Infiniitiv

Infiniitiv is a fictional or theoretical non-finite verbal form discussed in linguistic theory and used in some constructed languages. The term blends ideas of infinity and the infinitive, and it is not meant to replace standard infinitives in natural languages. In this framework, Infiniitiv functions as a non-finite predicate that can serve as the core of a clause or as a nominal-like element within larger phrases, without imposing a specific subject, tense, or aspect.

Morphology and syntax are typically designed so Infiniitiv lacks subject agreement and finite tense marking. It may carry markers for modality, definiteness, or evidentiality depending on the language system. Infiniitiv can appear embedded under finite verbs to yield general or potential readings, or it can operate adverbially to generalize an action without tying it to a particular event.

Semantics and use center on generalization and abstraction. The form is intended to express actions in a broad, abstract sense, such as habitualities, universal statements, or potentialities, rather than describing a specific occurrence. This makes Infiniitiv useful for cross-linguistic comparison of non-finite systems and for exploring how languages encode generalized action without a fixed subject.
