later form Mitanni, where the stem maita- had given way to mita-.[17]
The earliest form of Sanskrit is that used in the Rig Veda (called Old Indic or Rigvedic Sanskrit). Amazingly, Rigvedic Sanskrit was first recorded in inscriptions found not on the plains of India but in in what is now northern Syria.
Between 1500 and 1350 BC, a dynasty called the Mitanni ruled over the upper Euphrates-Tigris basin, land that corresponds to what are now the countries of Syria, Iraq, and Turkey. The Mitannis spoke a language called Hurrian, unrelated to Sanskrit. However, each and every Mitanni king had a Sanskrit name and so did many of the local elites. Names include Purusa (meaning “man”), Tusratta (“having an attacking chariot”), Suvardata (“given by the heavens”), Indrota (“helped by Indra”) and Subandhu, a name that exists till today in India.
