"In the ninth and tenth centuries the Vikings invaded Britain from Scandinavia and settled in large numbers. Their language, which we call Old Norse, was at least partly comprehensible to the English, who did not hesitate to take over hundreds of words from it: skirt, window, scrub, sky, give, hit, kick, scatter, scrape, skill, scowl, score, fellow, want, skin, knife, law, happy, ugly, wrong and even the pronouns they and them."
