Dealing with revenue approximately on island in Florida (6)
I believe the answer is:
fiscal
'dealing with revenue' is the definition.
I can't tell whether this defines the answer.
'approximately on island in florida' is the wordplay.
'approximately' becomes 'ca' (abbreviation for circa).
'on' says to put letters next to each other.
'island' becomes 'is' (geographical abbreviation).
'in' is an insertion indicator.
'florida' becomes 'fl' (abbreviation for Florida).
'ca' after 'is' is 'isca'.
'isca' inserted inside 'fl' is 'FISCAL'.
Can you help me to learn more?
(Other definitions for fiscal that I've seen before include "Relating to taxation" , "Financial; to do with taxes" , "Relating to tax" , "Relating to the public revenue" , "To do with public revenue of califs" .)
