The two primary goals of this article are to present data concerning the mood-based alignment split that can be observed in Panará pronominal clitics and to put forward a tentative formal analysis that can capture the motivations of such phenomena in the grammar. This paper aims to explore an approach to mood from a simple syntactic perspective, in which different sets of features active in the narrow syntax suffice to derive the case marking phenomena that are correlated with mood in Panará.
