^{page 17 note 1} Professor Skeat writes to me: “The argument about German zu is not to the point. The u in original German thŭ was short. In English it was made long and became thū; and so it became thou, just as hūs became house. But in German it remained short; else the modern word would be dau, just as hus has become haus.”
