Relative, completive, interrogative and negative clauses: a proposal for a unified analysis of the CP domain in the language of the Oro Waram and Oro Waram Xijein peoples (Txapakura family)

This paper investigates relative, completive, interrogative and negative clauses in the language spoken by the Oro Waram and Oro Waram Xijein peoples (Txapakura family) in light of the generative theory. In theoretical terms, we propose there is a parallelism among these structures as the CP head is instantiated by the complementizers ka and ko. Furthermore, these constructions provide syntactic evidence that agreement on this language mainly depends on the syntactic position of each core argument. On the one hand, there is a specific agreement paradigm for moved subjects and another for in situ ones, on the other hand object agreement is realized only when there is no movement.
