Preverbal subjects in null subject languages are not necessarily dislocated

Abstract

In recent work on null subject languages it has been claimed that preverbal subjects are always (clitic-)left dislocated. In this paper, we argue against this claim, on the grounds of empirical evidence from European Portuguese concerning agreement facts, asymmetries between preverbal subjects & clitic-left dislocated XPs with respect to minimality effects, the existence of languages with a mixed system (null expletive subjects & full referential ones), language acquisition data, the behavior of negative QPs & interpretation facts, & propose a non-uniform analysis of preverbal subjects & clitic-left dislocated XPs that derives their topic interpretation from a predication rule stated configurationally (section 2). Our account of the SVO & VSO orders displayed in European Portuguese relies on a specific formulation of the EPP parameter, on the locality constraint Attract Closest X & on the independently motivated claim that V-movement targets T in European Portuguese (section 3). Under our analysis, the computational system generates equally economical SVO & VSO derivations & discourse considerations, at the appropriate interface, rule out the unfelicitous ones. 39 References.
