Etymology: This is an adjective formed from the past participle of "ventilate," so the story belongs to the verb. The root is Latin "ventus," meaning wind, which is also the source of "vent" and "ventilate." Latin "ventilare" meant to fan or blow air across something, and its literal sense was physical: to winnow grain by tossing it in the wind, or to fan a fire. The Latin verb was built from "ventulus," a little breeze, itself a diminutive of "ventus." English borrowed the verb from the past participle "ventilatus" in the Middle English period, when it still carried that concrete sense of setting air in motion. The meaning then widened in the early modern period to cover airing out a room, and eventually to public discussion, as in airing a grievance, which later usages extended further. The adjective "ventilated" describes a space that has been supplied with moving air, which is the older physical sense carried forward. The word's most dramatic shift came from ordinary wind to abstract debate, so the adjective keeps the plainest form of the original idea.
