This edited volume brings together work on the evidential systems ofTibetan languages. This
includes diachronic research synchronicdescription of systems in individual Tibetan varieties
and papersaddressing broader theoretical or typological questions. Evidentiality inTibetan
languages interacts with other features of modality interactional context and speaker knowledge
states in ways that provideimportant perspectives for typologists and our general understanding
ofevidential systems. This book provides the first sustained attempt tocapture this complexity
and diversity from both a synchronic anddiachronic perspective.
