Circus home of huge spinner (3,3)
I believe the answer is:
big top
'circus' is the definition.
(I've seen this before)
'huge spinner' is the wordplay.
'huge' becomes 'big' (similar in meaning).
'spinner' becomes 'top' (a spinning top).
'big'+'top'='BIG TOP'
'home of' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for big top that I've seen before include "performance in The Ring" , "needed by Mae West, for one?" , "entertainment centre" , "'Main circus tent (3,3)'" , "Circus venue" .)
