Peanuts are actually not nuts
Unlike Cashew and even Walnuts, peanuts are not categorized under nuts.
In reality, they are Legumes. A legume is basically a dry fruit that is found within a pod or a shed, just like a pea or a bean. So, you see the connection? You must now be wondering, why the name Peanuts? Well, nobody really knows! Maybe people initially assumed that they were nuts until they realized the difference, and named them Peanuts because they resembled peas and tasted like nuts.
