| summary | In the first part of the talk I will briefly present the system of Criteria for the expression of scope-discourse semantic properties: the left periphery of the clause is populated by a system of functional heads (Q, Foc, Top, etc.) which trigger A’-movement and guide interpretation at the interfaces with sound and meaning. Criterial configurations give rise to freezing effects: an element satisfying a criterion (e.g., a wh-phrase moved to the embedded C-system in an indirect question) is frozen in place and cannot be further moved (Rizzi 2006 and much related work). Issues of “further explanation” arise at this point: can freezing effects be derived from fundamental principles of linguistic computation?
In the second part I will present Chomsky’s (2013) approach to labelling, according to which a category created by Merge is labeled by the closest head (a case of minimal search, or relativized minimality). This approach combines the criterial conception of A’-movement with elements of Moro’s (2000) dynamic antisymmetry, and offers the promise of a comprehensive account of the “Halting Problem” of A’-movement: why is stepwise movement forced to continue in certain structural environments, and forced to stop in other environments? I will propose a particular implementation of Chomsky’s algorithm and illustrate its consequences w.r.t. different kinds of freezing effects. |
