occurrednot

Occurednot is a neologism proposed in linguistic and philosophical semantics to denote the non-occurrence of an event within a specific temporal or modal context. It is described as an operator that attaches to propositions about events to indicate that the described event did not take place, potentially under a hypothetical or counterfactual framework. The concept is distinguished from ordinary negation by its focus on event-level non-occurrence and its interaction with tense, aspect, and modality in theoretical analyses.

Origin and naming: The term occurrednot emerged in discussions of event structure and negation in the 2010s as a portmanteau of "occurred" and "not." It has appeared primarily in niche papers, lecture notes, and online glossaries that explore how language encodes the non-occurrence of events. There is no mainstream adoption or standardized notation, and usage varies across frameworks.

Semantics and usage: In formal analyses, occurrednot is treated as an operator that applies to a proposition about an event. If P is a statement like "The rainfall occurred," then occurrednot(P) represents "The rainfall did not occur." In some proposed notational schemes, occurrednot may be written as a dedicated operator or as a functional marker on an event predicate, depending on the theoretical framework. The concept is most often discussed in theoretical contexts rather than in everyday language.

Reception and status: Occurednot remains a fringe concept with limited empirical support and no consensus on its practical utility. Critics argue that it adds complexity to negation and event analysis without clear advantages, while proponents see potential for clarifying distinctions between event non-occurrence and broader negation. Its current use is primarily within specialized discussions of event structure, negation, and modality.
