Cold country, by the sound of it (6)
I believe the answer is:
chilly
'cold' is the definition.
(I've seen this before)
'country by the sound of it' is the wordplay.
'country' becomes 'Chile' (Chile is an example).
'by the sound of it' indicates a 'sounds like' (homophone) clue.
'chile' sounds like 'CHILLY'.
(Other definitions for chilly that I've seen before include "Without warmth" , "Cool" , "Quite cold" , "Descriptive of cold weather" , "unwelcoming" .)
