Strange men in obscure northern country (7)
I believe the answer is:
denmark
'northern country' is the definition.
'denmark' can be an answer for 'country' (Denmark is an example). I am not certain of the 'northern' bit.
'strange men in obscure' is the wordplay.
'strange' indicates an anagram.
'in' means one lot of letters goes inside another.
'obscure' becomes 'dark' (similar in meaning).
'men' with letters rearranged gives 'enm'.
'enm' placed within 'dark' is 'DENMARK'.
Can you help me to learn more?
(Other definitions for denmark that I've seen before include "A country of dark men?" , "kingdom" , "Hamlet, Prince of . . . . . . . (7)" , "EU member" , "Hamlet's homeland" .)
