Eater's vice unfortunately producing gut (10)
I believe the answer is:
eviscerate
'gut' is the definition.
(thesaurus)
'eater's vice unfortunately' is the wordplay.
'unfortunately' is an anagram indicator (a bad or unfortunate spelling).
'eaters'+'vice'='eatersvice'
'eatersvice' is an anagram of 'EVISCERATE'.
'producing' acts as a link.
(Other definitions for eviscerate that I've seen before include "Draw" , "Disembowel" , "Remove essential parts" .)
