Where, in Germany, to hear good French? (4)
I believe the answer is:
bonn
'where in germany to hear' is the definition.
The answer is a location as well as being a singular noun. This is suggested by the definition.
'good french?' is the wordplay.
'good' becomes 'bon' (I've seen this in other clues).
'french?' becomes 'n' (I am not sure about this - if you are sure you should believe this answer much more).
'bon'+'n'='BONN'
Can you help me to learn more?
(Other definitions for bonn that I've seen before include "W German capital 1949-90" , "German city" , "old European capital" , "Rhine city" , "Capital of West Germany, 1949-1990" .)
