Pronunciation

  • Classical: [ˈpɫuː.toː][1]
  • Ecclesiastical: [ˈpluː.to][1]

Forms

Plūtō m sg (genitive Plūtōnis); third declension[1] The Greek form Plūtōn is also used, with the Greek accusative Plūtōna in Horace.[2][3]

Etymology

It is borrowed from Ancient Greek Πλούτων (Ploútōn).[3][1][4] In Greek this is the god of riches, that is, of the stores of grain buried in the earth, a derivative of πλοῦτος (ploûtos, “riches, wealth”),[5] which Beekes derives from πλέω (pléō) as an old word for “flow, multitude”.[5]

Earliest recorded meaning

The first record is in Ennius, who explains that “Pluto in Latin is Dis pater; others call him Orcus”: the god of the underworld of Greek mythology.[2]

Semantic evolution

In Latin poetry and prose he is the king of the underworld, husband of Proserpina and brother of Jupiter and Neptune;[2][3] Virgil, Horace, Seneca and Juvenal name him.[2][3] The adjective Plūtōnius was made from the name.[3]

In New Latin the name was given to the dwarf planet Pluto.[1] English has the god's name from the early 14th century.[6]
