ABSTRACT
Core grammar (CG) is universal grammar’s substantive contribution to the grammar of a particular language. It consists of a set of general rules or rule schema (e.g., “move α”), conditions on rules (e.g., the recoverability condition for deletions), and filters (e.g., *[that [NP e]])—all of which provide a severely limited set of possible grammars from which certain properties of languages follow.1 The contents of the grammar are organized into various components, each with its specific properties. The various components interact modular fashion, in a way determined by the general organization of grammars. Following Chomsky and Lasnik (1977), we adopt the organization in (1).
