From Middle English ēther (“the caelum aetherum of ancient cosmology in which the planets orbit; a shining, fluid substance described as a form of air or fire; air”),[1] borrowed from Anglo-Norman ether and Middle French ether, ethere, aether, from Old French aether (“highest and purest part of the atmosphere; medium supposedly filling the upper regions of space”) (modern French éther), or directly from its etymon Latin aethēr (“highest and purest part of the atmosphere; air; heavens, sky; light of day; ethereal matter surrounding a deity”) (note also Late Latin aethēr (“chemical compound analogous to diethyl ether”)), from Ancient Greek αἰθήρ (aithḗr, “purer upper air of the atmosphere; heaven, sky; theoretical medium supposed to fill unoccupied space and transmit heat and light”),[2][3] from αἴθω (aíthō, “to burn, ignite; to blaze, shine”), from Proto-Indo-European *h₂eydʰ- (“to burn; fire”).
The English word is cognate with Italian ether, ethera (both obsolete), etere, Middle Dutch ether (modern Dutch aether (obsolete), ether), Middle High Germanēther (modern German aether, ether (obsolete), Äther), Portuguese éter, Spanish éter.[2]

(by extension) The medium breathed by human beings; the air. [ quotations ▼]
(by extension) The sky, the heavens; the void, nothingness. [ quotations ▼]
(uncountable, physics, historical) Often as aether and more fully as luminiferous aether: a substance once thought to fill all unoccupied space that allowed electromagnetic waves to pass through it and interact with matter, without exerting any resistance to matter or energy; its existence was disproved by the 1887 Michelson–Morley experiment and the theory of relativitypropounded by Albert Einstein (1879–1955). [ quotations ▼]
(uncountable, colloquial) The atmosphere or space as a medium for broadcasting radio and television signals; also, a notional space through which Internet and other digital communicationstake place; cyberspace. [ quotations ▼]
(uncountable, colloquial) A particular quality created by or surrounding an object, person, or place; an atmosphere, an aura. [ quotations ▼]
