Definiowan

Definiowan is a hypothetical term used in semantic theory and the study of definitional systems to denote a unit whose reference is fixed entirely by a formal definition within that system. The concept is employed in thought experiments about how dictionaries, ontologies, or formal languages assign meaning when definitions themselves rely on other defined terms, potentially creating circularity or fixed-point scenarios.

Origin and usage: The term is a coined neologism that appears mainly in theoretical discussions and illustrative examples. It is not an established term in mainstream linguistics or philosophy of language, but it serves as a convenient shorthand for examining how self-referential definitions operate within a closed definitional framework.

Definition and behavior: A definowan has no independent referent outside the framework that defines it. Its meaning is determined by rules that relate it to other definowan and primitive terms within the system. In formal models, definowans help analyze conditions under which a definitional network is coherent, or conversely, degenerates into circularity, inconsistency, or ambiguity, depending on the allowed types of definitions (circular, mutual, or recursive).

Applications and implications: The idea of a definowan is used to explore questions about definitional closure, the limits of dictionary-like meaning, and the behavior of self-describing ontologies. In artificial intelligence and computational linguistics, analogous constructs appear in self-referential prompts and self-describing knowledge bases, highlighting challenges in grounding, interpretability, and the management of circular definitions.
