Relating to Antarctica or the Antarctic region; of or pertaining to the southern polar area.
From 'Antarctic' (from Greek 'anti-' opposite + 'arktos' bear, the constellation) + '-ical' (adjectival suffix). An alternative, more formal variant of 'Antarctic.'
The word 'Arctic' comes from the constellation of the Great Bear, so 'Antarctic' literally means 'opposite the bear'—which is why Antarctica is at the opposite pole from the Arctic!
