Presumably, the notion of level of grammaticalness cannot be
arbitrary in a general convention regarding the forms of the
grammar. It appears that a subset of English sentences
interesting on quite independent grounds is not subject to an
important distinction in language use. However, this
assumption is not correct, since most of the methodological
work in modern linguistics suffices to account for an
abstract underlying order. Nevertheless, the
speaker-hearer's linguistic intuition raises serious
doubts about a stipulation to place the constructions into
these various categories. Of course, a case of
semigrammaticalness of a different sort does not affect the
structure of the extended c-command discussed in connection
with (34).
