The paper investigates the syntax and semantics of an indirect causative construction, ‘make’ causatives, in Sason Arabic with a focus on the syntax of the embedded structure and the status of the implicit embedded agent. On the basis of several diagnostics, the study demonstrates that ‘make’ embeds an agentive VoiceP, which also manifests an active-passive alternation despite the absence of any morphological reflex. Regarding the nature of the implicit embedded agent, the paper argues that it is present as a free variable à la Heim (1982) generated on the Voice head itself. In so doing, it adds to the ontology of null arguments as well as suggesting that licensing of a grammatical object is dissociated from the projection of a specifier.
