hoffen.

From Middle High German hoffen (12th c.), from northern Old High German *hoffōn, from Proto-West Germanic *hopōn. It is uncertain whether the (unattested but probable) Old High German form was inherited or rather borrowed from Old Dutch hopon with implementation of the High German consonantism (which was then still entirely predictable). In fact, some scholars consider that all continental forms go back to Old English hopian, introduced as a religious term by Anglo-Saxon missionaries. The word was at any rate absent from Upper German, where it only established itself in later Middle High German, gradually displacing the now obsolete gedingen. See English hope for more.
