Where men have something to sing about (7)
I believe the answer is:
armenia
'where men have something to sing about' is the definition.
The answer is a location as well as being a singular noun. This is suggested by the definition.
This is all the clue.
Can you help me to learn more?
(Other definitions for armenia that I've seen before include "Landlocked country south of Georgia" , "Former Soviet republic of south-east Europe, capital Yerevan" , "Country in the Caucasus, capital Yerevan" , "Former Russian republic, its capital Yerevan" , "South-west Asian country, capital Yerevan" .)
