돌리다 is making something turn — a wheel spun without looking, a skipping rope turned by two people, a person swung round by the feet. It is also how you say running a machine: 전자레인지에 넣고 돌리기만 한다던가 (just put it in the microwave and run it). 돌려 말하다, in one line, is talking round something instead of saying it straight.
