The emergence of the D system and the demise of morphological case in English
In this paper I discuss the English NP and its diachronic development into DP via the introduction of a D system within nominals. Since NPs are inherently predicative, and N has a R(eferential)-role, that R-role must be bound, if NP is to be used as an argument. Either a functional category D or morphological case binds the R-role. Since there was no DP in OE, and the status of nominal projections was NP, morphological case bound the R-role. When morphological case disappeared, a syntactic D system was introduced to bind the R-role. Further evidence for this assertion is the absence of gerund constructions in OE, since gerunds are one instantiation of a D system.
