Roundabout entertainment (6)
I believe the answer is:
circus
This might be a double definition.
'roundabout' is the first definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'entertainment' is the second definition.
(I know that circus is a type of show)
Can you help me to learn more?
(Other definitions for circus that I've seen before include "Ring entertainment" , "Travelling tent show" , "For example, Oxford" , "Big top entertainment" , "tented area" .)
