Pronunciation

  • Brazil: /plaˈne.tɐ/[1]
  • Portugal: /plɐˈne.tɐ/[1]

Forms

planeta m (plural planetas)[1] 15th-century texts also write preneta and pranetas, and perneta is recorded between 1450 and 1516.[2] Nascentes quotes praneta from the Inéditos de Alcobaça.[3]

Etymology

It is borrowed from Latin planēta (“planet”), from Ancient Greek πλανήτης (planḗtēs, “wanderer”), from πλανάω (planáō, “to wander, stray”).[2][4][5][1] Houaiss calls the Latin word Late Latin and also names πλάνης (plánēs), the form the OLD equates with it; the Greek name meant “wandering stars”, so called because the planets move against the fixed stars.[2][6][5][7] Nascentes calls it a learned word, and Wiktionary a learned borrowing already in the old language, Old Galician-Portuguese planeta.[5][1] The origin of the Greek verb is unknown.[1]

The same Latin word is Galician planeta, Spanish planeta, first recorded about 1250, and French planète, recorded from 1119.[8][7][9] The noun is masculine in Greek and in classical Latin, but feminine in Isidore; it was feminine in Old Galician-Portuguese and Old Spanish as well, and became masculine again in the modern literary language.[3][7]

Earliest recorded meaning

Houaiss dates the word to the 13th century, from a cancioneiro.[2] In a cantiga of Estevan da Guarda, Martin Vaasquez loses faith in astrology polo grand'engano / dos planetas “through the great deceit of the planets”, and the same poem says that as planetas drove him mad, with the noun in both genders.[10][11] The Crónica Troiana speaks of the stars et as planetas that revolve and shine.[11]

Semantic evolution

In the Middle Ages the planets were above all the bodies of astrology, believed to rule a person's fate: Nascentes quotes as pranetas lho outorgarom from the Leal Conselheiro, and Aulete still records ter nascido debaixo de bom planeta “to have been born under a good planet”, to be lucky in everything, an allusion to that belief.[3][12] Vieira quotes Garcia de Resende on the seven jousters of Duke Manuel, who came “with the seven planets”.[13]

Morais's dictionary of 1813 defines the planet as a body that shines only by the light of the Sun, distinguishes superior and inferior planets, and lists the chasuble as a figurative sense.[14] In the modern language o planeta is also the Earth.[2][15] Dialect surveys in Brazil have recorded the word for a shooting star.[16]

Timeline

  • 13th century – first record, in a cancioneiro.[2]
  • 1300 – first record of the Old Galician-Portuguese word according to Wiktionary.[1]
  • 15th century – the spellings preneta and pranetas.[2]
  • 1450–1516 – the form perneta.[2]
  • 1611 – Barbosa renders Planeta by Latin planeta and sidus.[17]
  • 1755 – Folqman enters the word as masculine.[18]
  • 1813 – Morais adds the chasuble as a figurative sense.[14]
  • 1899 – Figueiredo's dictionary has the feminine planeta “chasuble”.[2]

Usage notes

Houaiss, Aurélio and Priberam record a feminine planeta, pronounced with open /ɛ/, for the chasuble of a priest; it is from Ecclesiastical Latin planeta, probably, Houaiss suggests, by association with the planet, as the vestment could turn around the person who wears it.[2][15][19] Houaiss dates it to Figueiredo's dictionary of 1899, though Morais had already listed it in 1813, and Medieval Latin used the word for a rain cloak worn by laymen and for the chasuble.[2][14][20]
