Symmetry and antisymmetry in syntax

摘要

New evidence is provided that Romance Clitic Right-Dislocation cannotbe the mirror image of Clitic Left-Dislocation nor its covert counterpart.It is also shown that an analysis postulating two leftward topic positions(Split-Topic Analysis) is more adequate on both conceptual andempirical grounds, since it complies with the highly restrictive view ofsyntax imposed by Kayne's Linear Correspondence Axiom, and offers aprincipled explanation of the consistent set of similarities and differencesbetween Clitic Right-Dislocation and Clitic Left-Dislocation.
