Laz, an endangered South Caucasian language, combines features of theoretical interest such as active-ergative case alignment, phi-agreement with objects (besides subjects), and oblique subjects. Based on novel data from the Pazar (Atina) dialect of Laz, this study reports yet another phenomenon to be available in the language: subject/agent pseudo-incorporation. Documenting how this interacts with the case system, phi-agreement system, and oblique subjects in the language, we argue for a unified analysis which postulates a null expletive subject in case of incorporation. Our proposal also resolves a long-standing problem that subject/agent pseudo-incorporation in Turkish posits for a dependent-theoretic account of accusative.
