Return Cadillacs if embroiled in this, referring to revenue, perhaps (6)
I believe the answer is:
fiscal
'referring to revenue perhaps' is the definition.
I can't judge whether this defines the answer.
'return cadillacs if embroiled in' is the wordplay.
'return' says the letters should be written backwards.
'in' says the answer is hidden in the clue.
'lacsif' can be found hidden inside 'cadillacs if embroiled'.
'lacsif' reversed gives 'FISCAL'.
'this' acts as a link.
Can you help me to learn more?
(Other definitions for fiscal that I've seen before include "Financial; to do with taxes" , "regarding tax" , "Such a drag" , "Relating to tax" , "Califs (anag.)" .)
