Show where traffic goes round (6)
I believe the answer is:
circus
'show' is the definition.
(circus is a kind of show)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for circus that I've seen before include "Group of travelling performers" , "Open-air stadium of antiquity" , "All-round entertainment" , "One's named Oxford" , "Trvelling company of entertainers, usually with animals" .)
