Abstract
The main goal of this paper is to describe and compare the adposition classes of two Ghana-Togo
Mountain (GTM) languages: Tafi (KA-GTM) and Sɛlɛɛ (NA-GTM). The core of the preposition classes in the two languages
consists of a (general) locative and comitative prepositions, with Tafi showing the grammaticalization of a number of
verb forms into prepositions. Both languages exhibit the postpositional use of body part nouns and locatives. There
are debates as to whether Kwa languages have two classes of adpositions. The paper argues that both languages indeed
have two adposition classes – prepositions and postpositions and shows the asymmetry in the distribution of the
members of each class in both languages.
