Neighbor of Chile (4)
I believe the answer is:
peru
'neighbor of chile' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for peru that I've seen before include "Machu Picchu country" , "South American country" , "Homeland of Paddington Bear" , "South American republic" , "S American country, capital Lima" .)
