One comic misprint relates to the fiscal space (8)
I believe the answer is:
economic
'relates to the fiscal space' is the definition.
I can't judge whether this definition defines the answer.
'one comic misprint' is the wordplay.
'misprint' indicates anagramming the letters.
'one'+'comic'='onecomic'
'onecomic' is an anagram of 'ECONOMIC'.
Can you help me to learn more?
(Other definitions for economic that I've seen before include "Justified in terms of profitability" , "concerned with business" , "Relating ot the management of wealth" , "Relating to careful financial management" , "Coo, mince! (anag.)" .)
