You could add any of the other person prefixes e.g. yi-djirridjbun 'you [singular] are washing it]' ngune-djirridjbun 'you two are washing it', ngurri-djirridjbun 'you [three or more] are washing it', ka-djirridjbun 'he or she is washing it', kabene-djirridjbun 'they two are washing it', kabirri-djirridjbun 'they [three or more] are washing it'. And there's plenty more where they came from...
