Unusual gloom in a remote part of Asia (8)
I believe the answer is:
mongolia
'part of asia' is the definition.
(I know that Asia is the is part of of Mongolia.)
'unusual gloom in a' is the wordplay.
'unusual' indicates anagramming the letters.
'gloom'+'in'='gloomin'
'gloomin' anagrammed gives 'mongoli'.
'mongoli'+'a'='MONGOLIA'
'remote' acts as a link.
This may not be right. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for mongolia that I've seen before include "Log Naomi into the vast Asian region" , "Asian country" , "Republic of east central Asia" , "Eastern state" , "Country between China/Russia" .)
