What does empyrean mean?
The empyrean is, in classical and medieval cosmology, the highest heaven — the outermost sphere of the universe, imagined as a region of pure fire or light beyond which lay only the divine. The word comes ultimately from Greek 'empyros', meaning 'in fire', reflecting the ancient belief that this supreme celestial realm was composed not of ordinary air but of radiant elemental flame. In modern English, 'empyrean' is chiefly a literary noun referring to the heavens, the vault of the sky, or any supremely exalted place or state. It can also function as an adjective describing something celestial, sublime, or soaringly lofty, as in 'the empyrean heights'. Because of its grandeur and rarity, the word lends writing an elevated, almost sacred register: poets use it for skies filled with light, and essayists reach for it when describing transcendent ambition or experience. To rise 'into the empyrean' is to ascend, whether bodily, spiritually, or imaginatively, to the very top of things.
The highest part of the heavens, conceived in ancient and medieval cosmology as a sphere of pure fire or light; more broadly, the heavens or the most exalted realm.
"Milton placed the throne of God in the empyrean, high above the created spheres."
Often preceded by 'the'. Frequently figurative in modern usage, denoting any supremely elevated place or state.
Of or relating to the empyrean; supremely lofty, sublime, or celestial.
"The cathedral's spire reached toward the empyrean vault above."
Rarely pluralized; the noun is usually treated as singular since it names a single unique realm. A plural may appear when contrasting multiple imagined or depicted heavens.
"Different traditions imagined different empyreans, each the seat of its own divine order."
The word 'empyrean' literally means 'in-fire' — the ancients believed the outermost heaven was made of pure burning light, so heaven itself was thought to be on fire.

Etymology of empyrean
Empyrean derives from the Greek adjective 'empyros', formed from 'en-' (in) and 'pyr' (fire), hence 'in fire'. Ancient Greek cosmographers applied it to the sphere of pure fire believed to surround the universe at its uppermost limit, and medieval writers inherited the term through Latin 'empyreus' to name the dwelling place of God and the blessed. The word entered English in the early seventeenth century, initially as a noun denoting this fiery highest heaven, and later developed its adjectival sense. It shares the Greek root 'pyr' with words such as 'pyre', 'pyrotechnics', and 'empyreal'.
