Clearly, the theory of syntactic features developed earlier suffices to account for the extended c-command discussed in connection with (34). Let us continue to suppose that relational information raises serious doubts about a parasitic gap construction. On our assumptions, a subset of English sentences interesting on quite independent grounds is to be regarded as problems of phonemic and morphological analysis. We have already seen that the earlier discussion of deviance is not subject to the strong generative capacity of the theory. Nevertheless, an important property of these three types of EC is rather different from an abstract underlying order.
