Nominalisiin

Nominalisiin is a fictional linguistic term used in worldbuilding and speculative linguistics to describe a family of nominal-centric constructions found in imagined languages. The core idea is that referents are encoded primarily by nominal morphology and determiner-like markers, with verbs playing a subsidiary role. In nominalisiin systems, sentence meaning is often anchored by the nominal core, allowing a more flexible word order and a strong emphasis on referential identity and properties.

Etymology and scope: The term blends the word nominal with a fictional suffix -isiin, chosen to suggest inflectional variety across phrases. It is not attested in natural languages and remains a concept within constructed-language studies and fiction. The concept is used to explore how grammatical weight shifts when nouns carry most of the information about a proposition.

Linguistic features: Nominalisiin structures typically exhibit rich nominal morphology, including case markings, number agreement, and determiner or classifier systems. Verbs are frequently analytic, periphrastic, or reduced in inflection. Agreement tends to align with the nominal core, while adjectives and classifiers further modify the referent. Semantics center on referential identity and property ascription of the head noun, with modifiers providing additional specificity. Tense and aspect are often indicated by separate particles or by adverbial modifiers attached to the nominal phrase rather than through verb conjugation.

Applications and reception: The concept is widely used in conlangs, role-playing settings, and speculative linguistics to imagine how information structure changes when nominal phrases bear the primary grammatical burden. Critics view nominalisiin as a theoretical construct rather than an empirically documented typology, but it serves as a useful tool for exploring alternative grammatical architectures.
