Teollisilla

Teollisilla is a Finnish inflected form of the adjective teollinen, meaning "industrial." It is the plural adessive form, used when the noun it modifies is plural and the relation is locative, typically translating to "on/at/in industrial ..." in English. In Finnish, adjectives decline to agree with the noun in number and case, so teollisilla appears with plural nouns in the adessive case.

Teollisilla is commonly found in economics, geography, and journalism to describe processes, sectors, places, or groups associated with industry. For example, teollisilla aloilla means "in industrial sectors," teollisilla alueilla means "on industrial areas," and teollisilla yrityksillä means "at industrial companies." The form signals both plurality and a spatial or contextual relationship to industry.

It is distinct from teollisesti, which is the adverb meaning “industrially.” It is also distinct from other inflected forms of teollinen, which appear for different cases or numbers, such as teolliset (nominative plural) or teollisten (genitive plural).

In usage, teollisilla can emphasize a group or scope rather than a single entity, making it common in discussions about sectors, regions, or organizations tied to industry.
