Opituksen

Opituksen is the genitive singular form of the Finnish noun opitus. Opitus refers to instruction, doctrine, or teaching, particularly in formal, historical, or religious contexts. In contemporary Finnish, opitus is relatively rare; the everyday term for teaching or instruction is opetus, whose genitive form is opetuksen. Therefore opituksen tends to appear in academic, ecclesiastical, or historical texts when signaling the content or system of teaching belonging to a person, institution, or tradition, for example kirkon opituksen periaatteet (the principles of the church’s doctrine).

The word opitus is part of Finnish abstract noun formation with the suffix -itus, which conveys a state, practice, or body of knowledge. It is usually considered more archaic or specialized than opetus, and it is most often found in discussions of doctrine, scholastic tradition, or doctrinal summaries rather than everyday language. In modern usage, opitus is typically contrasted with opetus (the act or process of teaching) and with oppi (doctrine or belief) to distinguish between content, process, and system of ideas. The form opituksen appears primarily when indicating possession or association, such as in references to a specific set of teachings or doctrinal framework.
