A classical physical element, considered as prevalent in the heavens and inaccessible to humans. In some versions of alchemy, this was the fifth element in addition to air, earth, fire and water
the fifth and highest element after air and earth and fire and water; was believed to be the substance composing all heavenly bodies
a medium that was once supposed to fill all space and to support the propagation of electromagnetic waves
(Pronounced ith-er) - heavenly substance said to be the origins of both energy and matter on the plane of the physical, a mystical element Sorcerors and Wizards may tap to gain powers such as telepath, telekenisis, and transfiguration of energy/matter (I E Teleportation, Synthesis of objects from thin air ETC)
a colorless volatile highly inflammable liquid formerly used as an inhalation anesthetic
A light, volatile, mobile, inflammable liquid, (C2H5)2O, of a characteristic aromatic odor, obtained by the distillation of alcohol with sulphuric acid, and hence called also sulphuric ether
A light volatile flammable liquid (C4H10O) used chiefly as a solvent and anaesthetic
A substance (aether) once thought to fill all space that allowed Electromagnetic waves to pass through it and interact with matter, without exerting any resistance to matter or energy (disproved by Einstien in his Theory of Relativity)
Ether is a colourless liquid that burns easily. It is used in industry and in medicine as an anaesthetic. a sweetish smell of ether and iodine. Any of a class of organic compounds whose molecular structure has an oxygen atom interposed between two carbon atoms that are part of hydrocarbon molecules. Ethers have the general chemical formula ROR, in which R and R represent the hydrocarbons. They resemble alcohols but generally are less dense, less soluble in water, more volatile, and more inert. They are used in chemical processing, for extraction and separation of chemicals, and as solvents. Some are used as insecticides and soil fumigants. They are also used in medicine and pharmacology. Codeine is the methyl ether of morphine. The term ether often refers to ethyl ether (C2H5OC2H5), best known as an anesthetic but also used as a solvent, an extractant, and a reaction medium
A molecule containing a C-O-H double bond to another O, making this part of an ester linkage, or some other exception holds
