supistuvista

Supistuvista is a Finnish grammatical form belonging to the present active participle of the verb supistua, meaning to contract or shrink. In Finnish, the form is used as an adjective within noun phrases and agrees with the number and case of the noun it modifies. The specific ending -ista signals the plural elative case, so supistuvista translates roughly to “from the contracting ones” or “of the contracting ones” in English.

Morphology and usage: The base participle supistuva combines the verb stem with the -va/-vä suffix to create the present active participle. When inflected for plurality and the elative case, the ending becomes -ista, yielding supistuvista. This form is typical in technical, medical, or scientific Finnish, where it points to a source or origin related to contracting things or processes. Because it is a participial inflection, supistuvista can appear in various syntactic positions, modifying multiple nouns in the same phrase.

Examples: Supistuvista verisuonista means “from the contracting blood vessels.” Supistuvista lihaksista means “from the contracting muscles.” In both examples, the phrase functions to indicate source or relation to contraction in a plural context.

Related forms: The related base forms include supistuva (present active participle in the singular or non-inflected form) and supistua (to contract). The elative plural ending -ista is part of a broader system of Finnish case endings used with adjectives and participles.
