Hot country that sounds cold (5)
I believe the answer is:
chile
'hot country' is the definition.
'chile' can be an answer for 'country' (Chile is a country). I am not sure about the 'hot' bit.
'sounds cold' is the wordplay.
'sounds' indicates a 'sounds like' (homophone) clue.
'cold' becomes 'chilly' (I've seen this before).
'chilly' is a homophone of 'CHILE'.
'that' acts as a link.
Can you help me to learn more?
(Other definitions for chile that I've seen before include "S American country, capital Santiago 95)" , "Long, thin country" , "Most southerly American country" , "Country liberated by Bernardo O'Higgins" , "S. American nation" .)
