Stomach accommodates large excess (4)
I believe the answer is:
Here is my best explanation:
'excess' is the definition.
(I've seen this before)
'stomach accommodates large' is the subsidiary indication.
'stomach' becomes 'gut' (I've seen this in other clues).
'accommodates' indicates putting letters inside.
'large' becomes 'l'.
'gut' going around 'l' is 'glut'.
(Other definitions for glut that I've seen before include "Flood", "Excessively abundant supply", "Too much", "Surplus", "Abundant supply", "An excessive supply, maybe on the market", "A surplus or excess", "A surfeit as of crops", "An over-supply, harvest surplus" and "Fill to excess".)
