ventilation
ven-tih-LAY-shun
/ˌventɪˈleɪʃən/
The provision of fresh air to a room, building, or enclosed space; the circulation and exchange of air.
Implies a deliberate, designed system or process of air exchange, rather than accidental drafts.
The story behind the word. Ventilation traces back to the Latin word 'ventus', meaning wind. Ancient farmers used 'ventilation' when winnowing grain—throwing it into the air so the wind would blow the useless chaff away, leaving only the heavy wheat.
Word relationships
- aeration: Aeration usually refers to exposing soil, water, or liquids to air, whereas ventilation refers to rooms and buildings.
- air circulation: Air circulation is the movement of air within a space, while ventilation specifically requires bringing in fresh air from outside.
- stagnation: Stagnation is the complete lack of air movement or exchange.
Commonly confused with
- respiration: Respiration is the biological process of breathing at the cellular or organism level; ventilation is the physical movement of air in a space.
Word family
- ventilate (verb): To cause fresh air to enter and circulate through a space.
- ventilator (noun): An appliance or machine for ventilating a room, or a medical device that helps a patient breathe.

Memory hook
Think of a 'vent' letting the 'wind' (ventus) blow through. Ventilation keeps the air moving. Vents bring the wind for ventilation.
When not to use
Do not use when you simply mean a breeze or wind outside; ventilation is almost always used in relation to enclosed spaces.
Fun facts
- In the 19th century, British hospitals realized that simply opening windows to improve ventilation reduced patient mortality rates dramatically long before antibiotics were discovered.
