The possessor in an adnominal possessive construction is marked by the preposition blanga/bla (in the speech of younger speakers in the Victoria River variety and Fitzroy Valley variety also bo) which also has various other functions (benefactive, purpose, topic of conversation). It can be used with full NPs as well as pronominal possessors, and in both alienable and inalienable relationships. At least in the Roper River variety, proper nouns can also be juxtaposed to the possessum (Munro 2005: 180). Juxtaposition as a strategy is also available for pronominals (see Feature 37 "Marking of pronominal possessors").
