Supinparticipform

Supinparticipform is a theoretical linguistic term for a hypothetical non-finite verb form that merges the purposive semantics of a supine with the adjectival or adverbial function of a participle. The concept is not widely attested in established grammars and is primarily encountered in theoretical discussions and some explorations of constructed languages. Etymology-wise, the name is a straightforward portmanteau of supine and participle form.

In theory, a supinparticipform would be non-finite and might appear in subordinate clauses to express purpose, direction, or a modifying relation between a verb and a following noun. Because this term is not standardized, its exact properties can vary across proposals: some describe a simple suffix attached to a verb stem, while others imagine a periphrastic construction that simultaneously conveys purposive meaning and modifies a nominal element.

Morphology and syntax are the main areas of variation in the literature. Proponents emphasize a single form that combines two functions—supine-like purpose and participle-like modification—without fully collapsing into either category. Critics point out the risk of blurring typological distinctions among non-finite verb forms and note the lack of empirical attestation in natural languages.

Examples of a supinparticipform are speculative and typically confined to discussions of hypothetical linguistics or designed languages. In such contexts, a verb stem may take a supposititious suffix or construction labeled as the supinparticipform to express “in order to …” while simultaneously modifying a following noun.
