A groundnut, also known as a peanut, is a legume (not a true nut) from the Fabaceae family, primarily grown for its edible, protein- and oil-rich seeds that grow underground in a pod. It is a popular food source, consumed roasted, boiled, or used to make peanut oil and butter, and is a valuable agricultural commodity and crop in many tropical and subtropical regions worldwide.
