Etymology
Etymology tree Proto-Indo-European *h₂eydʰ-der. Proto-Hellenic *áitʰō Ancient Greek αἴθω (aíthō) ▲ Ancient Greek ᾱ̓ήρ (āḗr)influ.? Ancient Greek αἰθήρ (aithḗr)der. Latin aethērder. English ether 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”), 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 New 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”), 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), German Äther, Ether, Portuguese éter, Spanish éter.

In barely the blink of an eye, the perfectly healthy Judy entered a permanent vegetative state. […] What haunted me was the idea that one moment you’re gazing at your 2-year-old in her playroom and the next, you, the mother, have been whisked off into the ether forever.
2009 December, Sandra Tsing Loh, “On Being a Bad Mother: True Confessions”, in The Atlantic, →ISSN, archived from the original on 25 Jul 2018:Take a snapshot of the conflicts around the world: Sunnis vs. Shiites, Israelis vs. Palestinians, Serbs vs. Kosovars, Indians vs. Pakistanis. They seem to be driven by religious hatred. It’s enough to make you wonder if the animosity would melt away if all religions were suddenly, somehow, to vanish into the ether. But James Carse doesn’t see them as religious conflicts at all. To him, they are battles over rival belief systems, which may or may not have religious overtones.
2008 July 21, Steve Paulson, “Religion is Poetry”, in Salon, archived from the original on 30 Aug 2017:There’s a very real chance that, rather than crumbling into the dust and floating off into the ether, Thanos’s victims [in the film Avengers: Infinity War] were actually sucked up into the Soul Stone.

(historical, uncountable) Often as aether and more fully as luminiferous aether: The hypothetical substance permeating space, functioning as a medium for electromagnetic waves to propagate through, and which does not exert resistance to the movement of matter; its existence is incompatible with Einstein's theory of relativity; famously found to be undetectable by the 1887 Michelson–Morley experiment.
"The ether. The earth browses upon a circular path in the fields of space, and as it moves the ether is continually pouring through it and providing its vitality."
1929, Sir Arthur Conan Doyle, When the World Screamed:I ſuppose this æther pervades all groſs bodies, but yet ſo as to ſtand rarer in their pores than in free ſpaces, and ſo much the rarer, as their pores are leſs. And this I ſuppose (with others) to be the cauſe, why light incident on thoſe bodies is refracted towards the perpendicular; […] I ſuppose the rarer æther within bodies, and then denſer without them, not to be terminated in a mathematical ſuperficies, but to grow gradually into one another; […]
1679 February 28, Thomas Birch, quoting Isaac Newton, “The Life of the Honourable Robert Boyle. [Letter from Isaac Newton to Robert Boyle.]”, in Robert Boyle, The Works of the Honourable Robert Boyle. In Five Volumes. To which is Prefixed the Life of the Author, volume I, London: Printed for A[ndrew] Millar, […], published 1744, →OCLC, page 70:Having ſhewn how the Æther cauſes a great part of the Phænomena of Nature, it may be aſked, whence this general material Cauſe has its great Activity and Power? […] This Cauſe muſt be either Matter or Spirit, there being nothing in the Univerſe, which we know if, beſides theſe two. But this Cauſe cannot be Matter: for Matter is in own Nature inert, and has not any Activity in itſelf; and conſequently cannot communicate any Power to the Æther. And therefore the Cauſe, which gives the Æther its Activity and Power, muſt be Spirit. Spirit, which intercedes the Particles of Æther, and gives them a repulſive Power, and ordains and executes the Laws, by which Æther and Bodies act mutually on one another, muſt be preſent in all Parts of Space, where there is Æther.

[…] The latter, æther, is a ſubtile elaſtic fluid, whoſe particles have a continual tendency to ſeparate or fly off every way, unleſs impreſſed by ſome body: This æther ſurrounds each atom like an atmoſphere, and preſſes equally towards the center of each.

Now we are liberal with our innermost secrets, spraying them into the public ether with a generosity our forebears could not have imagined. Where we once sent love letters in a sealed envelope, or stuck photographs of our children in a family album, now such private material is despatched to servers and clouds operated by people we don't know and will never meet.

[…] I allude to the æthers formed by the union of fatty acids with different alcohols. […] With regard to the fatty æthers themselves, I prepared them generally by M. Berthelot's method, by heating the alcohol and the acid for a day at 392°F. in a tube hermetically sealed; the product was mixed with a little æther, and it was digested some time with slaked lime in the water-bath, to separate the free acid from the neutral compound.
1858 October 15, M. Hanhart, “On Some New Æthers of Stearic and Margaric Acids”, in William Francis, editor, The Chemical Gazette, or, Journal of Practical Chemistry, in All Its Applications to Pharmacy, Arts and Manufactures, volume XVI, number CCCLXXXIV, London: Published by Taylor and Francis, […], page 384:When chlorine gas is passed in excess through salicylic ether (salicylae of ethyl) heated over a water-bath, a solid substance is formed which is soluble in hot alcohol, and crystallizes, on cooling, in beautiful colourless tables. This compound is bichloruretted salicylic ether, formed from salicylic ether (C₁₈H₁₀O₆) by the substitution of 2 eq. chlorine for 2 eq. hydrogen: its composition is therefore C₁₈H₈Cl₂O₆.
1851, A[uguste André Thomas] Cahours, “[Notices of Papers Contained in the Foreign Journals.] On Anisol and Phenetol”, in Henry Watts, editor, The Quarterly Journal of the Chemical Society of London, volume III, London: Hippolyte Bailliere, […]; Paris: J. B. Baillière, […]; Madrid: Bailly Baillière, […], →OCLC, page 78:M. Malaguti finds that dry chlorine, while acting in the dark upon oxacid æthers, always attacks, and in a uniform manner, the sulphuric æther which is the base of them. […] The action of potash on the compound chloridized æthers is also constant and uniform: the results are always chloride of potassium, acetate of potash, and an organic salt with a base of potash, the acid of which is that which existed in the compound chloridized æther.
1838 March, “Action of Chlorine on Æthers”, in David Brewster, Richard Taylor, Richard Phillips, editors, The London and Edinburgh Philosophical Magazine and Journal of Science, volume XII (3rd Series), number 74, London: Printed by R[ichard] and J[ohn] E[dward] Taylor, […], →OCLC, page 297:An old man to whom a few drops of phosphoric ether had been administered experienced repeated and imperious venereal wants.
