naotype

Naotype is a term that has appeared in a limited number of specialized discussions to denote a representative or archetypal form within a system of classification. The term is not widely standardized and has no single agreed-upon definition across disciplines. In practice, naotype is used as a placeholder or baseline example—a prototypical type against which other types are compared or contrasted. Its exact meaning can vary by context, described as an original or ancestral form in hypothetical evolutionary models, or as a canonical sample in linguistic, typological, or data-driven analyses. Because of its informal status, authors may define naotype explicitly within a study, detailing what features constitute the naotype in that work.

The lack of a formal definition means that the concept is often explained locally rather than globally, and it should be interpreted in light of the specific field and methodology of the source. In some discussions, naotype is intended to mitigate circular reasoning by providing a reference point for classification or reconstruction. It is not intended to denote a universally recognized category, but rather a contextual reference that helps illustrate distinctions among related types.
