Cur barking around European city (9)
I believe the answer is:
rotterdam
'european city' is the definition.
(I've seen this before)
'cur barking around' is the wordplay.
'cur' becomes 'rotter' (I can't explain this - if you can you should give a lot more credence to this answer).
'barking' becomes 'mad' (barking mad).
'around' says the letters should be written backwards.
'mad' backwards is 'dam'.
'rotter'+'dam'='ROTTERDAM'
Can you help me to learn more?
(Other definitions for rotterdam that I've seen before include "European port" , "One of the world's largest ports" , "Major world seaport at the mouth of the Meuse" , "Netherlands port" , "Major North Sea port - tarred tom (anag)" .)
