The paradigmaticity of evidentials in the Tibetic languages of Khams

This article argues that the evidential system of Khams Tibetan, a cluster of Tibetic languages spoken in the south-eastern Tibetosphere, should be considered a verb paradigm. We propose a paradigm with six evidential categories (egophoric, statemental, visual sensory, nonvisual sensory, sensory inferential, and logical inferential) for all the verb classes. We focus on two varieties – rGyalthang and Lhagang – and examine how these evidential categories are encoded with distinct morphemes. We then discuss the main evidential forms of the copulative and existential verbs available in Khams Tibetan varieties as a whole, as well as their morphological relationship. Our analyses lead us to argue against a differential treatment of evidentiality depending on verb categories. The article concludes that describing the evidential paradigm may be the first essential task in writing a grammar of a Tibetic language.
