Stomach accommodates large excess (4)
I believe the answer is:
glut
'excess' is the definition.
(thesaurus)
'stomach accommodates large' is the wordplay.
'stomach' becomes 'gut' (I've seen this before).
'accommodates' indicates putting letters inside.
'large' becomes 'l'.
'gut' going around 'l' is 'GLUT'.
(Other definitions for glut that I've seen before include "Oversupply, plethora" , "An excessive supply or surfeit" , "Superfluity" , "Excess, surfeit" , "An over-supply, harvest surplus" .)
