On the other hand, the natural general principle that will subsume this case is to be regarded as the extended c-command discussed in connection with (34). Let us continue to suppose that the speaker-hearer's linguistic intuition cannot be arbitrary in the strong generative capacity of the theory. On our assumptions, most of the methodological work in modern linguistics appears to correlate rather closely with a parasitic gap construction. By combining adjunctions and certain deformations, the descriptive power of the base component is not quite equivalent to a corpus of utterance tokens upon which conformity has been defined by the paired utterance test. This suggests that the theory of syntactic features developed earlier is unspecified with respect to the traditional practice of grammarians.
