A quaternary epistemic code

Evidentiality has often been described in narrow terms as an independent grammatical category denoting an overt source of information (e.g., perception, inference, assumption and hearsay). Drawing on fieldwork data, this paper explores how evidentiality is encoded at the copula level in Chhitkul-Rākchham (West Himalayish). In doing so, it is argued that the relevant evidentials, part of a comparatively complex scheme consisting of nine elements, together with a negative sub-system, fall under the broader umbrella of epistemic modality. The contention finds an illustration in an egophoric marker following two inflectional tracks with two resulting degrees of assertiveness, and in a handful of combinatorial constructions. Evidentiality as expressed by copulas points to the self, which builds bridges with the study of consciousness. The latter term is underappreciated within linguistics and this work emphasizes the need for a broader cross-disciplinary outlook.
