A model, an example that is representative.
A paradigm is a model or pattern that represents a typical example of the item or idea. In science, a paradigm is an agreement among scientists that details the scope, problems, and assumptions of a particular discipline. For example, there may be a paradigm for how to treat a particular type of cancer; what drugs to use and in what combinations and for how long, what outcomes may be expected. Our method for the classification of living things ( taxonomy) is a paradigm.
