oppittu

Oppittu is a Finnish adjective and past participle meaning “learned” or “acquired through study or practice.” It describes knowledge, habits, or responses that have been developed rather than innate. The term is commonly used in educational, psychological, and scientific writing to distinguish what has been learned from what is natural or instinctive.

Etymology and form: Oppittu is derived from the verb oppia (to learn) and the past participle suffix -ttu, producing a passive participle used to modify nouns. It can appear before a noun to indicate acquired qualities or occur predicatively after a linking or auxiliary verb. While oppittu often describes cognitive or behavioral aspects, other forms of the same verb can describe people who have learned something.

Usage and nuance: The concept emphasizes learning-derived rather than innate characteristics. It is common in discussions of education, cognitive psychology, and linguistics. In psychology, the idea of learned versus innate responses is central, with learned fears or habits arising through conditioning or practice. Oppittu typically applies to abstract nouns like knowledge or behavior rather than to people directly, where other forms are used to denote a learner.
