Having fresh air circulated through a space by natural or mechanical means. Can also mean expressed or discussed openly.
From Latin 'ventilatus', past participle of 'ventilare' meaning 'to fan' or 'winnow', from 'ventus' meaning 'wind'. The figurative sense of 'giving expression to' developed in the 18th century.
The word ventilated originally described the ancient practice of winnowing grain by throwing it into the wind to separate wheat from chaff. This agricultural metaphor beautifully captures how fresh air circulation separates good air from stale air, just as wind separates valuable grain from waste.
