In this article, I analyze ki (ǂHoan) and ko (Juǀ'hoansi) as heading vP internal functional projections dominating VP and dominated by vP. I show how this analysis provides a natural account for the various possible and impossible word orders in constructions involving locative and instrumental phrases. Lastly, I discuss the general implications of my analysis for the theory of Case checking in Chomsky (2000, 2001a,b).
