German industrial city (5)
I believe the answer is:
essen
'german industrial city' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for essen that I've seen before include "Main industrial city of the Ruhr" , "German industrial centre" , "Krupp HQ (Ger.)" , "city in the Ruhr valley" , "German place name" .)
