hyödyllisten

Hyödyllisten is a Finnish grammatical form of the adjective hyödynllinen (more commonly spelled hyödyllinen), meaning useful or beneficial. It is the genitive plural form and is used to modify nouns in the genitive plural, typically in phrases that express “of useful [things]” or describe a group of items or concepts as being useful.

Morphology and usage: Finnish adjectives decline to agree with the noun they describe. The nominative plural form of hyödyllinen is hyödylliset, while the genitive plural form is hyödyllisten. Other related forms include singular genitive hyödyllisen and partitive plural hyödyllisiä. Hyödyllisten appears in phrases where the head noun is in the genitive plural, for example hyödyllisten asioiden lista, meaning a list of useful things, or hyödyllisten tuotteiden valmistustapa, meaning the production method of useful products. In these constructions, hyödyllisten modifies the genitive noun (asioiden, tuotteiden, etc.) rather than standing alone.

Examples and notes: The form is common in descriptive or instructional Finnish, dictionaries, and written prose that discusses categories or sets of items considered useful. It is not used as an independent noun without a head noun in the genitive; rather, it functions as part of a larger noun phrase. Because Finnish grammar relies on case and number agreement, correct usage depends on the relationship between the adjectives and the nouns they describe.
