Calf is crazy about money (6)
I believe the answer is:
fiscal
'calf is crazy about money' is the definition.
I can't judge whether this defines the answer.
'calf is crazy' is the wordplay.
'crazy' indicates an anagram.
'calf'+'is'='calfis'
'calfis' is an anagram of 'FISCAL'.
Can you help me to learn more?
(Other definitions for fiscal that I've seen before include "Relating to government revenue" , "Such a drag" , "Of public finances" , "To do with public revenue of califs" , "For monetary gain" .)
