Sähköksi

Sähköksi is the translative singular form of the Finnish noun sähkö, meaning electricity. The translative case, marked by the suffix -ksi, indicates a change of state into something or a designation as that thing. Accordingly, sähköksi is used for expressions that describe a transition into electricity or a sense of becoming electricity, usually in technical or metaphorical contexts.

In everyday Finnish, sähköksi is relatively rare and often sounds technical. More common usage involves the adjective form sähköinen (electric) in the translative or other cases, for example sähköiseksi (to become electric) or other constructions that describe electric qualities. The noun form sähköksi typically appears in specialized texts about energy conversion, electrical engineering, or scientific descriptions, and in metaphorical language that treats electricity as a state or identity.

The word sähkö itself is the Finnish term for electricity and serves as a productive base for many compound words, such as sähköposti (email), sähköverkko (electrical grid), sähköaut (electric car), and sähkötekniikka (electrical engineering). These compounds illustrate how Finland’s technical vocabulary often builds on the core concept of electricity.

Etymologically, sähkö emerged as the basic term for the phenomenon in the modern Finnish lexicon, adopted during the rise of electrical science in the 19th century. As with many Finnish nouns, it forms various case endings and compounds to express different grammatical and semantic roles.
