A peanut, also known as a groundnut, is the fruit of Arachis hypogaea, a plant in the family Fabaceae. The peanut is classed as a grain legume rather than as a botanical nut, although in culinary and colloquial use it is generally treated as one. Uses of peanuts include consumption as a snack and in various dishes, peanut butter, and – due to its high oil content – as a vegetable oil. Peanuts cause allergic reactions in some humans. Clockwise from top left, this photograph shows a peanut with its shell cracked open, a whole unshelled peanut, an unpeeled peanut seed, a halved peeled seed, and a whole peeled seed. This picture was focus-stacked from 31 separate images.Photograph credit: Ivar Leidus
Wikipedia:Did you know... is a section you can see on the Main Page. Wikipedia:Did you know (WP:DYK) is the project page for the "Did you know" section.
The DYK section showcases new or expanded articles that are selected through an informal review process. It is not a general trivia section. For the discussion page see WT:DYK.
Beginners should consult this Did You Know glossary if they don't understand any of the terms used. Beginners may like to start by looking at a summary of our many rules: this provides links to pages with more detailed explanations (which in turn may link to even more detailed pages).
All this will not be finished in the first 100 days. Nor will it be finished in the first 1,000 days, nor in the life of this Administration, nor even perhaps in our lifetime on this planet. But let us begin.
