Answer 2

It allows you to extend jQuery with your own functions.

For example,

$.fn.something = function{}

will allow you to use

$("#element").something()

$.fn is also synonymous with jQuery.fn which might make your Google searches easier.

This has been covered in some detail here:

Why jQuery do this: jQuery.fn.init.prototype = jQuery.fn?

But the short of it is that $.fn is an alias for $jQuery.prototype
