The status of the relativizer disi is difficult to establish. Case-marking is not at issue, but it may be preceded by a preposition; see Feature 94 "Instrument relative clauses". A pronominal status is also suggested by the occurrence of disi in relativized possessive constructions such as Wan pikien disi Mama lange tatá lassi. 'A child whose mother and father are dead' (van Dyk c1765: 11).
