Its capital is Yerevan (7)
I believe the answer is:
armenia
'its capital is yerevan' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for armenia that I've seen before include "Transcaucasian nation" , "Republic formerly in the USSR" , "Landlocked country south of Georgia" , "Landlocked country of southwest Asia" , "Former Soviet republic of south-east Europe, capital Yerevan" .)
