Venezuela neighbor (6)
I believe the answer is:
guyana
'venezuela neighbor' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for guyana that I've seen before include "South American country, a British colony until 1966" , "Country E. of Venezuela" , "South American republic" , "Off the north coast of S. America, the capital is Georgetown" , "Cricket-playing country" .)
