ventilación

ventilation
💨🪟 ventilación = vent (air opening) + -ación (the act of) → airing out
Spanish ventilación comes from Latin ventilare, 'to fan, toss in the wind', from ventus, 'wind'. Spot 'vent' at the start: it is the same root as English vent and ventilation. The ending -ación matches English -ation.
