Rodent seen in Nottingham's terrible (7)
I believe the answer is:
hamster
'rodent' is the definition.
(I know that hamster is a type of rodent)
'in nottingham's terrible' is the wordplay.
'in' says the answer is hidden in the clue.
'HAMSTER' can be found hidden inside 'nottinghams terrible'.
'seen' is the link.
(Other definitions for hamster that I've seen before include "Oddly, the arms of a rodent" , "one running round in circles?" , "Short-tailed burrowing rodent" , "Common pet rodent" , "Kind of rodent with cheekpouches, often a pet" .)
