composure
UK: kəmˈpəʊʒə | US: kəmˈpoʊʒər
n. a state of calmness, self-control, or steadiness of mind
The word "composure" originates from the Latin componere (to put together), via the past participle compositus. The morpheme com- (together) and pos- (place) reflect the idea of "bringing oneself together" or "arranging one's emotions." The suffix -ure (as in "pressure" or "closure") forms a noun indicating a state or condition. Over time, "composure" evolved to specifically denote a calm and collected mental state, emphasizing internal harmony.
