Properus

Properus is a term that does not have a single, widely recognized definition in established disciplines. In published sources, it most often appears as a neologism or a proper noun rather than as a standard lexical item.

Etymology and meaning: The form resembles Latin-based neo-Latin coinages and is commonly associated with notions of propriety or suitability in speculative uses. It is not attested as a classical Latin word in major lexica. When employed by authors, properus is typically chosen to evoke themes of urgency, adequacy, or fittingness, depending on context, rather than to reference a fixed concept.

Usage: In fiction and world-building, properus may function as a character name, a place, an organization, or a theoretical notion introduced within a story. In academic or linguistic discussions, it may be used as a placeholder term to illustrate morphological processes or to discuss the idea of “the proper” in debates about propriety or appropriateness. There is no standard definition or canonical usage.
