Abstract
This paper documents relative clause constructions in the polysynthetic Circassian languages of the West Caucasian
family and attempts to establish diachronic links between them. It is shown that the Circassian languages possess both
externally-headed and internally-headed relative clauses, with the latter having semantic heads that are interpreted outside of
the relative clause. In addition, these languages have constructions which cannot be unequivocally assigned to one type or the
other, and have properties of both. This paper suggests that there is a diachronic explanation for this, but also argues that the
contrast between externally-headed and internally-headed relative clauses is not as clear-cut as is usually assumed in the
typological literature.
