Soggy mass (4)
I believe the answer is:
pulp
'soggy mass' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for pulp that I've seen before include "Mush" , "Soft structureless mass - type of fiction" , "Soft, soggy mass" , "Crush" , "Soft moist mass, may be crushed" .)
