Serene
adjective /sɪˈriːn/ — Calm, peaceful, and untroubled
Definition
Characterised by a quality of utter, undisturbed calm — the stillness of a surface with nothing moving beneath it, or the hard-won peace of someone who has found their centre.
Beyond the definition
Not blankness, but settledness. Serenity is peace that has learned to hold itself.
Origin & history
From Latin 'serenus' (clear, bright, unclouded). A serene sky is a clear one — no storm, no agitation, just uninterrupted light.
