Land of men in song (7)
I believe the answer is:
armenia
'land' is the definition.
The answer and definition can be both locations as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'men in song' is the wordplay.
'in' is an insertion indicator.
'song' becomes 'aria' (piece of music in an opera).
'men' inserted inside 'aria' is 'ARMENIA'.
'of' is the link.
Can you help me to learn more?
(Other definitions for armenia that I've seen before include "Landlocked country south of Georgia" , "Caucasian republic" , "Republic, formerly part of the Soviet Union" , "Mountainous republic bordering Turkey" , "Republic east of Black Sea bordering Turkey, capital Yerevan" .)
