käsiin

Käsiin is a Finnish word that functionally serves as the illative plural form of the noun käsi, meaning hand. In Finnish grammar, the illative case indicates movement toward or into a location or object, and its plural form with käsi yields the sense of “into the hands” or “to the hands” of multiple people.

As a grammatical form, käsiin is most likely to appear in written Finnish, including literary or descriptive prose, when a speaker or writer wants to convey transfer, placement, or direction into several hands—whether in a literal, physical sense or in a metaphorical sense such as handing over responsibility or control. The construction relies on the broader set ofFinnish case and number inflection rules for the noun käsi, and its exact usage will align with standard illative plural patterns in the language.

Origin and related forms: käsi is a basic Finnish noun meaning hand, with a range of inflected forms across cases and numbers. Käsiin specifically marks the illative plural, contrasting with singular illative forms such as käteen. These forms are part of Finnish noun morphology, which uses vowel and consonant changes to indicate grammatical relationships rather than prepositions alone.
