Did you know?

If you're burning to know the history of ethereal, you're in the right spirit to fully understand the word's etymology. The ancient Greeks believed that the Earth was composed of earth, air, fire, and water, but that the heavens and its denizens were made of a purer, less tangible substance known (in English transliteration) as either quintessence or ether. Ether was often described as an invisible light or fire; its name comes from the Greek verb aithein, meaning "to ignite" or "to blaze." When ethereal, the adjectival kin of ether, debuted in English in the 1500s, it described regions beyond the Earth or anything that seemed to originate from them.
