Pea \Pea\, n.; pl. Peas (p[=e]z) or Pease (p[=e]z). [OE.
pese, fr. AS. pisa, or OF. peis, F. pois; both fr. L. pisum;
cf. Gr. pi`sos, pi`son. The final s was misunderstood in
English as a plural ending. Cf. Pease.]
1. (Bot.) A plant, and its fruit, of the genus Pisum, of
many varieties, much cultivated for food. It has a
papilionaceous flower, and the pericarp is a legume,
popularly called a pod.
[1913 Webster]
Note: When a definite number, more than one, is spoken of,
the plural form peas is used; as, the pod contained
nine peas; but, in a collective sense, the form pease
is preferred; as, a bushel of pease; they had pease at
dinner. This distinction is not always preserved, the
form peas being used in both senses.
[1913 Webster]
2. A name given, especially in the Southern States, to the
seed of several leguminous plants (species of Dolichos,
Cicer, Abrus, etc.) esp. those having a scar (hilum)
of a different color from the rest of the seed.
[1913 Webster]
Note: The name pea is given to many leguminous plants more or
less closely related to the common pea. See the
