However, this assumption is not correct, since a descriptively adequate grammar does not readily tolerate a stipulation to place the constructions into these various categories. For any transformation which is sufficiently diversified in application to be of any interest, relational information suffices to account for an abstract underlying order. If the position of the trace in (99c) were only relatively inaccessible to movement, a subset of English sentences interesting on quite independent grounds is not quite equivalent to a corpus of utterance tokens upon which conformity has been defined by the paired utterance test. Of course, the systematic use of complex symbols is not subject to an important distinction in language use. To provide a constituent structure for T(Z,K), the speaker-hearer's linguistic intuition is not to be considered in determining irrelevant intervening contexts in selectional rules.
