The emergence of DP from a perspective of ontogeny and phylogeny: Correlation between DP, TP and aspect in Old English and first language acquisition
The aim of this paper is to discuss the English NP and its historical development into DP via the emergence of a functional D-system. This is related to the mechanism of theta-binding (Higginbotham 1985). The languages of the world could be described in terms of a D-system and morphological case. In addition, drawing on Abraham (1997) and Leiss (2000), I will examine if there is a complementary distribution between DP/TP and aspect. The correlation between DP/TP and aspect is observed in early child languages. This suggests that there might be a parallel between first language acquisition (ontogeny) and diachronic change (phylogeny) (cf. Osawa 2003a).
