Why this word is great
EXESTUATE — [Verb] To be agitated; to boil up; to effervesce. From Latin exaestuātus, passive participle of exaestuō ("to boil up"), from ex- ("out") + aestuō ("to boil, surge"). Unlike "simmer" (which implies a gentle, steady bubbling) or "seethe" (which suggests internalized rage), "exestuate" is the visible, violent roil of matter in revolt—the geyser’s explosive ascent, the molten rock churning beneath the earth’s crust, or the sudden, irrepressible froth of a shaken soda bottle. It is the world’s refusal to stay still, a reminder that even stillness is only motion waiting to erupt.
