Rotate, revolve (6)
I believe the answer is:
gyrate
I believe this clue is a double definition.
'rotate' is the first definition.
(I know that gyrate is a more specific form of rotate)
'revolve' is the second definition.
(I know that gyrate is a more specific form of revolve)
(Other definitions for gyrate that I've seen before include "Spin round" , "Move rapidly in a circle" , "Turn" , "Spiral about a point" , "Move around in circles, revolve" .)
