Forms
cielo m (plural cielos)[1] Old Spanish texts write it cielo and çielo, more rarely celo and sielo.[2]
Etymology
It is inherited from Latin caelum (“sky, heaven”).[3][4][5][1] Old Spanish had the same form, cielo.[1][2]
The same word is Portuguese céu, Galician ceo, Asturian cielu, Catalan cel, Occitan cèl, French ciel, Italian cielo and Romanian cer.[6][7][1] In Old French, Occitan and Spanish the word also meant a ceiling, and with a word for “mouth” it named the palate in several Romance languages, as in cielo de la boca.[7]
The origin of the Latin word is uncertain.[1] De Vaan reconstructs *kailo- (“sky”), and Wiktionary derives it, with doubts, from *kéh₂i-lom (“whole”), a term of augury for the whole sky as opposed to templum, “the part”.[8][1] An older etymology connected it with the Germanic and Baltic words for “clear”.[8] Varro already derived it from Ancient Greek κοῖλον (koîlon, “hollow”), an explanation Covarrubias repeats and Monlau still followed.[9][10]
Earliest recorded meaning
The Cantar de mio Cid (c. 1140, in a 14th-century copy) has the word in Rodrigo's prayer as he leaves Castile: „A ti lo gradesco, Dios, que cielo e tierra guías” “I thank you, God, who guides heaven and earth”.[11][3]
Semantic evolution
In Alfonso X's prose cielo is the apparent sphere of the sky with its stars, the abode of God and the blessed, and each of the spheres of Ptolemy's astronomy, as in el cielo ochavo.[12] Autoridades (1729) defines it as the region above the elements, then as the heavenly court, and by metonymy as God himself, as in ¡valedme, cielos!.[13] The Academy's edition of 1817 lists the climate of a country, the canopy of a bed or a coach, cielo de la boca “palate” and cielo raso “flat ceiling”.[14]
Modern Spanish also uses cielo as a term of endearment and for a delightful person.[5] In Argentina and Uruguay cielo or cielito is a popular song and dance of the gauchos, named for the word with which its lyrics begin.[15][4]
