Revolutionary travelled across Gold Coast, originally a country (7)
I believe the answer is:
ecuador
'a country' is the definition.
(Ecuador is an example)
'revolutionary travelled across gold coast originally' is the wordplay.
'revolutionary' shows that the letters should be reversed in order.
'travelled' becomes 'rode' (I've seen this in other clues).
'across' is an insertion indicator.
'gold' becomes 'au' ('Au' can be a synonym of 'gold').
'coast originally' becomes 'c' (I am not sure about this - if you are sure you should believe this answer much more).
'au'+'c'='auc'
'rode' enclosing 'auc' is 'rodauce'.
'rodauce' reversed gives 'ECUADOR'.
Can you help me to learn more?
(Other definitions for ecuador that I've seen before include "South American republic" , "South American country, capital Quito" , "South American state" , "The state capital is Quito" , "Where panama hats are made" .)
