What does ventilate mean?
Ventilate is chiefly a verb meaning to let fresh air circulate through a room, building, vehicle, or other enclosed space, either by opening windows or by using a mechanical system. It can also mean to express or discuss an issue or opinion openly, especially when a speaker wants a matter aired before others. The literal use is familiar in architecture, engineering, health, and safety contexts; the figurative use tends to sound more formal and journalistic. Ventilation is the result of the action, while a ventilator is the device that provides it. Although ventilate can sound technical, its core idea is simple: move stale or contaminated air out and fresh air in. The word’s history follows that practical idea. It comes through Latin from ventus, “wind,” and its figurative sense extends the same metaphor by suggesting that an idea or grievance should be allowed into the open air. Learning both senses reveals a useful pattern: what is physically aired may also be socially aired.

Where does ventilate come from?
Ventilate entered English in the early 17th century from Latin ventilare, meaning “to fan” or “to ventilate.” The Latin verb was based on ventus, the word for “wind.” English vent and the less common ventose and ventosity also trace their histories to this root.
