A braid (also referred to as a plait) is a complex structure or pattern formed by interlacing two or more strands of flexible material such as textile yarns, wire, or hair. The simplest and most common version is a flat, solid, three-stranded structure. More complex patterns can be constructed from an arbitrary number of strands to create a wider range of structures (such as a fishtail braid, a five-stranded braid, rope braid, a

Although many cultures want to take sole credit for the braid, they cannot be traced to a single origin. Like how different versions of Cinderella are traceable to nearly every culture, braids, too, are polygenetic. One early example of hair braiding takes place in 1279-1213 bce as recorded in the story of Isis: "when some of the queen's maidens came to the well, she greeted them kindly and began to braid their hair."

. Braiding is traditionally a social art. Because of the time it takes to braid hair, people have often taken time to socialize while braiding and having their hair braided. It begins with the elders making simple knots and braids for younger children. Older children watch and learn from them, start practicing on younger children, and eventually learn the traditional designs. This carries on a tradition of bonding between elders and the new generation. Types of braids include

leather has been a widely practiced tradition in rural Australia since pioneering times. It is used in the production of fine leather belts, hatbands, bridles, dog leads, bullwhips, stockwhips, etc. Other leathers are used for the plaiting of heavier products suitable for everyday use. For nomadic peoples, braiding was a practical means of producing useful and decorative textiles. In other areas, such as the Pacific islands (where leaves and grasses are braided), and for many hill tribes, braids are made using minimal equipment. It was only when braiding became a popular occupation in the home or school, as it is in China and Japan, and when the Industrial Revolution came about, that specific tools were developed to increase production and make it easier to produce more complicated patterns of braids. Braids are also very good for making rope and decorative objects. Complex braids have been used to create hanging fibre artworks.

's negative terminal to the metal chassis. Similar braiding is used on pressurized hoses, such as in plumbing and hydraulic brake systems in automobiles. Braiding is also used for fibres for composite reinforcements. A property of the basic braid is that removing one strand unlinks the other two, as they are not twisted around each other. Mathematically, a braid with that property is called a Brunnian braid.


Metaphors

Braids are often used figuratively to represent interweaving or combination, such as in, "He braided many different ideas into a new whole." In some river and stream systems, small streams join and redivide in many places. Such stream systems are said to be braided. These are often found in
