Repeatedly has one of your five-a-day (3)
I believe the answer is:
pea
'one of your five-a-day' is the definition.
I can't tell whether this defines the answer.
'repeatedly has' is the wordplay.
'has' indicates a hidden word.
'PEA' is hidden within 'repeatedly'.
Can you help me to learn more?
(Other definitions for pea that I've seen before include "Edible green seed" , "veg" , "Leguminous plant" , "Seed eaten as vegetable" , "Pulse vegetable" .)
