Other forms: peanuts
A peanut is the small crunchy thing that a famous sticky butter is made from. Salted peanuts, peanut butter, allergic to peanuts.
It is not a nut at all but a legume, closer to a pea than to an almond, and it grows underground after the flower bends down and buries itself. Peanut allergy is among the most serious food allergies and among the best studied. Peanuts as a plural means a trivial amount of money.

Also accepted in games: nut
Pea plus nut, which is exactly what it looks like and half right — a peanut is a legume rather than a nut.
From pea + nut, perhaps a folk etymology of pinda, pinder (still found in Southern US dialects).
