We have a hard enough time remembering which one is the Arctic and which one is the Antarctic, and that's long before we start the process of trying to figure out how to pronounce them. We just looked it up to confirm it, and the Arctic is the North Polar region, with the Antarctic being down the opposite side of the globe.
If it's easier, think of a polar bear on top of a penguin - trust us, we're going somewhere with this odd analogy. Polar bears life up at the North Pole, and penguins are closer to the Antarctic (although they don't really live on or around the South Pole, that's a popular modern-day myth). That word "Antarctic", by the way, has two 'c's, so make sure you pronounce them both. It's "Ant-ark-tik", not "Ant-artik".
