Virtue having reserve of money for head of business's remarkable insight (10)
I believe the answer is:
profundity
'remarkable insight' is the definition.
The answer and definition can be both related to thinking as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'virtue having reserve of money for head of business's' is the wordplay.
I cannot quite understand how this works, but
'reserve' could be 'fund' (I have seen 'Reserve of money ' mean 'fund' so perhaps 'reserve' could also mean 'fund') and 'fund' is located in the answer.
'of' could be 'o' and 'o' is found in the answer.
'money' could be 'p' and 'p' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for profundity that I've seen is " depth of insight".)
