Nuts are a category of hard-shelled fruit, many of which are edible. The term "nut" in English includes a variety of dried seeds and fruits, although to biologists, only a certain number that satisfy a botanical definition can be regarded as true nuts.
A nut, in the botanical definition, is a dry fruit with one seed in which the ovary wall becomes hard at maturity. As such, many nuts in the culinary sense are not true nuts in the botanical definition, including almonds, pecans, walnuts, Brazil nuts, candlenuts, cashew nuts, horse-chestnut, Macadamia nut, peanut, pine nut and Pistachio nut.
