Opettavia

Opettavia is the present active participle form of the Finnish verb opettaa, which means to teach. In Finnish grammar, present active participles formed with the -va/-vä endings function as adjectives or non-finite verb forms that modify nouns. Opettavia is the plural partitive form used when the modified noun is in the partitive case, or in phrases where the noun is in partitive, such as teaching-related nouns.

Usage-wise, opettavia describes agents or activities that teach. It can refer to people who teach, as well as methods, practices, or contexts that have a teaching function. The form conveys ongoing action or role rather than a static attribute. For example, opettavia menetelmiä means “teaching methods,” and opettavia kursseja can be rendered as “courses that teach.” The base form opettava is used in other grammatical contexts, for instance in singular or different case forms, as in opettava kirja meaning “an instructive book.”

In practice, opettavia tends to appear in phrases where the noun it modifies is in partitive or plural forms, reflecting its role as a participial modifier. As with other Finnish participles, its exact inflection depends on the noun and case being described.
