Indo-Aryan superstrate in Mitanni

Some loanwords in the variant of the Hurrian language spoken in Mitanni during the 2nd millennium BCE are identifiable as originating in an Indo-Aryan language; these are considered to constitute an Indo-Aryan superstrate in Mitanni (or in Mitanni Hurrian). The words are theonyms, proper names and technical terminology related to horses (hippological).

It is generally believed that Indo-Aryan peoples settled in Upper Mesopotamia and northern Syria, and established the kingdom of Mitanni following a period of political vacuum, while also adopting Hurrian. This is considered a part of the Indo-Aryan migrations.
