Diamonds from a town somewhere in Africa (6)
I believe the answer is:
durban
'somewhere in africa' is the definition.
The definition suggests a singular noun which matches the answer.
'diamonds from a town' is the wordplay.
'diamonds' becomes 'd' (abbreviation in bridge say).
'from' says to put letters next to each other.
'a town' becomes 'urban' (urban means relating to a town or city).
'd'+'urban'='DURBAN'
Can you help me to learn more?
(Other definitions for durban that I've seen before include "Kingsmead Cricket Ground city" , "Rub Dan up the wrong way in S Africa" , "Southern port" , "Largest city in KwaZulu-Natal" , "South African city port" .)
