Analyzing interspeaker variation in Maay

This paper advocates an approach to interspeaker linguistic variation that aligns with the ‘I-language’ view (Chomsky, 1986). On this view, the object of study in linguistics is mental grammar; language is understood as being internal to the individual, in contrast to the ‘E-language’ approach, where language is external to individual speakers. This paper considers a case study from Maay (a Cushitic language spoken in southern Somalia) in which interspeaker variation in a refugee community defies analysis in E-language terms. An I-language approach allows for a straightforward analysis of the observed variation, specifically in the domains of plural noun formation and vowel length alternations.
