What word represents a perfect example of a class or type?

The term "Epitome" is often used to signify a perfect example or representation of a particular class or type. It embodies the essence of the characteristics, qualities, or attributes that define the category it represents. When something is described as the epitome of a given concept, it implies that it embodies those traits in their most concentrated and ideal form. In literature and conversation, the word is used to convey that something not only exemplifies the essential features of a type but does so in an exemplary manner that can be seen as the highest standard.

The other terms, while related, convey slightly different meanings that do not align as closely with the idea of a perfect example. For instance, "Model" typically refers to a representation used for demonstration or simulation but does not necessarily imply perfection. "Prototype" refers specifically to the first or preliminary version of something from which other forms are developed, highlighting a developmental phase rather than a consummate example. "Standard" generally denotes an accepted or widely recognized level of quality or attainment but does not capture the notion of being a perfect representation in the way that "epitome" does.
