Following Pylkkänen (2002), among others, many of the functions of the vP have been distributed between two independent projections: VoiceP and vP. Pylkkänen proposed a “bundling” parameter: some languages project a single bundled Voice/vP, and all functions depend on that single projection, and others project VoiceP and vP separately, and functions are distributed. The chapter first reviews the roles ascribed to these projections: (i) external argument introduction, (ii) event argument introduction, (iii) accusative case checking, (iv) introduction of causative or inchoative semantics, (v) verbalizing of nonverbal material, and (vi) demarcating a cycle. The chapter then reviews support for Pylkkänen’s parametric view of Voice-bundling from, e.g., Hiaki, Turkish, Korean, and English. Results on causatives from Key (2013) and Jung (2014) suggest that the projection sequence dominating v may form part of a predetermined projection hierarchy. The constraint against stacking productive morphological causatives may thus be attributed to the extended verbal projection.
