kiihdytettyihin

Kiihdytettyihin is a Finnish inflected form used in technical and formal language. It represents the illative plural form of kiihdytetty, a past passive participle derived from kiihdyttää, meaning to accelerate. As a participial adjective, kiihdytettyyn or kiihdytettyihin describes objects or subjects that have undergone acceleration, and it is typically attached to plural nouns in illative case to indicate movement into or toward those accelerated items or states.

Morphology and use are characteristic of Finnish grammar, where participles can function as adjectives and take case endings; kiihdytettyihin combines the stem kiihdytetty with the illative plural ending -ihin. This form is most common in technical writing, such as physics, engineering, or materials science, where researchers discuss forces, processes, or materials that have been subjected to acceleration or acceleration-related treatment.

Examples of usage in neutral contexts include: "Kokeessa tarkasteltiin kiihdytettyihin osiin kohdistuvia voimia," meaning forces directed at the accelerated parts; and "kiihdytettyihin aineisiin liittyvät ominaisuudet kartoitettiin" referring to properties related to the accelerated substances. The exact interpretation depends on the noun it modifies, since kiihdytettyihin itself does not convey a complete idea without its accompanying illative plural noun.

Related forms include kiihdytetty (singular), kiihdytettyjen (genitive plural), and kiihdytettyihin (illative plural). The term is not commonly used outside technical or specialized discourse.
