Etymology

The word antarctic literally means "opposite of the Arctic." While arctic originates from the Greek word for "bear" (referencing the northern constellations), antarctic was coined to describe the southern polar region as the mirror counterpart. This reflects ancient Greek geographical logic, where the Arctic was the "land of the bear," and the Antarctic, unseen by them, was its theoretical opposite.
