Toinfinitiivin

Toinfinitiivin is a hypothetical linguistic term used to describe a proposed method for forming the infinitive by merging the infinitival marker with the verb stem into a single form. It is not a standard feature in the grammars of widely spoken natural languages and is mainly discussed in theoretical linguistics and in discussions of constructed languages.

Conceptually, toinfinitiivin envisions the infinitive as a fused or semi-fused morpheme that combines a forward-looking marker (often likened to the English to) with the verb stem. This contrasts with systems that keep a separate infinitival particle (as in English) or with purely suffixal or bare infinitives found in other languages. The notion is used to explore how non-finite clauses might function if the boundary between particle and stem were reorganized or simplified.

Typological note: in a language implementing toinfinitiivin, infinitival forms could appear as a single word or as a tightly bound clitic sequence. Such a system would influence how non-finite clauses interact with tense, aspect, mood, and clausal control, and it can be modeled in theoretical syntax to compare with existing infinitive types.

Application and discussion: the concept serves as a thought experiment for morphophonology and the syntax-semantics interface, and it provides a framework for designers of constructed languages who want to experiment with compact non-finite forms. The idea remains speculative and illustrative rather than a description of a documented natural language.

Example (fictional): in a hypothetical language, the verb walk might be realized as twalk when expressed in the infinitive, used in non-finite clauses such as “I want twalk” to illustrate the fused form.
