Southern Iceland? (9)
(Other definitions for antarctic that I've seen before include "Of South Polar regions" , "near the south pole" , "Where to pick up a penguin?" , "Area around the South Pole" , "Continent?" .)
'southern iceland?' is the definition.
The answer and definition can be both locations as well as being singular nouns.
Maybe you can see an association between them that I don't see?
This is all the clue.
Can you help me to learn more?
