Muuttuvien

Muuttuvien is the genitive plural form of the Finnish adjective muuttuva, which means changing or variable. In Finnish, adjectives decline to agree with the nouns they modify, so when the modified noun is plural and in the genitive case, the adjective takes the form muuttuvien. This form is used to express phrases such as “of the changing …” or “the changing …” within a larger noun phrase.

Common uses of muuttuvien appear in formal or technical language. Examples include muuttuvien olojen mukaan (“according to changing conditions”) and muuttuvien ilmiöiden tutkimuksessa (“in the study of changing phenomena”). The form signals that the described qualities or conditions are not fixed but subject to change, and it typically accompanies nouns in genitive plural.

Muuttuvien is not a standalone noun. It is a grammatical form of the adjective muuttuva and functions inside noun phrases to describe another noun in the genitive case. It should not be confused with muuttuja, the noun meaning “variable” in mathematics or programming, whose own genitive plural is muuttujien. The two forms come from different word classes and serve different grammatical roles in sentences.

In summary, muuttuvien is the genitive plural inflection of the Finnish adjective muuttuva. It appears in noun phrases to denote “the changing” or “the variable [in a changing sense],” and it is a common feature of Finnish adjective inflection in technical and academic writing.
