Etymology and origin of the Latin word caelestis

Confidence
Established
Formation
Derivation
First attested
204–169 BC, Ennius
Ultimate origin
Proto-Indo-European (*keh₂i-lo-)

Pronunciation

  • Classical: [kae̯ˈɫɛs.tɪs][1]
  • Ecclesiastical: [t͡ʃeˈlɛs.tis][1]

Forms

caelestis (neuter caeleste, comparative caelestior, superlative caelestissimus); third-declension two-termination adjective[1] Ovid has an ablative caeleste beside the usual caelestī.[2][3]

Etymology

It is formed from caelum (“sky, heaven”) with the suffix ⟨-estris⟩ of local adjectives, as in its opposite terrestris (“of the earth”), but in the dissimilated form ⟨-estis⟩ of agrestis.[4][2][1] De Vaan traces ⟨caelum⟩ to Proto-Italic *kailo- (“sky”) and Proto-Indo-European *keh₂i-lo- (“whole”).[4]

Earliest recorded meaning

Köbler's first source is Ennius.[5] Varro writes of auspices sent from heaven (auspiciōrum caelestum).[2]

Semantic evolution

It is first what is in or comes from the sky: aqua caelestis is rainwater, caelestis arcus the rainbow, and Cicero says we are nourished by the air of heaven.[2] Signs sent from the sky are divine, and the gods dwell in heaven: Cicero has caelestibus rēbus, “heavenly matters”, set against human ones.[2] Of people and earthly things it means godlike or divine, as Cicero's heavenly legions, and of emperors deified.[2] As a noun, usually plural, caelestēs are the gods, and Horace uses it of a godlike victor.[2] The neuter plural caelestia are heavenly matters.[2]

Church Latin glosses it “heavenly, divine, celestial”, and caelestia “heavenly things, high places”.[6] In medieval Latin it could mean sky-blue.[7] English celestial and French céleste come from it.[8]
