fictionis

fictionis is the genitive singular of the Latin noun fictio, meaning "fiction," "a feigning," or "invention." As a Latin term, fictio denotes the act or result of fabricating something that is not real, and fictionis marks possession or relation, roughly translating as "of fiction." In classical and medieval Latin texts, fictionis appears in phrases discussing things that are imagined, pretended, or constructed.

In modern scholarship, fictionis is typically encountered only within quotes of Latin phrases or in studies of Latin grammar and vocabulary. It is not an English lexical item with a stand-alone sense; rather, it is treated as the Latin form of fiction used in scholarly contexts. When Latin phrases are translated, fictionis is commonly rendered as "of fiction" or "fiction’s" in English.

In philosophical and literary discussions, fictio is the common term for the broader concept of fiction. The related term fictio iuris or fictio legis appears in legal and rhetorical contexts to describe legal or rhetorical fictions; however, in those phrases the word most often appears in its nominative or adjectival form, not as fictionis in English-language usage.

There is no widely recognized organization, theory, or work formally known as "fictionis" as a standalone concept. It is primarily of interest as a linguistic form within Latin, relevant to scholars studying lexical history, philology, or the transmission of Latin terms into modern languages.
