What does ethereal mean?
Ethereal is an adjective used to describe things that are extraordinarily light, delicate, or refined — so much so that they seem too beautiful or perfect for the ordinary world. A piece of choral music, a dancer's movement, a landscape veiled in mist, or a fabric that catches the light can all be called ethereal. The word carries strongly positive, admiring connotations, suggesting a quality that transcends the mundane rather than merely pleasing the eye. It also has an older, less common sense meaning 'of the heavens' or 'celestial,' which survives mainly in literary contexts. Derived from the Greek aithērios, meaning 'of the upper air,' ethereal entered English in the sixteenth century. It remains a favorite among writers, critics, and poets precisely because no plainer word captures quite the same blend of fragility, radiance, and unearthly grace.
Extremely light, delicate, and refined in a way that seems too perfect for this world; heavenly or otherworldly.
"The bride wore an ethereal gown of gossamer silk."
Often applied to voices, light, music, fabrics, and physical beauty.
Of or relating to the heavens or the upper regions of the sky; celestial.
"Ancient astronomers placed the fixed stars in the ethereal sphere."
This older, literal sense is now largely confined to literary or historical writing.
Ethereal comes from the Greek word for the pure upper air that the gods were thought to breathe — so when you call something ethereal, you're saying it belongs to heaven more than to Earth.

Etymology of ethereal
Ethereal derives from the Greek adjective aithērios, meaning 'of the upper air' or 'of the bright sky,' formed from aithēr (ether) — the pure, luminous air believed by the ancients to fill the heavens above the earthly atmosphere. The word passed into English in the sixteenth century, likely via Latin aethereus or directly from Greek, initially carrying its literal sense of belonging to the upper regions of the sky before developing its modern figurative sense of delicate, otherworldly beauty. It shares its root with 'ether' itself and with related forms such as 'etherize.'
