America endlessly razed Black Sea region (6)
I believe the answer is:
crimea
'black sea region' is the definition.
(I've seen this in another clue)
'america endlessly razed' is the wordplay.
I cannot really understand how this works, but
'america' could be 'a' (common abbreviation - e.g. in organisation names) and 'a' is found in the answer.
The remaining letters 'crime' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for crimea that I've seen before include "part of the Ukraine" , "1853-56 war zone" , "Yalta peninsula" , "old war zone" , "Ukrainian peninsula, site of a 19th century war" .)
