Country not welcoming sound (5)
I believe the answer is:
chile
'country' is the definition.
(Chile is a country)
I cannot understand how the remainder of the clue works.
(Other definitions for chile that I've seen before include "Country of S. America" , "Long narrow country" , "S American country, capital Santiago 95)" , "Country liberated by Bernardo O'Higgins" , "Long, thin country" .)
