Null Subject Romance Languages are languages in which the V feature of T is necessarily strong. Taking so much for granted, and given the morphological characteristics of this kind of languages, all their properties follow: V raising deposits at T a set of [-- interpretable] f -features that are erased through covert raising by the [+interpretable] f-features of the subject DP, either phonetically realized or pro (pro: a notational abbreviation for a set of features composed by the categorial feature D and f -features). Inverted subject (DP) and null subject (pro) are, therefore, vP internal subjects. The preverbal subject, in contrast, is a DP merged at T -therefore a non-argumentin a derivation with a pro as the internal subject. Starting from this basic proposal, the analysis of some new data points to the spurious character of Nominative Case in these languages and suggests that pro is only allowed in Spec, vP.
