A '''staple''' (from Old English stapol<ref>http://www.etymonline.com/index.php?term=staple&allowed_in_frame=0</ref>) is a fastener which is usually made of [[metal]].  It is used to attach multiple objects, or  bind one or more loose objects to a solid one.  Most modern staples are thin strips or wires which are punched into or through material.  However, other kinds exist, such as Dovetail Staples used in ancient construction.

Paper staples are the most common kind of staple used today. This kind of staple (and most others) is made of metal and consists of a crown (the top), a pair of legs (the sides), and teeth at the bottom, which are the ends of the legs.  These are loaded into a device which punctures the paper with the staple, and bends the legs either inward or outward.

Staples are also sometimes used to affix paper or paperboard to other surfaces.  They are often used on bulletin boards, drywall, and even telephone poles.  When used in this manner, staples are punched through the paper and into the holding surface, but the legs remain straight.

==Construction staples==

==Construction staples==

Ancient construction sometimes used dovetail staples to attach stone blocks to one another.  These were created by carving out a grove in stone, then pouring molten metal into it.  However, modern construction uses a much smaller variety, much like paper staples in form.  Modern staples are bent metal fasteners which are usually placed using a staple gun or staple hammer (a.k.a. hammer tacker).  They are often used to hold wires, so it is not uncommon for them to have an insulation coating or a plastic strip to help protect the wires.

If a person's (or sometimes animal's) skin gets cut so that it separates, it becomes very difficult for the injury to heal.  For this reason, the two sides are pressed against each one so that healing is expedited.  This is sometimes done with one of several special threads or strings, which is used to sew the sides together.  In other cases, especially after surgery, staples are sometimes used.

Other kinds of staples exist as well, such as those used in the past to repair pottery and china. Narrow staples are also sometimes used for creating wooden boxes.  Many varieties exist for both the purposes mentioned and those which have not been referenced.
