Etymology: "Hyperventilating" is a compound built from two Greek-derived pieces, but the second piece arrived in English by a longer route. The prefix "hyper-" comes from Ancient Greek "hupér," meaning "over" or "beyond," which gives the sense of breathing above the normal amount. The main stem traces back through Latin "ventilare," meaning to fan or blow air, from "ventus," wind. A Latin speaker ventilating a room was literally stirring the air with a fan or by opening it to the breeze. English borrowed "ventilate" from Latin in the sense of exposing something to fresh air, and it was only later that the word came to describe the movement of air in and out of the lungs. The medical use of "hyperventilate," with its meaning of breathing excessively fast or deeply, is a modern formation: "hyper-" was attached to "ventilate" in English, so the word describes breathing that exceeds what the body needs.

Synonyms: overbreathing
