Bananas end up in Germany (7)
I believe the answer is:
potsdam
'germany' is the definition.
Both the definition and answer are singular nouns.
Maybe you can see an association between them that I can't see?
'bananas end up' is the wordplay.
'bananas' becomes 'mad' (slang for insane).
'end' becomes 'stop' (synonyms).
'up' is a reversal indicator (in down clue: letters go upwards).
'mad'+'stop'='madstop'
'madstop' written backwards gives 'POTSDAM'.
'in' is the link.
Can you help me to learn more?
(Other definitions for potsdam that I've seen before include "Site of nineteen forty fve conference" , "Brandenburg capital" , "German city" , "City near Berlin, site of Sanssouci palace" , "Site of WW2 conference" .)
