托卡里语是印欧语族的两种相关古代语言，分别称为托卡里A语和托卡里B语[1]。这些语言主要通过6-8世纪发现于新疆丝绸之路沿线的佛教文献得以保存[1]。托卡里文献出土于新疆吐鲁番、库车和图木舒克等地[1]，其中托卡里A语主要出现在吐鲁番和卡拉沙地区，而托卡里B语的分布范围更为广泛[1]。
托卡里语的命名源于1907年F.W.K.缪勒及其后的Sieg与Siegling的提议[1]。作为地理位置最东的古代印欧语言，托卡里语属于centum语言分支[1]，在印欧语言研究中占据特殊地位。目前这些古代语言的学术研究资源已在线发布，便于学者研究和教学[1]。
An online academic resource for Tocharian, a pair of related ancient Indo-European languages, has been made available through digital platforms [1]. Tocharian consists of two distinct but linguistically related tongues—Tocharian A and Tocharian B—whose surviving texts have been preserved primarily through Buddhist religious literature discovered along the Silk Road in Xinjiang during the 6th to 8th centuries [1].
The geographic distribution of these languages reflects their historical presence across Central Asia. Tocharian A texts were primarily found in the Turfan and Krashe regions, while Tocharian B materials show a wider geographic spread across archaeological sites including Turfan, Kucha, and Tumshuk [1]. The naming and identification of these languages emerged through scholarly work beginning in 1907, when linguist F.W.K. Müller first proposed the designation, with subsequent refinements contributed by Sieg and Siegling [1].
Tocharian holds particular significance within Indo-European linguistic studies. The language family represents the geographically easternmost branch of ancient Indo-European languages and belongs to the centum language classification [1]. The availability of these online resources reflects continuing academic interest in documenting and studying one of the most remote members of the Indo-European language family.
