Spin, circulate (6)
I believe the answer is:
rotate
I believe this clue is a double definition.
'spin' is the first definition.
(I know that spin is a kind of rotate)
'circulate' is the second definition.
(thesaurus)
(Other definitions for rotate that I've seen before include "Turn around as on axle or spit" , "Turn around an axle, swivel" , "Move round centre" , "wheel" , "Alternate" .)
