Revolution and Revolt

Revolution and revolt have a shared origin, both ultimately going back to the Latin revolvere “to revolve, roll back.” When revolution first appeared in English in the 14th century, it referred to the movement of a celestial body in orbit; that sense was extended to “a progressive motion of a body around an axis,” “completion of a course,” and other senses suggesting regularity of motion or a predictable return to an original position. At virtually the same time, the word developed a sharply different meaning, namely, ”a sudden radical, or complete change,” apparently from the idea of reversal of direction implicit in the Latin verb. Revolt , which initially meant “to renounce allegiance,” grew from the same idea of “rolling back,” in this case from a prior bond of loyalty.
