Is there a ditransitive construction in Kokama-Kokamilla?

In Kokama-Kokamilla (KK), ditransitive constructions — i.e. syntactic units that profile three participants and contain two non-subject arguments — do not exist as a distinct type relative to transitives. KK shows both indirective and secundative alignment types (Haspelmath 2004, Dryer 1986, 2006), but no formal or behavioral evidence for a second object of any kind. In KK, typical three-participant events are syntactically encoded in at least three ways, none of which comprises two grammatical objects. Further, these findings suggest that no verb or construction profiles three participants in the sense of Goldberg (1995: 49). This paper adds to the literature on languages that code three-participant events by means of transitive clauses (Margetts & Austin 2007), which ultimately questions indirect object and secondary object as primitive notions as suggested by Dryer (1986).
