Etymology

The word "serene" traces back to the Latin serenus, which described clear skies or calm weather. Over time, it evolved metaphorically to describe a tranquil state of mind or environment. The transition from literal clarity (weather) to emotional calmness reflects the human tendency to associate external peace with inner harmony.
