Tocharian script

The Tocharian script, also known as Central Asian slanting Gupta script or North Turkestan Brāhmī, is an abugida which uses a system of diacritical marks to associate vowels with consonant symbols. Part of the Brahmic scripts, it is a version of the Indian Brahmi script. It is used to write the Central Asian Indo-European Tocharian languages, mostly from the 8th century (with a few earlier ones, probably as early as 300 CE) that were written on palm leaves, wooden tablets and Chinese paper, preserved by the extremely dry climate of the Tarim Basin. Samples of the language have been discovered at sites in Kucha and Karasahr, including many mural inscriptions. Mistakenly identifying the speakers of this language with the Tokharoi people of Tokharistan (the Bactria of the Greeks), early authors called these languages "Tocharian". This naming has remained, although the names Agnean and Kuchean have been proposed as a replacement. Tocharian A and B are not mutually intelligible. Properly speaking, based on the tentative interpretation of twqry as related to Tokharoi, only Tocharian A may be referred to as Tocharian, while Tocharian B could be called Kuchean (its native name may have been kuśiññe), but since their grammars are usually treated together in scholarly works, the terms A and B have proven useful. A common Proto-Tocharian language must precede the attested languages by several centuries, probably dating to the 1st millennium BC. Given the small geographical range of and the lack of secular texts in Tocharian A, it might alternatively have been a liturgical language, the relationship between the two being similar to that between Classical Chinese and Mandarin. However, the lack of a secular corpus in Tocharian A is by no means definite, due to the fragmentary preservation of Tocharian texts in general. The Tocharian script is derived from the Brahmi alphabetic syllabary (abugida) and is referred to as slanting Brahmi.
