The morphosyntax of wolof clefts

This paper examines the structure and derivation of cleft clauses in the Atlantic language Wolof, which possesses distinct clefts for subjects and nonsubjects. I argue that the clefts are based on two syntactically distinct copular constructions. In the subject cleft, the copula occurs with a TPstructure. In the nonsubject cleft, the copula occurs with a CPlike structure. In terms of derivation, I argue that Wolof clefts involve overt movement of the clefted constituent, not base generation. I show that Wolof clefts are islandsensitive using general and Wolofspecific tests. I then present evidence from a number of reconstruction tests that converge on the conclusion that clefted items in Wolof undergo A’movement.
