serene

Etymology

It is inherited from Middle English serene,^[2] borrowed from Latin serēnus (“clear, fair, calm (of weather); peaceful, cheerful”),^{[3][4][5][6][7]} partly also through Old French serein, as the MED and Etymonline note.^[2][4] The Latin adjective is also the source of serein, sereno, sereno and sereno.^[3][8] Klein calls its origin uncertain and compares Ancient Greek ξηρός (xērós, “dry”) and Old High German serawēn (“to become dry”);^[9][7] Barnhart, more cautiously than Etymonline, derives it from Proto-Indo-European *ksero- (“dry”).^[6][4] The verb serene (1613) is from serēnō (“to make clear”), and the noun serene, a calm expanse, from the neuter serēnum.^[3][7]

Earliest recorded meaning

Of a day, clear, bright and fair: about 1440, in the Middle English translation of Palladius on husbandry.^[2][6] The OED's first record is from 1508, in Dunbar's Goldyn Targe, of the weather or sky as clear, fine and calm,^[3] and Hoad notes that both early senses are first found in Scots.^[8]

Semantic evolution

The word began as a term for weather and sky, as in Latin, and was soon also an honorific epithet of princes, "most serene", which Barnhart dates to 1503 in Dunbar's poems^[6] and the OED to before 1550.^[3] The sense "calm, untroubled" was transferred to people, minds and faces in the 17th century: the OED's first quotation is from Fuller in 1640,^[3] Barnhart has it before 1635^[6] and Etymonline from the 1630s.^[4] Johnson (1755) gave "calm; placid; quiet" first, with Milton's "calm and serene air", and "unruffled; undisturbed" second.^[10] Poetry used it of the shining moon and stars (1709, Pope) and of colours (1751, Gray's Elegy),^[3] and Milton's drop serene (1667) renders the medical Latin gutta serena, a kind of blindness.^[3] The phrase all serene, "all's well", was street slang of the 1850s: Weekley quotes Hotten (1859) calling it a phrase of very recent use and the refrain of a song,^[11] and the OED has it from 1856.^[3]

Usage notes

A different, obsolete noun serene (1591–1682) meant a fine, supposedly harmful dew or mist falling after sunset in hot countries; it has a separate source, French serein, from Latin sērus (“late”), and was confused with the adjective in French.^[3][14][7]
