Abstract

In this paper we will analyze the conceptual and computational motivations of the property of displacement in natural languages from a revisited perspective. We will account for displacement phenomena proposing our own version of displacement-as-external token Merge, as opposed to the traditional displacement-as-literal movement or, more recently, displacement-as-copy and Merge (Chomsky 1995; Kitahara 1997; Nunes 2004). As far as empirical data is concerned, we will provide a brief analysis of parasitic gaps and their derivation, comparing our proposal with previous accounts making particular stress on the idea that operations are not feature-driven in a highly constrained syntactic component, but interface-driven, syntax being free and unbounded.
