This paper is concerned with subject relative clauses in Dagbani, a Mabia language spoken in northern Ghana, as these have received little attention in the literature compared to other relative clause constructions. We will argue that a successful syntactic analysis depends on a double headed relative clause structure, with one relative clause internal and one relative clause external head. In addition to discussing the syntax of an understudied language, the paper thus provides further evidence for relative clauses being based on double headed structures, at least in some languages.
