The number of arguments a single verb can take depends on the type of verb. Ditransitive verbs are the most common verb structure head-marking that supports double object construction in most languages. Besides ditransitive, however, some languages have derived verb structures that support double construction. The author takes observation of applicative and causative constructions in Luganda and highlights some of the structural similarities between these constructions and ditransitive. He bases his joint analysis on the fact that the grammatical relations of the arguments of ditransitive, applicative and causative are closely related. In his analysis the author also shows where double object construction in Luganda differs from other Bantu languages.
