Chowder morsel (4)
I believe the answer is:
clam
'chowder morsel' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for clam that I've seen before include "Edible shellfish" , "Aquatic creature" , "What could grip" , "ringing noise produced by > very reticent type" , "A silent type" .)
