n.
Dry, hard, one-seeded fruit consisting of a kernel, usually oily, surrounded by a hard or brittle shell that does not split open at maturity.
Nuts include chestnuts , filberts , and walnuts ; but other so-called nuts are botanically seeds ( Brazil nut , pistachio ), legumes ( peanut ), or drupes ( almond and coconut ). Most edible nuts are well known as dessert nuts. Some nuts are sources of oil or fat. Not all nuts are edible; some are used for ornament.
