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 German ēther (modern German aether, ether (obsolete), Äther), Spanish éter.[2]

        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.

        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.

2. (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 relativity propounded by Albert Einstein (1879–1955).

     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.

• æther, aether (Britain, dated, obsolete in chemistry)
• aethyr, ethyr (archaic)

From “Ether” (2001), a song by the American hip hop recording artist Nas (born 1973). According to Nas, the song, a diss track aimed at fellow artist Jay-Z (born 1969), was thus named because he was once told that ghosts and spirits do not like the fumes from ether (noun, sense 5), and he viewed the song as affecting Jay-Z in a similar way. The song contains the lines “I fuck with your soul like ether” and “That ether, that shit that make your soul burn slow”.
