Peru neighbor (5)
I believe the answer is:
chile
'peru neighbor' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for chile that I've seen before include "Country liberated by Bernardo O'Higgins" , "Long, thin country" , "Country of S. America" , "South American country" , "S American country, capital Santiago 95)" .)
