This article discusses how evidential and egophoric making is used to manage knowledge in interaction. To this end, it analyzes interactional data from Wutun (mixed Sinitic, Northwest China) and Upper Napo Kichwa (Quechuan, Ecuador). Wutun has an egophoric marking system, which, according to the definition of egophoricity, encodes involvement/lack of involvement in the described event. Upper Napo Kichwa has a set of evidentials, which, according to theory, encode the source of evidence for a given proposition. The two languages are typologically unrelated. However, when we look closely at how speakers of Wutun and Kichwa use epistemic markers, we discover functional similarities not predicted by the dominant definitions of epistemicity and evidentiality. In both languages, the use of the markers is conditioned by the interpersonal context of the interaction, and speakers use egophoric and evidential marking to signal their epistemic rights and responsibilities with respect to other speech-act participants.
