Saka language
Saka, or Sakan, was a variety of Eastern Iranian languages, attested from the ancient Buddhist kingdoms of Khotan, Kashgar and Tumshuq in the Tarim Basin, in what is now southern Xinjiang, China. It is a Middle Iranian language. The two kingdoms differed in dialect, their speech known as Khotanese and Tumshuqese. The Saka rulers of the western regions of the Indian subcontinent, such as the Indo-Scythians and Western Satraps, spoke practically the same language. Documents on wood and paper were written in modified Brahmi script with the addition of extra characters over time and unusual conjuncts such as ys for z.
