Wintry comes from Old English wintriġ ('wintry'), from winter + -ig (-y), from Proto-Germanic *wintruz ('winter'). In current use it is an adjective meaning "characteristic of winter; cold, bleak, or unfriendly". That sense is explained by the older material without requiring a speculative semantic step: the inherited or borrowed base supplies the field of meaning, while the English formation fixes its modern role. The surface form is compositional: its joined elements remain visible in the modern word. The historical chain includes Old English winter and Proto-Germanic *wintruz. Related English forms include winter. A derived form is wintriness. The word's history is thus visible in its construction: the components remain interpretable even after the whole expression has settled into a conventional English meaning.
