Since its inception, proponents of Generalized Phrase Structure Grammar (GPSG) have claimed the superiority of the analyses that the theory makes available for certain problematic constructions in English. Two examples of such constructions are (1) rightward unbounded dependencies (including right node raising) and (2) parasitic gaps. However, as GPSG has evolved, various steps taken in its development to provide adequate explanations of central properties of English and other languages have rendered invalid previous claims concerning these two constructions, to the extent that there is no obvious way in which the resulting paradoxes can be resolved in the current therapy.
