Reluctant to spend son's money (5)
I believe the answer is:
means
'money' is the definition.
(I've seen this in another clue)
'reluctant to spend son's' is the wordplay.
I cannot quite understand how this works, but
'son's' could be 's' and 's' is found within the answer.
The remaining letters 'mean' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for means that I've seen before include "Wherewithal" , "Imports" , "unpopular test" , "Intends; wealth" , "Pecuniary resources" .)
