Calf is mad about money (6)
I believe the answer is:
fiscal
'calf is mad about money' is the definition.
I can't tell whether this defines the answer.
'calf is mad' is the wordplay.
'mad' indicates anagramming the letters.
'calf'+'is'='calfis'
'calfis' anagrammed gives 'FISCAL'.
Can you help me to learn more?
(Other definitions for fiscal that I've seen before include "Relating to government revenue" , "Relating to taxes" , "dealing with tax" , "Such a drag" , "Budgetary" .)
