Getting a shock when you go round (4)
I believe the answer is:
turn
'go round' is the definition.
(both can mean to rotate)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for turn that I've seen before include "Change direction" , "Spell" , "Twist; go" , "Change one's mind" , "revolutionary act" .)
