The development of a morphosyntactic analyzer of Tibetan texts aims to create a consistent formal grammatical description (formal grammar) of the Tibetan language, including all grammar levels of the language system from morphosyntax (syntax of morphemes) to the syntax of complex sentences and supra-phrasal entities. А new version markup is being created to reflect both the structures of the immediate constituents and those of dependency. The formal grammar reflects all classes of models, and their grammatical properties. Besides the module for formal grammar, token vocabularies, and a central module for Tibetan grammatical categories, their possible values, and restrictions on their combination are created.
