Capital with top lucrative scheme (5-7)
I believe the answer is:
money-spinner
'lucrative scheme' is the definition.
The definition and answer can be both related to thinking as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'capital with top' is the wordplay.
I cannot really understand how this works, but
'capital' could be 'money' (I've seen this in another clue) and 'money' is located in the answer.
'top' could be 'spinner' ('spinner' can refer to a spinning top) and 'spinner' is present in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for money-spinner that I've seen before include "Highly profitable enterprise" , "Lucrative activity" , "Lucrative thing" , "Nice little earner?" , "Profitable thing" .)
