>>34541252Beartic comes from bear + arctic. The word arctic comes from Greek arktos, meaning bear. The arctic regions of the world are named as such because ursa major and ursa minor are very prominent in the northern hemisphere.
Antarctica is basically anti-arctic or "land with no bears/land with no ursa major or ursa minor".
Arctic got its name from Europeans, and it was only much much later that they became aware polar bears are a thing, and by complete coincidence, they live in the arctic.
