The latter occurs as a modifier in t.oN-dse gi'wa-zhiN-ga 'birds of the
prairie lands', presumably htaN'ce=ki waz^iN'ka.  This seems to involve a
postposition =ki that might match IO =gi 'in' (c^hi'naN=gi 'in the city')
or Winnebago =(e)gi 'in'.  There's nothing like this that I'm aware of in
OP, unless maybe -gi in wakkaNdagi 'water monster; wonderful'.
