Locative inversion in English and Chicheŵa shows remarkable similarities which can be explained by hypothesizing the same underlying argument structures and principles for mapping argument structure roles into syntactic functions. However, the alignment of roles with syntactic categories reflects a profound typological difference between the two languages: Chicheŵa categorizes locatives in a gender class system; English, in an abstract case-like system. The resulting syntactic differences defy analyses within a widely-assumed architecture of Universal Grammar and support the alternative adopted by Bresnan & Kanerva 1989.
