A peanut is neither a pea or a nut

It sounds strange but it’s true; a peanut is no pea and its also no nut. A peanut is a legume.
The peanut, or groundnut (Arachis hypogaea), is a species in the legume or “bean” family.
After pollination, the fruit develops into a legume 3 to 7 cm (1.2 to 2.8 in) long, containing 1 to 4 seeds, which forces its way underground to mature. Hypogaea means “under the earth.”
