A pattern is a form, template, or motif (or more abstractly, a set of rules ) which can be used to make or to generate things or parts of a thing. This is especially true if the things that are generated have enough in common for the underlying pattern to be suggested or understood, in which case the things are said to exhibit the pattern.
Pattern relies on the principles of rhythm and repetition.
Some patterns are named; simple decorative examples are stripes, herringbone, plaids and zigzags.
