Poles sounding out German city (5)
I believe the answer is:
essen
This clue might be a double definition.
'poles sounding out german' is the first definition.
The definition and answer are not the same part of speech. However, I know that 'german' relates to this answer.
'city' is the second definition.
(Essen is an example)
Can you help me to learn more?
(Other definitions for essen that I've seen before include "city in the Ruhr valley" , "German industrial centre" , "German place name" , "European city" , "Krupp HQ (Ger.)" .)
