vastuuihin

Vastuuihin is a Finnish grammatical form, specifically the illative plural of the noun vastuu, meaning responsibility or obligation. The illative case expresses direction toward something or a figurative entering into a state, so vastuuihin can be interpreted as “into responsibilities” or “toward responsibilities.” The form is formed by adding the illative plural suffix -iin to the stem vastuu-.

In practice, vastuuihin appears mainly in formal or written Finnish, often within larger phrases that discuss duties or assignments in relation to multiple responsibilities. Common usages include phrases such as vastuihin liittyvät velvoitteet (obligations related to responsibilities) or vastuuihin kohdistuva paine (pressure directed toward responsibilities). The term emphasizes the relationship between entities—such as individuals, teams, or organizations—and the set of duties they bear.

Grammatically, vastuuihin is one of several case forms of vastuu, alongside forms like vastuun (genitive) and vastuulle (allative). There is no separate semantic domain for vastuuihin beyond the ordinary concept of responsibility; its role is primarily syntactic, signaling direction toward or involvement with multiple responsibilities within a sentence.

Usage considerations include that speakers often prefer simpler constructions in spoken Finnish, such as using vastuu or vastuut (plural) or phrases like liittyvät vastuut. Vastuuihin remains a legitimate, if somewhat formal, option for expressing nuanced relationships among duties in written discourse.
