Abstract
In this paper, I deal with the main means of expressing epistemic modalities in spoken Tibetan. These are not expressed by modal verbs, as is the case with many languages of the world but by other lexical and grammatical means.
These lexical means include, in particular, epistemic adverbs. The chief grammatical means to be found in the spoken language are morpho-syntactic, consisting of a system of epistemic verbal endings, which are discussed in detail in this paper from a formal and a functional point of view.
It further illustrates the use of epistemic verbal endings in different syntactic structures, i.e. their compatibility with various verbal constructions and verbal classes, including their use with secondary verbs (modal, aspectual and directional).
