Underlying the explicit formulation of possible syntactic processes together with possible structural descripton are the belief that the rules or constraints specifying allowable sequences of lexical and grammatical formatives in any nautral language can be given in a simple manner and the empirical hypothesis that the simplest formulation by the discovery of the principles best characterizes the unlimited manifestations of human linguistic competence. This empirical hypothesis is again predicated upon what has been called perceptual strategy which belongs in some as yet unexplored 'performance model'. The central convention governing the application of transformations is the theory of the transformational cycles, but its real status has not always been established adequately. Thus, precyclic, cyclic, postcyclic, lastcyclic and anywhere rules have been rather vacuously treated in varied arguments with very little supporting evidence. Under either the cyclic or linear conventions, it is necessary to distinguish those transformations that apply in the domain of each successive lower S node moving upward in the tree in a derivation (allcyclic) from those applying only on the top-most S node (last-cyclic). We can discern a formal difference between these two cyclic rules: the all-cyclic transformations preserve properties of base strings across their application (i.e., the output of such transformations is essentially of the same form as the input derived by CF grammar); the last-cyclic 'root' transformations radically deform the phrase markers to which they are applied, producing as output a structure not generable by the base, but which must necessarily be dominated by the root-S. However, this division is still inadequate in that some lower nodes as well as the topmost S permit root-like transformations in their domain if the subordinate clauses contain certain unique semantic features such as 'assertion'. Furthermore, there remains such a research strategy to introduce into non-surface levels some output conditions like Complex NP Constraint in order to preserve the acceptable base structures all through the derivation with respect to lexical insertion and the notion of 'lexical gap'. It is the thesis of this paper to pursue the formal nature of tree structures that involve especially COMP-node triggering certain cyclic transformations in context-free environments to the effect that they can serve to regroup some collapsible rules with reduntant generative capacity as one general operation. It is hypothesized that all-cyclic transformations apply prelexically and that it is not necessary to distinguish between prelexical and lexical transformations if and only if they are to be applied in those cyclic nodes specified by Node Admissibility Conditions. This research further suggests that the conventional dichotomy between main and subordinate clauses should be reconsidered and restructured toward such a universal stipulation as 'The Penthouse Principle', which is sure to provide a solid and substantial framework for the coming studies in the field of historical linguistics.
