In favour of what creates wealth from tune
I believe the answer is:
for
'in favour' is the definition.
(I've seen this before)
'of what creates wealth from tune' is the wordplay.
I cannot quite understand how this works, but
'of' could be 'o' and 'o' is found within the answer.
'from' could be 'fr' (abbreviation) and 'fr' is found within the remaining letters.
No letters remain.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for for that I've seen before include "See 24" , "On behalf of" , "Favouring" , "In support of" , "Pro" .)
