This paper describes the creation of the parallel Tibetan–Russian corpus of works of the Tibetan grammatical tradition that formed in the 7–8th centuries AD. On the basis of the corpus, a special lexical base of grammatical terminology is formed that could be of interest for Tibetologists and specialists in general linguistics. The corpus can be used for linguistic research, teaching, and the study of the classical and modern Tibetan language, as well as the Tibetan grammatical tradition.
