Evidence for a VP-internal analysis of postverbal arguments in an SOVX language

Mande languages are known for their typologically unusual SOVX word order, in which the subject and direct object precede the verb, while adjuncts and other complements must follow it. Koopman (1992) argues for Bambara that this unique word order arises when the direct object obligatorily raises to a preverbal position for Case, while any other postverbal elements surface in their base-generated position within the VP. However, Nikitina (2019) proposes for Wan that postverbal elements are located in a high, clause-adjoined position. This paper presents syntactic evidence from Mandinka in support of the former analysis of postverbal indirect objects. In particular, I provide word order, pronominalization, and binding facts that show that postverbal indirect objects must be located in a low, VP-internal position, which is incompatible with a clausal-adjunction analysis.
