Bactrian language
Bactrian is a part of the Eastern Iranian areal group, and shares features with the extinct Middle Iranian languages Sogdian and Khwarezmian (Eastern) and Parthian (Western), as well as with the modern Eastern Iranian languages Pashto, Yidgha, and Munji. Its genealogical position is unclear. According to another source, the present-day speakers of Munji, the modern Eastern Iranian language of the Munjan Valley in northeast Afghanistan, display the closest possible linguistic affinity with the Bactrian language.
