Pronunciation

  • IPA (Ecclesiastical): [plaˈnɛː.ta][1]

Forms

planēta m (genitive planētae); first declension[1]

Etymology

It is borrowed from Ancient Greek πλανήτης (planḗtēs, “wanderer, planet”),[2][1][3] from πλανάομαι (planáomai, “to wander”).[4] The OLD treats it with the other form planēs, from Greek Ancient Greek πλάνης (plánēs).[2]

Earliest recorded meaning

Firmicus Maternus uses the plural planētae in his astrology.[5] Köbler dates him 343/350 AD.[3]

Semantic evolution

Lewis & Short note it is Late Latin, used in the plural only, for the classical stellae errantēs “wandering stars”.[5] The TLL also finds mostly the plural.[6] Servius uses it in his commentary on Virgil.[5]

In medieval astronomy the planets were the seven wandering stars, Moon, Mercury, Venus, Sun, Mars, Jupiter and Saturn, and the word was sometimes feminine.[7] In medieval Latin planēta was also a rain cloak worn by laymen and a chasuble.[8][3] English planet is found in late Old English.[4]
