Problems of projection
I presuppose here Chomsky (2013), including separation of projection (labeling) from the principles of construction of expressions. Assume further that for interpretation, syntactic objects must be labeled. It follows that Internal Merge is successive-cyclic leading to a criterial position, and is forced to ensure labeling. A further question is what Rizzi calls “the halting problem.” A simple solution is outlined. Special properties of subjects of CP are discussed: the Extended Projection Principle (EPP) and the Empty Category Principle (ECP). These can be unified under the labeling theory assumed, and the analysis is extended to the second phase v*P, where the object that is raised is in a structural position analogous to subjects of CP. Other outstanding questions also fall into place.
