Sähköisestä

Sähköisestä is the elative singular form of the Finnish adjective sähköinen, meaning electric or electrical. The elative case expresses origin or source, so sähköisestä is used to describe something that comes from electricity or is related to electricity when the noun it modifies is in the elative form. In ordinary attributive use before a noun, the base form sähköinen is typically used to mean “electrical.”

Grammatical notes and usage context: sähköisestä is a inflected form that belongs to adjectives ending in -inen. It is not the usual attributive form for a simple “electrical” description; instead, it appears when the noun it modifies is in elative, indicating origin or source. For example, in the phrase sähköisestä signaalista the meaning is “from the electrical signal.” Similarly, sähköisestä järjestelmästä means “from the electrical system.” When you want to say “an electrical signal” or “an electrical system” as a characteristic rather than a source, you would use sähköinen ennen the noun (for example, sähköinen signaali, sähköinen järjestelmä).

Related forms and broader context: sähköinen as the base adjective covers typical descriptions of things related to electricity. The elative form sähköisestä is one of several inflected forms that Finnish adjectives can take to agree with the case and number of the noun they modify. Understanding sähköisestä helps in parsing technical or scientific Finnish where electricity is a central topic, and it illustrates how Finnish uses case endings to convey meaning beyond simple adjective-noun agreement.
