A nut is defined as a seed inside a hard shell.  The stuff surrounding the seed is called fruit.  The fruit is usually edible.  Some nuts defy the definition.  The Bush Nut is a tuber.  The Peanut is a legume. 
How many kinds of nuts are there?   It's hard to say because there are different categories of nuts and sometimes something called a nut is not a nut.  To further confuse things, some people are nuts.
 
Yes, some people are NUTS !
