Pronunciation

Forms

Etymology

It is formed from Latin serēnus (“clear, unclouded”) + -ō.[2][1][3] The adjective goes back to Proto-Italic *(k)seró- and Proto-Indo-European *Kseh₁-ró- (“dry”).[4]

Earliest recorded meaning

Cicero has the present participle in a fragment of his poem on his consulship, luce serenanti, “in the brightening light”.[5][6]

Semantic evolution

Its main use is poetic.[7] Virgil uses it of a god who clears the sky with his look,[2][5] and then figuratively of a person who puts a hopeful look on their face, spem fronte serenat.[2] Statius uses it of brightening a face,[2] and Silius Italicus of the sky.[7] Minucius Felix uses it impersonally, serenat, “it is fine weather”.[6]
