Abstract

This paper discusses the discourse contrasts that arise in connection to direct evidentiality in Southern Aymara (henceforth, Aymara), an understudied Andean language. Aymara has two direct evidentials, the enclitic _=wa_ and the covert morpheme _-_∅, which are used whenever the speaker has the best possible grounds for some proposition. I make the novel observation that a sentence with _=wa_ can be felicitously uttered if the speaker attempts to update the common ground by addressing an issue on the table. In fact, the sentence with _=wa_ that is uttered must be congruent with prior discourse; I tie this to the claim that _=wa_ is a (presentational) focus marker (Proulx in Language Sciences 9(1):91–102, 1987 ). This paper thus claims that _=wa_ is a marker that combines evidentiality and focus. In contrast, uttering a sentence with _-_∅ entails that the speaker’s contribution is already in the common ground, which likens this evidential to common ground management operators—there is no congruence requirement in this case. I identify which construction can be used in different discourse settings (conversation openers and telling anecdotes). I implement a formal analysis based on Farkas and Bruce (Journal of Semantics 27:81–118, 2010 ) and Faller (Semantics and Pragmatics 12(8):1–53, 2019 ) that links evidentiality and discourse.
