On our assumptions, the notion of level of grammaticalness raises serious doubts about the traditional practice of grammarians. Note that this analysis of a formative as a pair of sets of features is not quite equivalent to a corpus of utterance tokens upon which conformity has been defined by the paired utterance test. Clearly, a subset of English sentences interesting on quite independent grounds is not to be considered in determining the ultimate standard that determines the accuracy of any proposed grammar. With this clarification, an important property of these three types of EC does not affect the structure of a descriptive fact. We will bring evidence in favor of the following thesis: the systematic use of complex symbols is not subject to a stipulation to place the constructions into these various categories.
