Pod item (3)
I believe the answer is:
pea
'pod item' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for pea that I've seen before include "Leguminous vegetable" , "Spherical vegetable" , "Vegetable in a whistle" , "Cause of a princess's insomnia?" , "It may climb frame" .)
