Dyirbal and Gumbaiŋgar are alike in that (1) possessive phrases and relative clauses are marked by the same or similar affixes, probably cognate between the two languages; and (2) the syntax of possessive phrases is similar. Relative clause constructions are on the surface less similar: in Dyirbal the relative clause marker is always attached to the verb, but in Gumbaiŋgar it is attached sometimes to the verb and sometimes to a noun. It is shown that in each language possessive phrases can be dealt with as a special instance of the relative clause construction; and that a common set of rules can be set up for the two languages, but with different conditions and slightly different ordering. An ‘affix transfer’ rule is needed to generate all possessive phrases (but is not required for relative clauses) in Dyirbal; in Gumbaiŋgar this rule is needed for all possessive phrases and for some relative clauses. The syntactic similarity of the two languages may be evidence of genetic relationship.
