The paper is devoted to Tibetan grammatical terminology. For this purpose Tibetan grammatical works corpus was created. At the same time Russian translations of the works were added to the corpus, so it is factually a parallel Tibetan-Russian corpus. The corpus represents the collection of grammar treatises of the Tibetan grammatical tradition formed in VII-VIII c. The corpus is useful to researchers of the Tibetan linguistic tradition as well as to those specialized in linguistic studies of classical and modern Tibetan and its teaching. On the basis of corpus a specific grammatical lexical dsatabase is created. The database will be useful both to tibetologists and general linguistics specialists.
