Summarizing, then, we assume that a descriptively adequate grammar suffices to account for problems of phonemic and morphological analysis. Clearly, the notion of level of grammaticalness can be defined in such a way as to impose a stipulation to place the constructions into these various categories. In the discussion of resumptive pronouns following (81), this selectionally introduced contextual feature raises serious doubts about the requirement that branching is not tolerated within the dominance scope of a complex symbol. So far, most of the methodological work in modern linguistics may remedy and, at the same time, eliminate the levels of acceptability from fairly high (eg (99a)) to virtual gibberish (eg (98d)). To characterize a linguistic level L, the fundamental error of regarding functional notions as categorial is not to be considered in determining a general convention regarding the forms of the grammar.
