Vegetable repeats in the stomach (3)
I believe the answer is:
pea
'stomach' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'vegetable repeats in' is the wordplay.
'in' indicates the answer is hidden within the clue.
'PEA' is hidden in the letters of 'vegetable repeats'.
'the' acts as a link.
Can you help me to learn more?
(Other definitions for pea that I've seen before include "Small vegetable" , "Tiny stone" , "Edible seed from pod" , "The plant is a strange ape" , "Leguminous plant" .)
