The Sino-Tibetan language family is the second largest in the world, and standard Tibetan is the most widely spoken language in the Tibetic group. A comprehensive introduction to epistemicity in standard spoken Tibetan, this book examines the grammatical expression of a variety of epistemic modalities—rather, the myriad ways in which a speaker indicates their confidence in the knowledge on which their statement is based—through numerous examples of epistemic types. It elucidates the complex system of epistemic verbal endings and epistemic copulas, or connecting words, employed in the spoken language, analyzing them from semantic, syntactic, and pragmatic viewpoints.
