What does etherealisation mean?
Etherealisation is the process of making something ethereal — giving it qualities of extraordinary delicacy, lightness, airiness, or spiritual elevation, as though it belonged to the heavens rather than the material world. It derives from ethereal, which traces back through Latin to the Greek aithēr, the luminous upper sky of classical cosmology. In modern usage the word appears most often in literary criticism, music writing, aesthetics, and philosophy, where it describes an artist's refinement of raw material into something seemingly weightless or transcendent — a passage of music dissolved into softness, or prose stripped of everything heavy. An older, now largely historical chemical sense referred to converting a substance into ether. Formal and rather rare in everyday speech, etherealisation always carries an uplifting connotation, implying the shedding of gross physicality in favour of grace and purity. It should not be confused with etherization, which concerns ether as an anaesthetic agent.
nounThe process or result of making something ethereal — that is, extremely delicate, light, and airy, or refined to a heavenly or otherworldly quality. In older chemistry, it also denotes the conversion of a substance into ether.
- The act or process of making something ethereal: extremely refined, delicate, light, or heavenly in quality.
- (Chemistry, chiefly historical) The conversion of a substance into ether, or treatment with ether.
"The composer's orchestration achieved a remarkable etherealisation, dissolving the melody into shimmering threads of sound."
"Critics praised the ballet's etherealisation, as the dancers seemed barely to touch the stage."
"Nineteenth-century chemists described the etherealisation of alcohol in their treatises on ether synthesis."
Usually uncountable, referring to the process in general; the plural is uncommon and used only when counting distinct instances of such refinement.
"The exhibition traced various etherealisations of landscape across two centuries of painting."
Trace it back far enough and etherealisation comes from Greek aithēr — the pure, bright upper air the ancients believed gods breathed, far above our ordinary atmosphere.

Etymology of etherealisation
Etherealisation is formed from the adjective ethereal plus the noun-forming suffix -isation, following the regular pattern by which English adjectives become abstract nouns. Ethereal itself entered English via Latin aethereus from Greek aithērios, derived from aithēr, the bright upper air or sky of ancient cosmology. The related verb etherealize (British etherealise) arose later, and etherealisation is its action noun. The American spelling etherealization uses -z-, reflecting Noah Webster's reforms.

A formal, literary word, more at home in criticism, aesthetics, and philosophy than everyday speech. The spelling with -s- is standard in British English; American English typically uses etherealization. It carries a positive, elevating connotation, suggesting transcendence of the mundane.
Easily confused with etherealisation
Etherization refers specifically to the medical administration of ether as an anaesthetic (or its chemical conversion into ether), whereas etherealisation means rendering something delicately light, airy, or spiritually refined.
Etherealization is simply the standard American spelling of the same word, using a z rather than the British s.
