Cop rue trio abandoned in Caribbean island? (6,4)
I believe the answer is:
puerto rico
'caribbean island?' is the definition.
(I've seen this before)
'cop rue trio abandoned' is the wordplay.
'abandoned' indicates an anagram (the original order is abandoned).
'cop'+'rue'+'trio'='copruetrio'
'copruetrio' anagrammed gives 'PUERTO RICO'.
'in' is the link.
(Other definitions for puerto rico that I've seen before include "Caribbean location" , "Well-filled country" , "Self-governing American commonwealth in the Caribbean" , "Caribbean island" , "WI island associated with the US" .)
