opettavaiseen

Opettavaiseen is a Finnish adjective form meaning educational or instructional. It is the illative singular form of the stem opettavaisen that arises from the base adjective opettavainen, which describes something designed to educate or teach. In Finnish, adjectives agree with the noun they modify and take inflected endings that correspond to the noun’s case and number. Opettavaiseen appears when the noun it describes is in the illative case, commonly in phrases such as opettavaiseen tarkoitukseen (for educational purposes) or opettavaiseen käyttöön (for instructional use).

Usage and nuance: The term is typically found in educational materials, curricula, guidelines, and policy language where a resource, action, or approach is characterized by its educational intent or function. It does not stand alone as a separate concept; rather, it functions as the illative form of the adjective describing purpose or mode of use. Because it follows standard Finnish adjective inflection, opettavaiseen can combine with nouns across the illative case and, in other contexts, its other forms align with the normal declension patterns of adjectives.

Related forms and notes: The lemma of the word is opettavaisen, opettavaisen, or other inflections depending on the noun it accompanies. The root concept is connected to the verb oppaettaa/oppia in its sense of teaching or instructing, and is related to other educational terms such as opettaja (teacher), opettaminen (teaching), and opettavaisuus (educational value).
