Etymology: Latin "serenus" first described the sky rather than a mind. It meant clear, bright, and free of cloud, the way the air looks after a storm has passed. The sense of a calm temperament came later as a metaphor laid over that physical clearness, so a serene face was once imagined as unclouded as a fair sky. Its ultimate origin is uncertain, and etymologists have not firmly linked it to any particular older root. The superlative form, "Serenissimus," became a formal title for rulers. The Republic of Venice styled itself "La Serenissima," and German princely families used "Serene Highness" as a form of address, so a word for clear weather ended up in royal correspondence.
