European work in Haiti ruined country (8)
I believe the answer is:
ethiopia
'country' is the definition.
(Ethiopia is an example)
'european work in haiti ruined' is the wordplay.
'european' becomes 'e' (abbreviation e.g. EU).
'work' becomes 'op' (abbreviation for opus**).
'in' means one lot of letters goes inside another.
'ruined' indicates anagramming the letters.
'haiti' with letters rearranged gives 'thiia'.
'op' going inside 'thiia' is 'thiopia'.
'e'+'thiopia'='ETHIOPIA'
(Other definitions for ethiopia that I've seen before include "Northeast African country" , "Tie a Hopi up in Africa" , "Where Haile Selassie was once emperor" , "Country formerly called Abyssinia" , "Country of N Africa, capital Addis Ababa" .)
