Etymology: "Rotatably" is an adverb built from "rotatable" plus the adverbial suffix "-ly". "Rotatable" itself comes from "rotate," which traces back to the Latin "rotatus," the past participle of "rotare," meaning "to turn like a wheel," from "rota," "wheel." The core idea is therefore a wheel turning around a fixed point, which is still visible in the sense of a part that turns about an axis. The suffix "-ly" does the ordinary work of turning an adjective into an adverb, so "rotatably" describes the manner in which something turns: freely, smoothly, or about its center. Mechanical parts such as a bearing mounted rotatably on a shaft are a typical use, where the word tells you how the movement happens rather than what the object is.
