Research on causative and applicative constructions has identified a class of symmetrical languages, in which either of two arguments may pattern like the direct object of a primary transitive verb. To date, symmetry of this sort has been identified only in a small geographically contiguous group of Bantu languages. Bajau, an Austronesian language of Indonesia and the Philippines, is shown to be symmetrical. Unlike the Bantu languages previously described, Bajau permits a benefactive applied object to be treated like an ordinary direct object. The restriction on the extraction of benefactive applied objects must therefore not be universal, contrary to the assumption of previous theories.
