Men heading down in gloomy country (7)
I believe the answer is:
denmark
'country' is the definition.
(I know that Denmark is a country)
'men heading down in gloomy' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'men' is 'enm' which is located in the answer.
'down' could be 'd' and 'd' is found in the answer.
The remaining letters 'ark' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for denmark that I've seen before include "A country of dark men?" , "Aarhus is its second-largest city" , "Monarchy, a member of the European Union" , "kingdom" , "North European country" .)
