What is the term for an ideal example of a type or a prototype?

The term "archetype" refers to a quintessential example or a prototype of a particular type or concept. It embodies the most typical characteristics of its category, serving as a reference point for understanding other instances that share similar traits. Archetypes are often used in various fields such as literature, psychology, and design to describe ideal representations that evoke certain associations or functions.

In contrast, while "model," "standard," and "blueprint" represent concepts related to examples or templates, they do not encapsulate the idea of an ideal or original form as strongly as archetype does. A model can refer to a representation or simulation of an object, a standard indicates a recognized level of quality or attainment, and a blueprint typically refers to a detailed plan or design used in engineering and architecture. These alternatives are valid in their contexts but lack the specific connotation of an original or an exemplary type, which is what makes "archetype" the most precise term in this instance.
