Etymology: Before the word described a machine, "ventilate" meant to fan or blow air through a space, and the Latin root "ventus" means "wind." The English verb "ventilate" came from Latin "ventilātus," the past participle of "ventilāre," meaning to fan or expose to air. From that verb, English formed "ventilator" by adding the agent suffix "-or," so a ventilator was originally whatever did the ventilating: a person or device that circulated air. The suffix took a Latin route of its own. It passed through Old French "-eor" and Middle English "-our" before settling into the modern "-or" spelling, which is why the word carries the same ending as many other agent nouns in English.

Synonyms: fans, air circulators
