Dragon country (5)
I believe the answer is:
wales
This clue could be a double definition.
'dragon' is the first definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'country' is the second definition.
(country of the UK)
Can you help me to learn more?
(Other definitions for wales that I've seen before include "Part of Great Britain" , "Part of 1" , "UK country" , "Land of Dai and Dylan" , "Principality, part of the UK" .)
