elektrisiin

Elektrisiin is a Finnish inflected form of the adjective elektrinen, meaning electrical. It is used to modify plural nouns in the illative case, often conveying the sense of movement toward or into something electrical. For example, elektrisiin järjestelmiin means “into electrical systems,” and elektrisiin laitteisiin means “into electrical devices.” As with other Finnish adjectives, elektrisiin agrees with the noun it modifies in number and case.

In contemporary Finnish, elektrinen is a loanword in many technical contexts, while sähköinen is more common in everyday language. Elektrisiin tends to appear in scientific, engineering, and industrial terminology when describing plural objects in an illative construction. The form is part of general Finnish grammar, where adjectives take the same case endings as the nouns they describe.

Etymology traces elektrinen to the Swedish word elektrisk (electrical), which in turn derives from Latin electricus and Greek elektron, a root associated with amber and early electricity. The term elektrinen is used alongside sähköinen in various compound terms and field-specific phrases, reflecting a nuance where elektrinen often appears in more formal or technical language.
