Eg, pea or bean (6)
I believe the answer is:
legume
I believe this is a double definition.
'eg pea' is the first definition.
(I know that pea is a type of legume)
'bean' is the second definition.
(I've seen this before)
(Other definitions for legume that I've seen before include "A fruit that bears its seed in pods" , "A vegetable for e.g. mule" , "Veg as pea, bean" , "Bean, pea etc" , "mangetout for instance" .)
