Nebraska city (5)
I believe the answer is:
omaha
'nebraska city' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for omaha that I've seen before include "place in Nebraska" , "State [CITY!!!]" , "- - Beach (WWII)" , "Cotton fabric used for curtains and upholstery" , "American-Indians" .)
