1. ri dwags “wild (herbivorous) animals”
2. g.yung dwags “domestic animals”
3. yi dwags “hungry ghost”
4. la dwags (a place name)

Does bla dwags “name/designation” belongs to this group as well? Perhaps dwags means “to roam” or “to reside”? There does not seem to be so many words that contain dwags.
