Etymology

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.
