Uncommon sense in a German city (5)
I believe the answer is:
essen
'a german city' is the definition.
(city in Germany)
'uncommon sense' is the wordplay.
'uncommon' indicates an anagram.
'sense' anagrammed gives 'ESSEN'.
'in' is the link.
(Other definitions for essen that I've seen before include "German place name" , "Industrial city of northwest Germany" , "German industrial city on the Ruhr" , "European city" , "Krupp HQ (Ger.)" .)
