Chicago NFL team (5)
I believe the answer is:
bears
'chicago nfl team' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for bears that I've seen before include "Large animals, polar or brown" , "Big animals" , "Massive mammals with shaggy coats" , "Ursine animals" , "Large animals, polar or grizzly" .)
