caelestis

Caelestis, from Latin caelum meaning heaven, is an adjective that means heavenly or celestial, and is used to describe things related to the sky, the divine, or heavenly realms. In classical Latin it describes celestial bodies, gods, or divine attributes; in ecclesiastical Latin it is used to convey sacred or heavenly qualities and often appears in epithet constructions.

Grammatically, caelestis is the masculine and feminine form of a third-declension adjective; the neuter form is caeleste. It can be used attributively, as in caelestis res (heavenly things), or in more formulaic expressions in religious or literary Latin. In later Latin and Neo-Latin, caelestis is also encountered as a proper name or epithet.

In modern usage, caelestis may appear as a given name or surname in neo-Latin or stylistic contexts, and it is sometimes adopted in fiction, branding, or artistic works to evoke celestial associations. It is also used as a species epithet in biological nomenclature to convey a sense of heavenliness or brightness, though such usage is not tied to a particular taxonomic group.
