バクトリア語
Müller's identification became a minority position among scholars when it turned out that the people of Tokharistan (Bactria) spoke Bactrian, an Eastern Iranian language, which is quite distinct from the Tocharian languages. Nevertheless, "Tocharian" remained the standard term for the languages of the Tarim Basin manuscripts and for the people who produced them. A few scholars argue that the Yuezhi were originally speakers of Tocharian who later adopted the Bactrian language.
