Etymology: The name describes the bird's feet. In Ancient Greek, "lagṓpous" was a compound of "lagṓs", meaning "hare", and "poús", meaning "foot", so it literally meant "hare-footed." The ptarmigan and its relatives grow dense feathering over their toes in winter, which gives the foot a soft, furred look much like a hare's, and that resemblance is what the name records. The Greek compound passed into Latin as "lagōpūs," and the Latin form is the direct source of the English word. Ancient naturalists used the Greek and Latin terms for the same kind of bird, so the name has been attached to these northern grouse-like birds for more than two thousand years. The English word keeps the Latin form and its Greek roots intact, and its sibling words "lagopod" and "lagopode" follow the same pattern, all meaning "hare-footed." Only the foot is named here, not the bird's whole body, so the word is a reminder of one feature that struck observers most.
