Extraction asymmetries show that type A coordination is adjunction: Supplementary material

Abstract: Ross (1967) observed that the coordinate structure constraint can be violated in certain semantically asymmetric structures. In this article we consider one of these structures, namely type A coordination, in detail (the terminology is from Lakoff 1986; an example is Here's the whisky I went to the store and bought ). We present experimental evidence showing that the pattern of argument and adjunct extraction from type A coordinate structures matches the pattern of argument and adjunct extraction from structures containing rationale clauses in all crucial respects. This near-perfect parallel behavior suggests that, like rationale clauses, the second conjunct in a type A coordination is an adjunct (see also Brown 2017). We explore the consequences of this finding for both interpretive and syntactic analyses of asymmetric coordination.
