Rangu (?)
Reportedly a name related to haymaking, perhaps a stack/stook of stale or musty hay, but nothing conclusive, despite its being named in 2000 . There is a spring and a village in Marjamaa, but this is unlikely an origin. It is also Muhu dialect for fly, which we can probably disregard. Unresolved. Mini hay-related group. See Saadu.
