Forms

planeta m (plural planetas)[1]

Etymology

It is borrowed from Latin planēta (“planet”), from Ancient Greek πλανήτης (planḗtēs, “wanderer”), a derivative of πλανάω (planáō, “to wander”).[2][3][4][1] The planets were named “wanderers” in contrast with the stars, which seemed fixed.[2][5] The Greek noun is the verb with the agent suffix -της (-tēs).[1] Lewis and Short call the Latin noun a late word, replacing the classical phrases for “wandering stars”.[6]

The same Latin word is Catalan planeta, Portuguese planeta, French planète and Italian pianeta.[7][8][9][1]

The name of the church vestment is the same Latin word: Corominas takes it from Medieval Latin, where it was a name of the chasuble, which Papias explained by its loose, “wandering” skirts.[2][10][11] DICCA-XV instead derives the vestment from Catalan, from the noun Catalan plana.[12]

Earliest recorded meaning

Corominas dates the first record to the Setenario of about 1250.[2][3] The CDH has an earlier passage in the Semejanza del mundo (c. 1223), which explains that the stars that wander in their course have the name planeta in Latin.[13] In Alfonso X's Lapidario it is one of the seven heavenly bodies that were believed to circle the Earth: la planeta que dizen mars “the planet they call Mars”.[14]

Semantic evolution

Old Spanish made the word feminine, as in las siete planetas of the Libro de Alexandre and in the Libro del Acedrex of 1288; the classical authors quoted by Autoridades and the Quijote already treat it as masculine.[2][13] Catalan likewise used it mostly as a feminine in the Middle Ages.[7] In the Libro de buen amor it means “destiny”, a sense that had gone by the time of Covarrubias and Autoridades but lives on in Catalan.[2]

Alfonso X's astrological works speak of watery, masculine and feminine planets.[14] The Diccionario de Autoridades still counted seven planets, Sun, Moon, Mars, Mercury, Jupiter, Venus and Saturn, which gave their names to the days of the week.[15] Terreros noted that some astronomers counted sixteen by adding the satellites of Jupiter and Saturn.[16] The modern definition, a body without light of its own orbiting a star, has replaced the Ptolemaic one, which the 2001 dictionary still kept as a separate sense.[4][17] By antonomasia el planeta is now the Earth.[4]

The sense “chasuble” is recorded from the first half of the 16th century, in Castillejo.[2] In thieves' cant planeta meant “candle”, according to Juan Hidalgo's vocabulary.[15]
