South Pole region (9)
I believe the answer is:
antarctic
'south pole region' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for antarctic that I've seen before include "Penguin's home" , "Continent?" , "Relating to southern polar region" , "near the south pole" , "Relating to the southern polar area" .)
