Raised money on the radio (4)
I believe the answer is:
bred
'raised' is the definition.
(eg bred children)
'money on the radio' is the wordplay.
'money' becomes 'bread' (bread is slang for money).
'on the radio' shows a homophone (sound like).
'bread' is a homophone of 'BRED'.
(Other definitions for bred that I've seen before include "Produced offspring" , "Gave rise to" , "Nurtured" , "Brought up (to behave in particular way)" , "Developed (animal variety)" .)
