Pronunciation

  • Ecclesiastical: [t͡ʃenˈtaːu̯.rus][1]

Forms

centaurus m (genitive centaurī); second declension[1]

Etymology

It is borrowed from Ancient Greek κένταυρος (kéntauros, “centaur”),[1][2][3] the name of a savage people of Thessaly.[1] The further origin of the Greek word is unclear[3] or disputed.[4]

Ancient scholars explained the name in other ways: Servius derived it from their goading of horses, and Fulgentius from centum (“a hundred”), for a hundred armed horsemen raised by Ixion.[5]

Earliest recorded meaning

It appears in Lucretius[6][2] (96–55 BC)[3] for one of the Centaurs, the race of beings half man and half horse,[7][6] and in Cicero's Aratea[7][6] (81–43 BC)[3] as the name of a constellation.[7]

Semantic evolution

In Classical poetry the Centaurs were the sons of Ixion and a cloud, famous for their battle with the Lapiths;[7][2] Horace calls Chiron the “noble Centaur”.[2][6] The word was also the name of the southern constellation, in Cicero, Hyginus and Manilius,[2][7] and in Virgil of a ship, then treated as feminine,[7][2] and of a ship's figurehead.[2]

Old High German glosses render it with words meaning “half-hound” and “giant”.[3] English took over centaur in the late 14th century.[4]
