Guts put in container (6)
I believe the answer is:
bottle
I believe this clue is a triple definition!
'guts' is the first definition.
(thesaurus)
'put' is the second definition.
(bottling is a kind of putting)
'in' acts as a link.
'container' is the third definition.
(I know that bottle is a container)
(Other definitions for bottle that I've seen before include "Nerve (sl.)" , "Heart" , "(Drink) container" , "Nebuchadnezzar?" , "Narrow-necked vessel" .)
