Notes: You probably know this word, as I did, but I was unaware of the background
The word serein means “a fine rain falling after sunset from a sky in which no clouds are visible”
Our word came into English in the mid-1800s
Background / Comments
Our word came from the French word serein, which came from the Middle French word serain (evening; nightfall). This word came from the Latin word sērum (a late hour), which is the neuter form of sērus (late). I don’t think I’ve ever seen a serein, but after sunset, it is hard to see clouds in the sky.
