Fictivus

Fictivus is a term used in scholarly writing to denote a fictional or imagined construct introduced for analysis, argument, or storytelling. The term is not tied to a single discipline, and its precise meaning varies by context, but it commonly refers to entities or scenarios that do not exist in reality and are used as placeholders, thought experiments, or devices for explanation.

Etymology and usage notes: Fictivus derives from a Latin-inspired form meaning feigned or imagined, related to fictus “feigned” and fingere “to shape or fabricate.” In modern usage, fictivus appears as a label for hypothetical or invented constructs across disciplines, signaling that a referenced object or scenario is not empirical.

In philosophy and logic, fictivus describes hypothetical objects posited for the sake of argument or analysis, such as a fictitious observer, a fictional scalar, or other imagined elements that test reasoning without asserting their real-world existence.

In literary studies, fictivus designates invented elements of a narrative world, including characters, settings, or events, treated as integral to the work’s structure rather than as real-world equivalents.

In cognitive science and related fields, fictivus may be used to refer to mental representations that are imagined or recalled rather than derived from direct perception, aiding discussions of imagination and belief.

Overall, fictivus functions as a stylistic and analytical label to distinguish imaginary constructs from observed reality, supporting clarity in argumentation, analysis, and interpretation. See also: fiction, hypothetical, thought experiment, imaginary.
