Paritusuch

Paritusuch is a fictional term used in speculative linguistics and worldbuilding to describe a recurring pattern of contact-induced language change. In this usage, paritusuch refers to a process in which a feature—such as a suffix, particle, or phoneme—spreads across multiple languages in a language family after prolonged contact, producing parallel forms that resemble a single shared origin.

Etymology: The coinage combines a Latin-like root paritus meaning appeared or arisen with a Germanic-sounding suffix -uch, chosen for its phonotactic plausibility in constructed languages. The term is not part of established linguistic theory outside fiction and worldbuilding contexts.

Theoretical scope: In the fiction and worldbuilding literature, paritusuch is described as a diffusion mechanism distinct from direct borrowing or calques. It emphasizes convergent development rather than copying, producing similar morphological endings in unrelated languages through social networks, bilingual communities, and shared narratives.

Usage and examples: In-world texts often illustrate paritusuch with a hypothetical trio of languages—Aure, Brin, and Kes—where an adjectival suffix -uch appears in all three after centuries of contact, yielding nominalizations and adjectives with overlapping semantics. The pattern is presented as a plausible though exclusively narrative mechanism to explain similarities without implying direct lineage.

History and reception: The concept emerged in online worldbuilding communities in the 2010s and has since appeared in speculative linguistics forums and fan wikis. Critics note that, as a fictional construct, paritusuch has no empirical evidence outside its narrative contexts.
