vastuullisilla

Vastuullisilla is a Finnish grammatical form: the adessive plural of the adjective vastuullinen, meaning "responsible" or "having responsibility." It refers to people or entities that bear responsibility in a given context and is used with plural nouns in the adessive case, for example vastuullisilla viranomaisilla (the responsible authorities) or vastuullisilla toimijoilla (the responsible actors).

Formation and forms: The adjective vastuullinen is built from the noun vastuu (responsibility) plus the suffix -llinen. In Finnish, adjectives agree with the nouns they modify in number and case. Related plural forms include vastuulliset (nominative plural), vastuullisille (allative plural), vastuullisten (genitive plural), and vastuullisia (partitive plural). Vastuullisilla specifically marks a plural noun in the adessive case.

Usage: Vastuullisilla appears chiefly in formal, administrative, or organizational language. It designates those who hold accountability in a given situation and can be used to contrast with others who do not bear responsibility. It is less common in casual speech and tends to appear with concrete agents such as authorities, organizations, or groups with defined duties.

Examples: Example sentences include: "Projektin valvonta on vastuullisilla viranomaisilla." and "Vastuullisilla toimijoilla on selkeät vastuut." These illustrate the sense of location or agency common to the adessive plural form.
