Headless Relative Clauses in Sierra Popoluca

This chapter presents the first investigation of headless relative clauses in Sierra Popoluca, a Mixe-Zoquean language spoken in the southern part of the state of Veracruz, Mexico. It shows that Sierra Popoluca exhibits a very productive system of headless relative clauses. The language has free relative clauses of all three major types attested crosslinguistically and, remarkably, all three types can be introduced by almost all the wh-words that can occur in wh- interrogative clauses. It also has two types of light-headed relative clauses, both with demonstrative pronouns as their “light heads”: those which are introduced by a relative subordinator and those that are introduced by wh-words—the same two strategies attested in headed relative clauses in Sierra Popoluca. Finally, the language has one more variety of headless relative clause that lacks both a light head and a wh-word.
