sereno

Forms

sereno (feminine serena, masculine plural sereni, feminine plural serene, superlative serenissimo)^[1]

Etymology

It is inherited from Latin serēnus (“clear, unclouded”), a word used of the sky and figuratively for a calm mind.^[2][3][4][1] The word is panromance: French serein, Occitan seré, Catalan seré, Spanish sereno, Portuguese sereno, Sardinian serenu and Romanian senin.^[3][5]

DELI and the Treccani dictionary take the original sense of the Latin word to be “dry”, which gave “free of clouds”.^[2][6] De Vaan reconstructs Proto-Italic *(k)seró- “dry” and connects it with Ancient Greek ξηρός (xērós, “dry, arid”) and Old High German serawēn (“to dry out”), through an unrecorded stative verb meaning “to be dry” that also underlies serēscō (“to become dry”).^[7] Nocentini and DEI give the same comparison, DEI with a cautious “perhaps”, and Wiktionary calls the origin uncertain.^[3][8][1]

Earliest recorded meaning

DELI dates the first record to about 1224, in Francis of Assisi, with the sense “clear, free of clouds and wind”; the line praises God “for air and cloud and clear sky and every weather” (per aere e nubilo e sereno et onne tempo).^[2][9]

Semantic evolution

The figurative sense “quiet, untroubled by care” appears before 1306 in Iacopone da Todi.^[2][4] Used as a noun, sereno meant “clear sky, fair weather” in Dante and “the open air” in Boccaccio, who also used it for the cold night air.^[2][4] Dante and Petrarch used it for the brightness of the sky and of a gaze.^[4][10]

The superlative serenissimo became a title of princes in Giovanni Villani, and serenità a form of address to rulers in a Venetian document of 1486;^[2] serenissima republica named the Republic of Venice in Paolo Sarpi.^[2] The sense “impartial” is recorded only from 1922.^[2] In the southern dialects and in Sardinian the word came to mean the evening dew or frost, as French serein means nightfall.^[8] German took sereno as a musical direction in 1839.^[11]

Usage notes

A ciel sereno means “in the open air”, and fulmine a ciel sereno, a bolt from a clear sky, is a sudden and usually unwelcome event.^[14][12] DEI records a separate 19th-century Piedmontese sereno, a rural watchman who called out the state of the sky at dawn, named from that cry and perhaps taken from Spanish, where the night watchman has the same name.^[8]
