Pea holder (3)
I believe the answer is:
pod
'pea holder' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for pod that I've seen before include "Seed carrier (eg, pea)" , "Group of whales" , "Fruit of a legume" , "The Borrowers father; seed case" , "Seed vessel" .)
