A Form Set Approach to the CSC

Abstract

Since the formulation of the Coordinate Structure Constraint (CSC), extraction from coordinate structures has been observed to be illegitimate, but it is empirically challenged by exceptional cases. Given this, we propose that conjuncts in general are base-generated by Form Set (Chomsky 2020, 2021), being subject to the parallel structure constraint; extraction occurs in an across-the-board mode, capturing the CSC. Concerning the exceptional VP conjuncts where asymmetric extraction is allowed, we argue that they are properly labeled in the mode of syntactic restructuring (Choe 1988; Wurmbrand 2001) (Kim and Park 2021, 2022); accordingly, the requirement of the single event structure (Truswell 2007) is met, feeding sub-extraction. In short, this paper deduces the CSC by resorting to Form Set in tandem with labeling via restructuring.
