Clefting and nominal predication: Two focus-marking constructions in Movima

Movima (isolate, Bolivia) has two focus constructions that superficially look very similar. One is a simple clause with a noun in predicate position and a verb placed inside the argument phrase. Its pragmatically marked status stems from the inversion of the prototypical association of lexical and pragmatic categories. In the other construction, the predicative noun is additionally preceded by a free pronoun. This construction is a cleft, the pronoun and noun together constituting an equational matrix clause. The two constructions also differ in function: the simple clause with a nominal predicate is a simple predication, while the cleft is a specificational sentence.
