West Caucasian relative pronouns as resumptives
In polysynthetic West Caucasian languages, the morphological verbal complex amounts to a clause, with all kinds of participants cross-referenced by affixes. Relativization is performed by introducing a relative affix in the cross-reference slot which corresponds to the relativized participant. However, these languages display several cross-linguistically rare features of relativization. Firstly, while under the view of the verbal complex as a clause this affix appears to be a relative pronoun, it is an unusual relative pronoun because it remains in situ. Secondly, relative affixes may appear several times in the same clause. Thirdly, relative pronouns are not expected to occur in languages with prenominal relative clauses. Fourthly, in the Circassian branch, relative pronouns are identical to reflexive pronouns. These features are explained by considering relative prefixes to be resumptive pronouns. This interpretation finds a parallel in the neighboring East Caucasian languages, where reflexive pronouns also show resumptive usages. Finally, since in some West Caucasian languages the relative affix is a morpheme with a dedicated relative function but still shows properties of a resumptive pronoun, our data suggest that the distinction between relative pronouns and resumptive pronouns may not be so clear as is usually assumed.
