Etymology: "Airless" is a plain compound, built from "air" and the suffix "-less," and the suffix is the older and more interesting half. "Less" traces back through Old English "-lēas," meaning "free from" or "without," which itself descends from a Proto-Germanic root that originally meant "loose" or "free of." That sense of being loosed from something is still visible in the suffix: a "fearless" person is free of fear, and an "airless" room is free of air. "Air" arrived in English from Old French, which had taken it from Latin "āēr," itself borrowed from Greek "āḗr." The Greek word meant the lower atmosphere, the mist and haze between earth and sky, and it is distinct from the "aether," the purer upper air that the Greeks imagined beyond it. English originally used "air" for a broad range of things, including mood and manner, before narrowing toward the breathable gas we mean today.
