pyörivien

Pyörivien is a Finnish grammatical form that arises from the adjective pyörivä, meaning rotating or revolving. It is the genitive plural form of pyörivä and is used to modify nouns that are themselves in a genitive construction or are part of a larger genitive phrase. In Finnish, adjectives agree with the nouns they modify in number and case, so pyörivä changes to pyörivien when describing multiple rotating objects in the genitive plural.

This form typically appears in technical, scientific, or descriptive contexts where rotation is a defining characteristic of the described objects. For example, pyörivien koneiden aiheuttama melu translates to “the noise caused by the rotating machines,” and pyörivien kappaleiden lämpötila means “the temperature of the rotating parts.” Other common head nouns include laite (device), levy (disc), akseli (axis), kiekk o(e.g., wheel or disc), järjestelmä (system), and kappale (part), among others.

Grammatically, pyörivien is not a standalone noun; it functions as an attributive modifier that agrees with a plural head noun in the genitive case. The underlying meaning is derived from the combination of the adjective pyörivä and the noun it modifies, indicating that the referenced objects are characterized by rotation or spinning.

In summary, pyörivien is a productive and specialized inflection used to describe multiple rotating items within genitive constructions in Finnish, commonly encountered in engineering, physics, and technical writing.
