Country set right after early euro trouble (7)
I believe the answer is:
ecuador
'country' is the definition.
(Ecuador is an example)
'set right after early euro trouble' is the wordplay.
'set right' becomes 'r' (common abbreviation. I am not sure about the 'set' bit.).
'after' is a charade indicator (letters next to each other).
'early euro' becomes 'ecu' (European Currency Unit, precursor to the euro).
'trouble' becomes 'ado' (I've seen this before).
'ecu'+'ado'='ecuado'
'r' put after 'ecuado' is 'ECUADOR'.
(Other definitions for ecuador that I've seen before include "Where panama hats are made" , "South American country, capital Quito" , "The state capital is Quito" , "S. American nation" , "South American country on the equator" .)
