opetettu

Opetettu is a Finnish linguistic term used as the past passive participle of the verb opettaa, meaning to teach. As an adjective, it indicates that teaching or instruction has taken place and is used to describe knowledge, skills, or materials that have been taught to someone or to a group. The form is built from the stem opet- with the suffix -ettu, and, like other Finnish participles, it agrees with the noun it modifies in number and case.

In usage, opetettu describes things that have received instruction. For example, kurssilla on opetettu lukemaan ja kirjoittamaan (the course has taught reading and writing). Tarkoituksena on express that teaching has occurred, often with recipients expressed through other sentence elements. The plural form can yield phrases like opetetut taidot (the taught skills).

Related forms include opettava (the opposite sense as a present-active adjective) and opettaja (teacher). The corresponding future passive participle is opetettava, meaning something that is to be taught or to be instructed. Other related terms are opetus (instruction/teaching) and opettaminen (teaching as a process).

Opetettu is widely used in educational contexts to convey that instruction has already occurred, whether referring to skills, knowledge, or materials that have been conveyed to learners.
