- An analysis involving reduplication is not well supported. Synchronically (and diachronically) it could be related to fiiyu/fiiya 'son/daughter', but these words have their own regular plurals fiiyus/fiiyas. An equally plausible analysis is that it is a reduction of fiiyus fiiyas 'sons and daughters'.
