Great revolutionary circus feature? (3,3)
I believe the answer is:
big top
This could be a double definition.
'great revolutionary circus' is the first definition.
'big top' can be an answer for 'circus' (I've seen this before). I'm not certain of the 'great revolutionary' bit.
'feature?' is the second definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
Can you help me to learn more?
(Other definitions for big top that I've seen before include "'Main circus tent (3,3)'" , "needed by Mae West, for one?" , "performance in The Ring" , "entertainment centre" , "Circus venue" .)
