Country exchange named before return of kroner (7)
I believe the answer is:
denmark
'country' is the definition.
(Denmark is an example)
'exchange named before return of kroner' is the wordplay.
'exchange' is an anagram indicator.
'before' means one lot of letters go next to another.
'return of' is a reversal indicator.
'kroner' becomes 'kr'.
'kr' in reverse letter order is 'rk'.
'named' is an anagram of 'denma'.
'denma'+'rk'='DENMARK'
(Other definitions for denmark that I've seen before include "Scandinavian country" , "Monarchy, a member of the European Union" , "Hamlet's homeland" , "North European country" , "Copenhagen its capital" .)
