What does pea mean?
A pea is the small, round seed of a leguminous plant, especially the garden pea, which is eaten fresh as a green vegetable, dried as a pulse, or used in soups and stews. The related plant is an annual climber with flowers and pods containing several seeds; “sweet pea” also names a familiar ornamental flower. In ordinary British and American usage, pea usually refers to the edible seed rather than the whole plant, and the plural is peas. The word can also function as an informal verb in Australian and New Zealand English, meaning to complain or grumble, usually in phrases such as “what are you peaing about?” Less commonly, pea denotes a small pellet or projectile. Across these uses, pea is an ordinary, familiar word with a particularly concrete agricultural meaning and a geographically marked slang meaning.
The small, round seed of the pea plant (Pisum sativum), eaten fresh or dried; also the plant itself and, rarely, a small pellet or projectile.
"He planted a row of peas along the edge of the garden."
The seed is the dominant modern meaning. “Pea plant” is usually used when the whole plant is intended.
To complain or grumble.
"What are they peaing about now?"
Informal slang, chiefly Australian and New Zealand.
The standard plural is peas. The older form pease survives mainly in established expressions such as pease pudding.
"She added a cup of frozen peas to the stew."
Botanically, a green pea is a seed rather than a vegetable—a small distinction that makes the everyday word more interesting than it sounds.

Where does pea come from?
The modern English form belongs to a series of Middle English and Old English forms, including pe and pise, with pease surviving in a few traditional expressions. These forms came through Latin pisum, the name of the pea and pea plant, from Greek pison, whose ultimate source is uncertain. Pisum was also adopted as a scientific genus, and derivatives such as pisiform mean “pea-shaped.”
