Son abandoning extremely cold region for a warmer one? (6)
I believe the answer is:
iberia
'son' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for iberia that I've seen before include "Peninsula that was Roman province" , "SW European peninsula" , "European countries" , "W. European peninsula" , "Spain and Portugal - airline" .)
