River through Dresden (4)
I believe the answer is:
elbe
'river through dresden' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for elbe that I've seen before include "River flowing through Dresden and Hamburg" , "Dresden and Hamburg's river" , "River rising in the Czech Republic and flowing into the North Sea" , "German banker" , "River of Germany" .)
