Award by group in Nebraskan city (5)
I believe the answer is:
omaha
'nebraskan city' is the definition.
(I've seen this in another clue)
'award by group' is the wordplay.
'award' becomes 'OM' (order of merit).
'by group' becomes 'aha' (I can't justify this - if you can you should believe this answer much more).
'om'+'aha'='OMAHA'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for omaha that I've seen before include "American-Indians" , "Where American may work" , "American Indian" , "O, a ham found in US city on Missouri river" , "Largest city in Nebraska" .)
