In spontaneous English, which clauses can deviate from traditional syntactic schemas by having a resumptive pronoun where a gap would otherwise be. Some researchers claim that such uses of which are not errors but rather a reanalysis. However, there is no consensus as to how which is being reanalyzed. Collins & Radford (2015) suggest that it behaves like a caseless relative pronoun; Sells (1985) and Kjellmer (1988) posit a subordinating conjunction behavior; Daalder (1989) posits a coordinating conjunction behavior; and Miller (1988: 116), Kuha (1994), Loock (2007) and Burke (2017) note that which can be replaced by both subordinating and coordinating conjunctions, but they do not commit to one over the other. Here, we present prosodic and syntactic data in which such uses of which behave more like a coordinating conjunction than like a relative pronoun or subordinating conjunction.
