necunoscui

Necunoscui is a neologism used to describe the state or process of not knowing something that could be known. In discussions about knowledge gaps, data incompleteness, and uncertainty, the term is invoked to highlight the boundary between knowns and unknowns and to emphasize the presence of missing or inaccessible information.

The term combines a prefix meaning "not" with a root related to knowledge and understanding. It is modeled on Romance language patterns and elements of Romanian vocabulary, but it is not established in standard dictionaries or formal philosophy literature. Its exact etymology varies by author, and it is generally treated as a conceptual label rather than a fixed linguistic form.

In practice, necunoscui is used to refer to a deliberate or inadvertent lack of knowledge that affects decision-making, risk assessment, or model design. It is associated with information gaps, unobserved variables, and epistemic blind spots. Some writers use it to describe unknown unknowns in risk analysis or to distinguish between “unknowns we know we don’t know” and “unknowns we don’t know we don’t know.”

Status and reception: The term remains niche and informal; there is no widespread consensus on its definition or scope. Proponents view it as a concise label for a familiar problem, while critics argue that it adds ambiguity or overlaps with existing terms such as ignorance, uncertainty, or unknown unknowns.
