essiivisestä

"Essiivisestä" is a Finnish inflected form typically identified as the elative singular of the adjective/noun essiivinen (or of the noun essiivi, "the essive"). In Finnish grammar the essive (essiivi) is a case that marks a temporary role, state or capacity, usually formed with the suffix -na/-nä (for example opettajana, "as a teacher"). The elative case (-sta/-stä) expresses motion or separation "from" something, origin, or the topical meaning "about" when used with certain verbs.

Morphologically, words ending in -nen (essiivinen) form the elative by replacing -nen with -sestä, yielding essiivisestä. The same surface form can derive from the noun essiivi through regular declension patterns. The form is used after verbs and constructions that require the elative, for instance kirje jostakin / kirjoittaa jostakin ("write about"), or verbs implying movement away: poistaa jostakin ("remove from").

Example: "Kirjoitin esseen essiivisestä sijamuodosta." — "I wrote an essay about the essive case form." In descriptive linguistics and language instruction essiivisestä appears in discussions of case functions, paradigms and comparative morphology.

Related forms include essiivi (base noun), essiivinen (adjective), essiivistä (partitive), and essiiviseen (illative). The term is mainly relevant within Finnish and Uralic case studies.
