What is the Difference Between placid, calm, tranquil, and serene?

Like placid, the words calm, tranquil, and serene all mean "quiet and free from disturbance." Calm conveys a quiet composure that contrasts with surrounding chaos, while tranquil suggests a very deep quietude and peace. Serene is loftier still, carrying a sense of utter peace and happiness. Though placid traces back to Latin placēre, meaning "to please," it isn't always as positive a term as its synonyms. It can imply a lack of agitation rather than a true peace, and it sometimes suggests excessive self-satisfaction or even stupidity.
