Word History of SKY

English owes a number of words to Old Norse, the language of the Viking raiders and settlers who came to England in the eighth to tenth centuries. The word sky, for example, though it dates to the Middle Ages, has its nearest relatives in modern Scandinavian languages (Danish and Swedish sky, “cloud”) rather than in Old English. Other common words borrowed from Old Norse are crawl, egg, kid, leg, root, seem, take, wing, and wrong.
