Do Subjects Have a Place in Spanish?
Overt preverbal subjects in Spanish have been claimed to be in an adjoined, peripheral layer of the clause and in IP-layer. Part of the motivation for the different analyses stems from mixed A and A-bar properties they display. I argue that subjects do not appear in a single, unique position, but rather in several functional projections along the extended verbal projection. Consequently, different A and A-bar properties are expected. In some cases, the properties of those projections will be determined in the course of the derivation: if a verb raises to a certain projection, it will render this projection active for agreement purposes and trigger movement of the subject to its specifier.
