Eastern Iranian Languages

The Eastern Iranian languages are a subgroup of the Iranian languages emerging in Middle Iranian times (from ca. the 4th century BC). The Avestan language is often classified as early Eastern Iranian. The largest living Eastern Iranian language is Pashto, with some 50 million speakers between the Hindu Kush mountains in Afghanistan and the Indus River in Pakistan. As opposed to the Middle Western Iranian dialects, the Middle Eastern Iranian preserves word-final syllables.

The living Eastern Iranian languages are spoken in a contiguous area, in Afghanistan as well as the adjacent parts of western Pakistan, Gorno-Badakhshan Autonomous Province of eastern Tajikistan, and the far west of Xinjiang region of China, while it also has two other living members in widely separated areas, the Yaghnobi language of northwestern Tajikistan (descended from Sogdian) and the Ossetic language of the Caucasus (descended from Scytho-Sarmatian). These are remnants of a vast ethno-linguistic continuum that stretched over most of Central Asia in the 1st millennium BC.
