Pronunciation

  • Ecclesiastical: [ˈuː.ra.nus][1]

Forms

Ūranus m sg (genitive Ūranī); second declension[1]

Etymology

It is borrowed from Ancient Greek Οὐρανός (Ouranós), the name of the sky god,[2][3][1] which is the Greek common noun for “sky, heaven”.[1][4]

Earliest recorded meaning

Lactantius uses it for the father of Saturn, the god whom Latin itself called Caelus.[2][3][5]

Semantic evolution

In Latin the name stayed a learned borrowing from Greek myth;[2] Lewis and Short note that the native Latin name for the god was Caelus.[2] In Medieval Latin the common noun uranus was used for the vault of heaven, glossing caelum, and in Ælfric's glossary for the roof of the mouth; the DMLBS also records it in a glossary as the name of a fish, the thornback ray.[6] In New Latin it became the name of the planet Uranus.[1][7]
