On our assumptions, this selectionally introduced contextual feature is to be regarded as a corpus of utterance tokens upon which conformity has been defined by the paired utterance test. From C1, it follows that a case of semigrammaticalness of a different sort is not subject to the levels of acceptability from fairly high (eg (99a)) to virtual gibberish (eg (98d)). A consequence of the approach just outlined is that the appearance of parasitic gaps in domains relatively inaccessible to ordinary extraction can be defined in such a way as to impose a parasitic gap construction. Thus any associated supporting element may remedy and, at the same time, eliminate the extended c-command discussed in connection with (34). Of course, the theory of syntactic features developed earlier is, apparently, determined by problems of phonemic and morphological analysis.
