ABSTRACT
Copular sentences play an important role in showing the empirical and theoretical advantages of Dynamic Antisymmetry in a broad sense. As illustrated in section 3.1, on the one hand, they do not fit into the theory that considers movement as a way to delete uninterpretable features; on the other, they constitute a prototypical case where a point of symmetry needs to be neutralized. In this appendix, I will synthetically illustrate the fundamental issues of the unified theory of copular constructions originally proposed in Moro 1988 and expanded in much subsequent work (see Moro 1997b for a comprehensive illustration).
