Latin volvere, "to roll" with the prefix re-, "again" produced revolvere, "to roll back, to turn", which when filtered through French, became the English term revolve in the 14th century; originally, meaning "to change" and only taking on the meaning "orbit" in the late 1600's.

Revolution also came into English via French, in the late 14th century, with the original meaning of "the action of a celestial body moving in an orbit".

Over a period of time, revolution came to mean, "turning around" or "change", and by 1600, it acquired the meaning of "overthrow of the established order".
