Ether
(n.)
Supposed matter above the air; the air itself.
(n.)
Any similar oxide of hydrocarbon radicals; as, amyl ether; valeric ether.
(n.)
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.
(n.)
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. It is powerful solvent of fats, resins, and pyroxylin, but finds its chief use as an anaesthetic. Called also ethyl oxide.

Ether
Because light consists of waves, the belief that all waves must be channeled through a medium (as sound through air or water) led 19th century physicists to construct ether as the medium supporting the propagation of light. However, the Michelson-Morley Experiment showed that if ether existed it could not be observed. It also demonstrated, more generally, that the construct of a physical medium is inessential for research into communication processes. (Krippendorff)

Aether
Aether, Ether (Greek) [from aitho shining, fire] The upper or purer air as opposed to aer, the lower air; the clear sky; the abode of the gods. In Classical antiquity it denoted primordial substance, Proteus or protyle, the unitary source both of all substances and energies, the mask of all kosmic phenomena. Often used loosely to embrace a domain which extends from the All-Father himself down to the atmosphere of our earth. Vergil speaks of "Jupiter omnipotens aether," and Cicero describes aether as the ultimate zone of heaven encircling, embracing, and permeating all things. At one time a member of the pantheon and object of veneration, at another the quest of the alchemist in search of the "absolute element" which would give him power over nature, and finally a hypothetical medium of science for conveying light waves.
Sometimes aether is used in translating the Sanskrit akasa, which has the same etymological and philosophical meaning. Here it is an element or principle coming after manas and kama and before the astral light and ether. Again, it is a high aspect of akasa, having itself also seven subordinate aspects. There are in kosmic space at least seven aethers or prakritis, which exist one within the other in a rising scale of spirituality. Collectively they may be called spirit-aether or akasa.

Ethereal
Ethereal, Ethereality Used in an attempt to define states of matter more refined and less dense than familiar physical matter. The differences between the higher divisions of matter is analogous to the corresponding subdivisions of physical matter -- solid, liquid, gas, and fiery. Thus the characteristic of the solid is fixity of form, restriction of movement; that of liquid, mobility; of gas, expansibility; while the fiery element among other things is exempt from gravitation. The major divisions of matter must be graded on a somewhat analogous scale.
There is a clear distinction between
1) akasa;
2) the astral light; and
3) ether.
Akasa in its higher portions is pure spirit; the astral light is the seventh or highest division of our physical cosmic plane and may even in a sense be called the most subtle part of the terrestrial atmosphere; whereas ether is a material agent or stuff interpenetrating molecular matter, and is therefore even more gross than is the astral light. In one sense these three are the highest, the very low, and the lowest parts of spirit or akasa itself, the physical stuff or body of our plane being its lees or dregs.

Ether
Ether is the general name for a class of chemical compounds which contain an ether group — an oxygen atom connected to two (substituted) alkyl or aryl groups — of general formula R–O–R'. A typical example is the solvent and anesthetic diethyl ether, commonly referred to simply as "ether" (ethoxyethane, CH3-CH2-O-CH2-CH3).
