In-situ and ex-situ wh-question constructions in Moro

This paper addresses the formation of wh-questions in Thetogovela Moro, a Kordofanian language spoken in the Nuba Mountains of Sudan. Moro has both in-situ and ex-situ wh-questions, but exhibits a subject/non-subject asymmetry: while non-subjects may employ either construction, subjects must appear in the ex-situ form. Ex-situ wh-questions are analyzed as wh-clefts, and they share several properties with clefts and relative clauses. The fronted element is marked with a cleft particle and for noun phrases, a demonstrative that we analyze as a relative pronoun is used. Verbal tone patterns are those that are found in dependent clauses rather than main clauses. Subject questions, clefts and relative clauses are marked with a verbal prefix é-, while non-subject questions, clefts and relative clauses are marked with a verbal prefix ´-. We analyze these prefixes as dependent clause markers and provide evidence of additional dependent clause uses in the language. Finally, non-subject wh-questions bear an optional particle n ´- on the subject and/or verb. We offer several arguments that this is best analyzed as a complementizer
