sähköisiin

Sähköisiin is a Finnish inflected form of the adjective sähköinen, meaning electric or electronic. It is the illative plural form, used with a plural noun to indicate movement toward, or relation to, electrical or electronic things in a sentence.

Morphology and usage

In Finnish, adjectives agree with the nouns they modify in number and case. When the noun is plural and in the illative case (often translated as “to” or “into” a direction toward), the adjective takes the ending -isiin. Thus, sähköinen becomes sähköiset in the nominative plural, and sähköisiin in the illative plural. The form is most commonly found with nouns referring to electrical or electronic objects, contexts, or domains, for example: sähköisiin laitteisiin (to electronic devices) or keskittyä sähköisiin toimitusjärjestelmiin (focus on electronic systems).

Grammatical notes

Sähköisiin does not have a separate lexical meaning beyond the adjective sähköinen itself; its precise sense depends on the accompanying noun. It appears in formal, technical, or descriptive Finnish to specify electronic or electrical aspects, hardware, technology, or systems. Other related inflected forms of sähköinen include sähköinen (base form, singular), sähköiset (nominative plural), ja sähköistä (partitive singular), käyttäessä muun muassa erilaisia taivutuksia eri lauseyhteyksissä.

Etymology

The word derives from sähkö- (electric, electric-powered) with the common Finnish adjective suffix -inen, forming sähköinen meaning electric or electronic. The illative plural form sähköisiin reflects standard Finnish grammar for adjectives modifying plural nouns in the illative case.
