eristävinä

Eristävinä is the Finnish essive plural form of the adjective eristävä, meaning insulating or isolating. The essive case expresses a temporary state or role, roughly translating to “as …” or “in the capacity of.” When used with a plural noun in the essive, eristävä becomes eristävinä to describe multiple items that function as insulating substances or measures.

Morphology and use

Eristävä stems from eristää, which means to insulate or to isolate. The essive plural form eristävinä is typically employed in technical, construction, or descriptive contexts where several items are described in the sense of “as insulating [materials/ways].” Common accompanying nouns in this construction include aineina (as substances) or toimenpiteinä (as measures).

Examples

- Rakenteessa käytettiin eristävinä aineina mineraalivillaa ja polystyreeniä. (In the construction, mineral wool and polystyrene were used as insulating substances.)

- Eristävinä toimenpiteinä mainittiin ilmanvaihdon parantaminen ja tiivistysten tehostaminen. (As insulating measures, improving ventilation and tightening were mentioned.)

Etymology

The form derives from the stem eristävä plus the essive plural suffix -inä, which marks a temporary state or role for multiple items.
