I seem to have a lot of problems with this 'saudara' word. Why can't it be 'my brother, my sister'? I don't see what makes it not singular here.
actually, brother = saudara (singular), and brothers = saudara-saudara (plural)
we got a term call saudara-mara to indicates relatives, indonesian language got this?
no, there is no such a word in Indonesian
