Origin & History of “weather”

Weather goes back ultimately to the Indo-European base *we- ‘blow’, which also produced English ventilate and wind. from it were formed two nouns, *wedhrom (source of Russian vedro ‘good weather’) and *wetróm (source of Lithuanian vétra ‘storm’). One or other of these became prehistoric Germanic *wethram, which evolved into German wetter, Dutch weer, Swedish väder, Danish vejr, and English weather. Wither (14th c.) may have originated as a variant of weather, in the sense ‘show the effects of being exposed to the elements’.
