More
  • wind from (Old English):

    A word from an Indo-European root that also gave us Latin ventus, the source of vent (Late Middle English) and ventilate (Late Middle English). Winnow, windwian in Old English, is to use the wind to separate grain and chaff. To get wind of something comes from the idea of hunted animal picking up the scent of a hunter. The phrase wind of change was used by Harold Macmillan, British prime minister 1957–63, during a speech he made in Cape Town in 1960: ‘The wind of change is blowing through this continent, and, whether we like it or not, this growth of [African] national consciousness is a political fact.’ See also ill. For the differently pronounced verb see wand
