winsome

Etymology

Inherited from Middle English wynsom, winsom, winsome, winsum, wunsum (“beautiful; agreeable, gracious, pleasant; generous; of situations: favourable, propitious”), which came from Old English wynsum (“joyful, merry, pleasant; winsome”), from Proto-West Germanic *wunnjusam (“joyful”). Analysed on the surface, it is winne (“delight, joy, pleasure”) plus -some.
