The Scythian languages ( or or ) are a group of Eastern Iranian languages of the classical and late antique period (the Middle Iranian period), spoken in a vast region of Eurasia by the populations belonging to the Scythian cultures and their descendants. The dominant ethnic groups among the Scythian-speakers were nomadic pastoralists of Central Asia and the Pontic–Caspian steppe. Fragments of their speech known from inscriptions and words quoted in ancient authors as well as analysis of their names indicate that it was an Indo-European language, more specifically from the Iranian group of Indo-Iranian languages. Most of the Scythian languages eventually became extinct, except for modern Ossetian (which descends from the Alanian dialect of Scytho-Sarmatian), Wakhi (which descends from the Khotanese and Tumshuqese forms of Scytho-Khotanese), and Yaghnobi (which descends from Sogdian). Alexander Lubotsky summarizes the known linguistic landscape as follows: Classification The vast majority of Scythological scholars agree in considering the Scythian languages (and Ossetian) as a part of the Eastern Iranian group of languages. This Iranian hypothesis relies principally on the fact that the Greek inscriptions of the Northern Black Sea Coast contain several hundreds of Sarmatian names showing a close affinity to the Ossetian language. However, the classification of the Iranian languages in general is not fully resolved, and the Eastern Iranian languages are not shown to form an actual genetic subgroup. Some scholars detect a division of Scythian into two dialects: a western, more conservative dialect, and an eastern, more innovative one. The Scythian languages may have formed a dialect continuum: Alanian languages or Scytho-Sarmatian in the west: were spoken by people originally of Iranian stock from the 8th and 7th century BC onwards in the area of Ukraine, Southern Russia and Kazakhstan. Modern Ossetian survives as a continuation of the language family possibly represented by Scytho-Sarmatian inscriptions, although the Scytho-Sarmatian language family "does not simply represent the same [Ossetian] language" at an earlier date. Saka languages or Scytho-Khotanese in the east: spoken in the first century in the Kingdom of Khotan (located in present-day Xinjiang, China), and including the Khotanese of Khotan and Tumshuqese of Tumshuq. Another dialect of Scythian evolved into the Sogdian language. Another East Iranian language related to the Scythian is the Chorasmian language. Phonology The Scythian language possessed the following phonemes: History Early Eastern Iranians originated in the Yaz culture (ca. 1500–1100 BC) in Central Asia. The Scythians migrated from
