Forms
serein (feminine sereine, masculine plural sereins, feminine plural sereines)[1] Old French serain, seri, serin and serrin.[2][3] The spelling serein dates from 1549.[3][4]
Etymology
It is inherited from Old French serain, inherited from Vulgar Latin *serānus, an alteration of classical Latin serēnus (“clear, cloudless, calm, peaceful”), according to Rey and the Grand Robert.[3][4][5] The Old French form was respelled ⟨serein⟩ in 1549 after the Latin word.[3][4]
The TLFi and Bloch–Wartburg explain it differently: the commonest medieval form was seri (“mild, calm”) (about 1140 as ⟨serrit⟩), made from the Latin adjective with a change of suffix, and ⟨serein⟩ was later remade on the Latin word.[6][2] The TLFi adds that this Old French form seems to go back to an inchoative verb meaning “to dry”, itself derived from the adjective,[6] which Wiktionary identifies as serēscō (“to become dry”).[1] Bloch and Wartburg note that written Latin may have influenced the word everywhere, especially in its moral sense.[2]
Rey describes the Latin adjective as built on an old stem for the clear, dry state of the sky, and finds its proposed links with other languages unconvincing.[3] Cognate with Italian sereno, Spanish sereno, Occitan seren and Romanian senin.[3][7][8]
Earliest recorded meaning
It is first found about 1170 in Guillaume de Saint-Pair's Roman du Mont Saint-Michel, describing weather that is clear, mild and calm, and as serain in Chrétien de Troyes's Cligès (1176).[6]
Semantic evolution
The first sense, of a pure and calm sky or air, is the Latin one; it is now literary.[3][9] About 1225–1240 Guillaume de Lorris applied the word, as serin, to a look or smile that shows peace of mind.[6][3] In the 16th century it was also used as a masculine noun for clear weather (1538) and for a peaceful face (about 1550).[3]
With an abstract value it came to mean free from agitation (before 1550) and then morally calm, untroubled (before 1648, Voiture).[3][5] In the 20th century it is also said of a social situation.[3] The medical phrase goutte sereine (1611, Cotgrave) named blindness caused by paralysis of the retina, after the popular belief that a clear drop of humour was to blame, since the eye looked unclouded.[6][2]

Usage notes
A separate literary or regional noun serein (the Grand Robert's serein 2, recorded in 1580) names the damp coolness that falls in the evening after a fine day; it continues Old French serain “evening” (12th century), which Bloch and Wartburg trace to Latin sērō (“late”) and the Robert dictionaries to serēnus influenced by Latin sērum (“late hour”).[4][9][2]
