Forms

ciel m (plural cieux or ciels)[1]

Etymology

It is inherited from Latin caelum (“vault of the sky; abode of the gods; vault, ceiling”), written “celum” and “coelum” in Late Latin.[2][3][4][5][1] The origin of the Latin word is uncertain: it has been linked with caedō (“to cut”), the sky being divided into regions by the augurs, and Wiktionary derives it from a Proto-Indo-European “*keh₂i-lom” “whole”.[3][1] The plural cieux is the old oblique case; the Christian plural “caelī” was modelled on Hebrew “šāmayim”, itself a plural.[6][4][3]

Cognate with Italian cielo, Occitan cel, Catalan cel, Spanish cielo, Portuguese céu and Romanian cer.[7][6]

Earliest recorded meaning

It is first found in the Séquence de sainte Eulalie (about 881), meaning the abode of God and of souls after death.[2][3]

Semantic evolution

The three Latin senses passed into French.[3] The religious one gave, by metonymy, “Providence, God” in par faveur du ciel and the exclamation ô Ciel ! (Montchrestien, 1604), and phrases such as aide-toi, le ciel t'aidera.[2][3] The vault of the sky is in the Vie de saint Alexis (about 1050); until the 16th century les ciels were also the transparent spheres to which the stars were thought to be fixed, whence le septième ciel.[2][8]

The technical sense “vault, ceiling” gave the canopy over a table (after 1350) or a bed, and the roof of a quarry (1676), whence à ciel ouvert “open-air”.[2][3] Bleu ciel “sky blue” dates from 1844.[3] Arc-en-ciel replaced the older arc del ciel (1150–1170).[3]
