opetuksellisista

Opetuksellisista is a Finnish grammatical form that appears in academic and educational contexts. It is the elative plural form of the adjective opetuksellinen, meaning didactic or instructional. In practice, opetuksellisista is used to indicate origin or source when referring to a plural noun phrase, such as didactic texts or materials.

Morphology and usage. The base adjective opetuksellinen (didactic) can take the usual Finnish plural forms when modifying a noun. In the nominative plural you would have opetukselliset tekstit (the didactic texts). To express “from the didactic …,” the elative plural suffix -ista/-istä is added, yielding opetuksellisista (e.g., opetuksellisista teksteistä, from the didactic texts). The same pattern applies with other nouns: opetuksellisten oppikirjojen (of the didactic textbooks) or opetuksellisista materiaaleista (from the didactic materials).

Context and tone. The term is primarily found in written Finnish, especially in reports, academic articles, and teaching materials. It does not denote a separate concept beyond the grammatical form, but it signals a focus on didactic content when discussing sources, materials, or perspectives in a plural elative context.

Example usage. Esimerkki: Opetuksellisista teksteistä löytyi useita selkeitä esimerkkejä. Another: Tutkimuksessa viitattiin opetuksellisista materiaaleista saatuun tietoon.
