Tocharian is an extinct branch of the Indo-European languages spoken in the Tarim Basin of present-day Xinjiang, China, until approximately the 9th century AD. Its discovery in the early 20th century fundamentally altered the understanding of Indo-European migrations and linguistic geography. The languages are preserved in a rich corpus of Buddhist and Manichaean manuscripts found at major oasis sites along the Silk Road.

History and Discovery

The existence of these languages was unknown until archaeological expeditions in the late 19th and early 20th centuries uncovered manuscripts in the Tarim Basin. Key figures in their discovery and study include explorers like Sven Hedin and Sir Aurel Stein, who led expeditions to sites such as Dunhuang and the Kucha region. The decipherment was pioneered by scholars including Emil Sieg, Wilhelm Siegling, and later Walter Couvreur, who identified the texts as belonging to a previously unknown Indo-European group. These manuscripts were primarily recovered from important monastic libraries and ruins at oasis cities like Turfan, Kucha, and Shorchuk, areas that were part of the historical Kucha Kingdom and under the influence of the Tang dynasty.

Languages and Classification

The family consists of two distinct but closely related languages: Tocharian A (also known as Agnean or East Tocharian) and Tocharian B (Kuchean or West Tocharian). Tocharian A was used liturgically around Turfan and Qarashahr, while Tocharian B was a living administrative and literary language in the Kucha Kingdom. As a Centum language within the Indo-European languages, it shares this characteristic with branches like Greek, Celtic languages, and Germanic languages, rather than the neighboring Indo-Iranian Sanskrit or Iranian languages. This classification places it as an independent, early-diverging branch of the Proto-Indo-European language.

Writing Systems and Texts

The languages are written in a derivative of the Brahmi script, specifically a Central Asian variant known as Slanting Brahmi. The vast majority of surviving texts are translations of Buddhist scriptures, including fragments of the Jataka tales, the Prajnaparamita, and works from the Vinaya and Abhidharma canons. Other significant finds include monastery administrative records, commercial documents, and a smaller number of Manichaean and medical texts. Important manuscript collections are held in institutions like the Berlin State Libraries, the British Library, and the Institut de France.

Phonology and Grammar

The phonology exhibits a system of eight vowel phonemes and a complex set of consonants, including a series of palatalized sounds. Grammatically, it is characterized as an agglutinative language within the Indo-European languages, a rare trait. It features a complex verbal system with present, preterite, and subjunctive moods, and a nominal system with cases including the genitive, perlative, and comitative. The syntax generally follows a Subject–object–verb order, similar to other ancient languages of the region like Saka and Old Uyghur.

Vocabulary and Influence

The core vocabulary retains many Proto-Indo-European language roots, such as words for kinship, numerals, and basic verbs, demonstrating its ancient divergence. However, it also contains significant loanwords from neighboring languages, including Sanskrit and Prakrit for religious terminology, as well as from various Iranian languages like Khotanese Saka and Middle Persian. There is also evidence of influence from and contact with Old Turkic and Chinese. Some linguistic hypotheses suggest possible early contacts with Uralic languages or even Anatolian languages.

Culture and Society

The Tocharian-speaking peoples were integral to the Buddhist culture that flourished along the Silk Road in oasis cities like Kucha, a major center of Sarvastivada Buddhism. They engaged in extensive trade and cultural exchange across networks connecting China, Bactria, and Gandhara. Artistic evidence from sites like the Kizil Caves and Dunhuang shows a synthesis of Greco-Buddhist, Iranian, and local styles. Their society eventually declined and was assimilated following the expansion of the Uyghur Khaganate and the Islamization of the Tarim Basin.
