Material in gorge (5)
I believe the answer is:
stuff
I believe this is a double definition.
'material' is the first definition.
(I know that material can be written as stuff)
'gorge' is the second definition.
(I know that gorge can be written as stuff)
'in' acts as a link.
(Other definitions for stuff that I've seen before include "crowd" , "Material; fill full" , "12 [GLUT]" , "Jam" , "Substance; material" .)
