kiinnostavien

Kiinnostavien is a Finnish adjective form meaning “of interesting [things/subjects],” and it is the genitive plural form of kiinnostava, which means “interesting.” It is used to modify a noun that is in the genitive case, forming a compound noun phrase or showing a relationship to the genitive noun.

In practice, kiinnostavien appears in phrases such as kiinnostavien asioiden lista (a list of interesting things) or kiinnostavien aiheiden tutkimus (the study of interesting topics). The form cannot stand alone as a noun; its use depends on the grammatical case of the noun it modifies. For non-genitive contexts, other forms of the adjective are used, for example kiinnostavat (nominative plural) or kiinnostavia (partitive plural), depending on the sentence.

Etymologically, kiinnostava is derived from the verb kiinnostaa, “to interest,” with the -va/-vä adjective suffix. The genitive plural ending -ien marks possession or a relational link to a plural noun in the genitive, as in kiinnostavien asioiden.
