Bear with appetite (7)
I believe the answer is:
stomach
I believe this clue is a double definition.
'bear with' is the first definition.
(thesaurus)
'appetite' is the second definition.
(stomach is a kind of appetite)
(Other definitions for stomach that I've seen before include "Corporation" , "Mac hosts his organ" , "Appetite for food" , "Abdomen" , "Inside" .)
