Financial company cutting income badly (8)
I believe the answer is:
economic
'financial' is the definition.
(thesaurus)
'company cutting income badly' is the wordplay.
'company' becomes 'co' (abbreviation).
'cutting' is an insertion indicator (some letters cut their way into a word).
'badly' indicates anagramming the letters.
'income' is an anagram of 'enomic'.
'co' placed within 'enomic' is 'ECONOMIC'.
(Other definitions for economic that I've seen before include "Yielding a profit" , "Justified in terms of profitability" , "Productive: financially sound" , "Relating ot the management of wealth" , "viable" .)
