Study former currency in this country (7)
I believe the answer is:
denmark
'this country' is the definition.
(I know that Denmark is a Scandinavian country)
'study former currency' is the wordplay.
'study' becomes 'den' (term for a study or office).
'former currency' becomes 'mark' (I have seen 'old currency' mean 'mark' so perhaps 'currency' could also mean 'mark'. I am not sure about the 'former' bit.).
'den'+'mark'='DENMARK'
'in' is the link.
Can you help me to learn more?
(Other definitions for denmark that I've seen before include "EU member" , "Copenhagen its capital" , "A country of dark men?" , "Hamlet's homeland" , "Ditto" .)
