The pragmatics of addressee-based Hausa demonstratives

Item type: Journal Article • Journal: South African Journal of African Languages • Authors: Malami Buba --- Africa Department, ENGLAND

In this paper, I describe the pragmatic coding of addressee-deictics in Hausa. This flows from the framework proposed in Buba (1997a). I shall provide further evidence that the two-term (speaker-proximal vs. speaker-distal) system used to describe most European languages cannot...
