German republic (6)
I believe the answer is:
weimar
'german republic' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for weimar that I've seen before include "German town associated with Goethe, Liszt and Schiller" , "German republic until 1933" , "German town giving its name to 1919-33 republic" , "German city; -- Republic" , "German city associated with Liszt and Goethe" .)
