Travelling company round about, not all American (6)
I believe the answer is:
circus
This might be a double definition.
'travelling company' is the first definition.
'circus' can be an answer for 'company' (circus is a kind of company). I'm not certain of the 'travelling' bit.
'round about not all american' is the second definition.
'circus' can be an answer for 'round' (thesaurus). I'm not sure about the 'about not all american' bit.
Can you help me to learn more?
(Other definitions for circus that I've seen before include "All-round entertainment" , "Open space where streets meet" , "Street formed in a circle" , "For example, Oxford" , "Carnival" .)
