serenity
UK: sɪˈrɛnɪti | US: səˈrɛnəti
n. the state of being calm, peaceful, and untroubled
n. a title of honor or respect (archaic, e.g., "Your Serenity")
The word "serenity" derives from the Latin serenus, meaning "clear, calm, unclouded" (originally describing weather). The suffix -ity (from Latin -itas) forms abstract nouns indicating a state or condition. Over time, "serene" evolved metaphorically to describe emotional tranquility, and "serenity" emerged in Middle English (via Old French sérénité) to formalize this abstract quality. The logic mirrors the clarity of a cloudless sky extended to inner peace.
