Considerable money, locally, for very important person (3,6)
I believe the answer is:
big cheese
'important person' is the definition.
(I've seen this in another clue)
'considerable money locally for' is the wordplay.
I cannot really see how this works, but
'considerable' could be 'big' and 'big' is found within the answer.
'money' could be 'c' and 'c' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
'very' acts as a link.
Can you help me to learn more?
(Other definitions for big cheese that I've seen before include "boss" , "Important chap" , "Important person (slang)" , "Notable" , "VIP" .)
