Using you to get to me: Addressee perspective and speaker stance in Duna evidential marking

Languages have complex and varied means for representing points of view, including constructions that can express multiple perspectives on the same event. This paper presents data on two evidential constructions in the language Duna (Papua New Guinea) that imply features of both speaker and addressee knowledge simultaneously. I discuss how talking about an addressee's knowledge can occur in contexts of both coercion and co-operation, and, while apparently empathetic, can provide a covert way to both manipulate the addressee's attention and express speaker stance. I speculate that ultimately, however, these multiple perspective constructions may play a pro-social role in building or repairing the interlocutors' common ground.
