vegetable

adj. consisting of or pertaining to vegetables

n. plant, edible fruit of a plant; (Informal) person having little or no brain activity (usually due to an injury)

Vegetable is a term which generally refers to an edible part of a plant. The definition is traditional rather than scientific and is somewhat arbitrary and subjective. All parts of herbaceous plants eaten as food by humans, whole or in part, are normally considered vegetables. Mushrooms, though belonging to the biological kingdom Fungi, are also commonly considered vegetables. In general, vegetables are thought of as being savory, and not sweet, although there are many exceptions.  Nuts, grains, herbs, spices and culinary fruits (see below) are normally not considered vegetables.
