Rotate; go (4)
I believe the answer is:
turn
This clue is a double definition.
'rotate' is the first definition.
(I've seen this before)
'go' is the second definition.
(as in one's go or turn in a game)
(Other definitions for turn that I've seen before include "Distinctive expression" , "Move in a new direction" , "Revolution by runt" , "See 19" , "change for Autumn" .)
