Opastetusti

Opastetusti is a Finnish adverb meaning “in a guided manner” or “under supervision with a guide.” It describes situations where an activity is conducted with the presence of a guide who provides information, directions, and safety oversight. The word is formed from opastaa, meaning to guide, plus the adverbial suffix -sti.

Common contexts include cultural and educational settings, such as museum visits, heritage sites, or guided tours of cities and natural areas, where visitors receive explanations about exhibits, routes, and safety rules. It is also used in education to refer to supervised field trips or laboratory sessions, and in workplace or visitor-access contexts to indicate that access is restricted to accompanied groups.

Notes: The degree of guidance may vary; the guide provides information, answers questions, ensures safety, and confirms compliance with rules. In materials or signage, opastetusti may indicate that a guided option is available.
