ABSTRACT
This chapter discusses Dryer who represents a single language, Kombai, also refers as double-headed in addition to that of externally headed pre-nominal, externally headed post-nominal, internally headed, headless, correlative, and adjoined, relative clauses (RCs). It discusses that relative clauses in Kombai combined the features of externally-headed and internally-headed relative clauses in a single structure: they have both an external head noun and a noun corresponding to the head noun inside the relative clause. For Kombai, however, there seems to be positive evidence that the rightmost of the two NPs is the external head of the RC, modified by the RC containing an internal head. The chapter explores document that seemingly bona-fide double-headed RCs in other languages and language families, even when they do not constitute the prevalent RC strategy, but only an alternative strategy, available in selected contexts. It discusses some implications of double-headed RCs for the gener.
