Destroy stomach (3)
I believe the answer is:
gut
I believe this clue is a double definition.
'destroy' is the first definition.
(thesaurus)
'stomach' is the second definition.
(I've seen this before)
(Other definitions for gut that I've seen before include "Remove innards from" , "Paunch" , "Stomach, belly" , "Tug in intestine" , "strong feelings" .)
