Revolve is formed from "re-" (meaning again) and "volvere" (meaning to roll). The word describes the action of rolling around again, as in orbiting or turning around a central point.
Think of something rolling 'again' ('re-') around a center ('volvere') — that's why revolve means to turn around something.
