Etymology
Origin of ventilation
1425–75; late Middle English ventilacioun < Latin ventilātiōn- (stem of ventilātiō ), equivalent to ventilāt ( us ) ( see ventilate) + -iōn- -ion
Explanation
Ventilation is when you let fresh air into a place, or air a room out. If you've ever been in a stuffy, hot room and said, "Someone open a window!" you know what it meas to need ventilation. Ventilation airs out an indoor space by letting fresh air in and stale or smelly air out, and it's more effective if you open several windows on opposite sides of the house or building. A fan in the window can also aid ventilation. The root word is the Latin ventulus, "a breeze," which comes from ventus, "wind."
