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.
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”.
From Old French ether, from Latin aether (“the upper pure, bright air”), from Ancient Greek αἰθήρ (aithḗr, “upper air”), from αἴθω (aíthō, “to burn, shine”). Doublet of Aether.
From Ethereum.
Webster’s 1913
- noun A medium of great elasticity and extreme tenuity, supposed to pervade all space, the interior of solid bodies not excepted, and to be the medium of transmission of light and heat; hence often called luminiferous ether.
- noun Supposed matter above the air; the air itself.
