opastetuilla

Opastetuilla is a Finnish grammatical form derived from the verb opastaa, meaning to guide. It is the past passive participle opastettu (guided) in the adessive plural form opastetuilla, and it functions as an adjective describing plural nouns in contexts involving guided experiences or places. In practice, opastetuilla describes a state or characteristic “on guided” or “in guided” settings, such as guided tours or guided locations.

Usage and context

The form is common in tourism, museums, cultural events, and signage. It appears in phrases that indicate that a service, route, or area is led by a guide. It is always used with a noun in the adessive plural, for example with kierroksilla or paikoilla.

Examples

Opastetuilla kierroksilla vierailijat kuulevat oppaan selitykset. (On guided tours, visitors hear the guide’s explanations.)

Opastetuilla paikoilla on nähtävillä lisäkylttejä ja tietolaattoja. (At guided sites, there are additional signs and information plaques.)

Many signs and brochures use the form to signal that the experience is led by a guide rather than self-guided.

Related forms and notes

Opastettu is the basic past passive participle; opastetut is the nominative plural. Finnish adjectives and participles agree in case and number with the nouns they modify, so opastettu forms change to opastetussa, opastetuilla, opastetuilla, etc., depending on grammatical case. Opastetuilla is not a standalone verb form but a descriptive participial adjective used in conjunction with plural nouns in the adessive.
