Goodness, die cutter in need of repair (9)
I believe the answer is:
rectitude
'goodness' is the definition.
(thesaurus)
'die cutter in need of repair' is the wordplay.
'in need of repair' is an anagram indicator.
'die'+'cutter'='diecutter'
'diecutter' with letters rearranged gives 'RECTITUDE'.
(Other definitions for rectitude that I've seen before include "Strict propriety" , "Certitude about moral goodness" , "Correctness" , "Moral integrity" , "Uprightness, integrity" .)
