Vaikutteisia

Vaikutteisia is the plural partitive form of the Finnish adjective vaikutteinen, which means influential or having influence. The form is used to describe nouns in the partitive case, typically indicating an indefinite amount or an object of a negation or ongoing action. In practice, vaikutteisia describes things, ideas, or phenomena that exert influence or have an influential character.

Etymology and morphology: The adjective vaikuteinen is derived from the noun vaikutus (influence, effect) with the suffix -teinen to form an adjective meaning related to influence. Its plural partitive ending is -sia, producing vaikutteisia when the noun it modifies is plural and in partitive. This form contrasts with the nominative plural vaikutteiset, which would modify nouns in the nominative plural.

Usage: Vaikutteisia is commonly used for ideas, proposals, studies, campaigns, or other items that exert influence. It is generally more suitable for inanimate or abstract items; for referring to influential people, Finnish often uses different expressions such as vaikuttava or vaikutusvaltainen, or phrases like vaikutusvaltaiset henkilöt.

Examples:

- Keskusteluun nousi useita vaikutteisia ehdotuksia. (The discussion brought up several influential proposals.)

- Tutkimus herätti vaikutteisia ajatuksia. (The study sparked influential thoughts.)

In summary, vaikutteisia is a grammatical form used to describe multiple influential items in Finnish, reflecting the language’s rich system of adjective inflection and case.
