Etymology: In ancient Greek, "arktos" simply meant "bear," and the Greeks used it for the animal and for the great constellation we call Ursa Major. Because that constellation wheels around the northern sky, "arktos" became a name for the north, and the adjective "arktikos" meant "northern." English got "arctic" from that adjective through Old French and Latin, so the polar regions carry a bear's name even though bears are not what the word first pointed to. The genus name "Arctos" is a Latinized form of the Greek noun, coined by taxonomists to name a group of bears. It is a scientific label, not an ancient Greek or Roman term for a particular species.
