efekteissä

Efekteissä is a Finnish inessiivinen monikkomuoto of the noun efekti, meaning the plural “in the effects” or “within the effects.” It is used when referring to multiple effects observed or present within a system, process, or context. The form appears mainly in technical, scientific, or formal Finnish texts, and in discussions about where or how effects occur.

Morphology and usage notes: Efekteissä is formed from the plural nominative efekti- plural (efektit) with the inessiivisen plural suffix -issä, yielding efek-teis-s? The standard form is efekti → efektit in the nominative, efekti- plural stem becomes efek-teissä in the inessive plural. In practice, this construction signals location or state “in the effects.” It is common in academic writing, pharmacology, physics, psychology, and film or stage contexts where multiple effects are analyzed or described.

Relation to related terms: The more everyday or broadly used synonym for “effect” in Finnish is vaikutus, with plurals kuten vaikutukset and inessive forms like vaikutuksissa. Efekteissä tends to be preferred in contexts that directly discuss effects as concrete phenomena or when the source language framing uses the loanword efekti. Other related terms include efekti tai effektitekijät for specific effects, and efektien analysointi for the analysis of effects.

See also: efekti, efektit, vaikutus, vaikutukset. Notes: Efekteissä is a niche grammatical form not typically used in casual speech; in many contexts, vaikutus or vaikutuksissa may be more common depending on register and domain.
