Etymology: In ancient Greek, "aither" meant the bright upper air that lay beyond the clouds, the clear sky the gods were thought to breathe. It was linked to "aithein," "to blaze" or "to burn," so the sky was pictured as shining rather than merely empty. Aristotle later treated aether as a fifth element, distinct from earth, water, air, and fire, and said it made up the heavenly bodies, which he believed were unlike anything on the ground. From the Greek adjective "aithērios" came the Latin "aethereus," and the English adjective kept the sense of something belonging to that heavenly realm. Over time it came to describe things that seem too light, delicate, or refined to be fully material. "Aetherial" is an older, more Greek-looking spelling of the more common "ethereal," and both forms descend from the same ancient word for the shining sky.
