Resumptive pronouns are produced in English in unguarded speech in restrictive relative clauses and appositive relative clauses. However, numerous studies have found that resumptive pronouns in restrictive relative clauses are not acceptable. To our knowledge, no studies have examined the acceptability of resumptive pronouns in appositive relative clauses, despite hints in the literature that they may be more acceptable in appositive than in restrictive relative clauses. This article fills that gap. We found that resumptive pronouns were rated as more natural in appositive relative clauses than in restrictive relative clauses. These findings may be due to which currently undergoing a reanalysis from a relative pronoun to a solely connective word, as has been suggested in the literature. A small-scale corpus search also reveals that appositive relative clauses with resumptive pronouns are increasing in American English.
