A morphosyntactic account of verbal number in Mupun

In this paper, I argue that verbal number is Agree with either a DP (resulting in participant number reading) or an Adverbial Phrase (giving rise to an event number interpretation). Several facts support this claim: mismatches between the number features on the verb and on its argument, the role of the external argument for verbal number dinstinctions, the ambiguity between the two functions (participant plurality/event plurality) and the morphological productivity of the category. The analysis considers data from two Chadic languages, Mupun and Mwaghavul, and is couched in Minimalist Syntax and Distributed Morpholog
