Sähköisissä

Sähköisissä is a Finnish inflected form of the adjective sähköinen, meaning electronic. It is used when the adjective modifies a plural noun in the inessive case, and it roughly conveys “in electronic …” or “in electronic devices/systems,” depending on the noun it accompanies. In everyday Finnish you will encounter phrases such as sähköisissä laitteissa (in electronic devices) or sähköisissä järjestelmissä (in electronic systems).

Grammatically, sähköinen is an adjective formed from the root sähkö- (electricity) plus the ending -inen. When the adjective is placed before a plural noun in the inessive case, it takes the form sähköisissä. This reflects Finnish’s system of agreeing adjectives with the noun in number and case. The result is a grammatically standard part of noun phrases describing electronic or digital contexts.

Usage notes: Sähköisissä does not function as an independent noun. It is a descriptive modifier used in sentences describing where something resides or exists, typically in technical, scientific, or descriptive prose. Because it is an inflected form, its exact meaning depends on the noun it modifies.
