City on the Black Sea (5)
I believe the answer is:
yalta
'city on the black sea' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for yalta that I've seen before include "Crimean resort city" , "City on the Black Sea, where Roosevelt, Stalin and Churchill met in 1945" , "Black Sea resort" , "Black Sea port" , "Crimean town famous for WW2 conference" .)
