A
braid (also referred to as a
plait) is a complex structure or pattern formed by interlacing three or more strands of flexible material such as textile yarns,
wire, or hair. Compared to the process of
weaving which usually involves two separate, perpendicular groups of strands (
warp and
weft), a braid is usually long and narrow, with each component strand functionally equivalent in zigzagging forward through the overlapping mass of the others.
