Definition & Meaning of "prototype"

What is a "prototype"?

In semantics, a prototype is the best or most typical example of a certain category. It represents what people usually think of when they consider a particular concept. For instance, within the category "bird," a prototype would be a sparrow or a robin, as these examples most clearly show the common features shared by all birds. This helps people understand and organize different concepts based on their most familiar or representative examples.
