Yhtiöillä

Yhtiöillä is a plural inessive/adessive form of the Finnish word yhtiö, meaning companies or corporations. In Finnish grammar, the suffix -llä (in the plural form -llä) indicates location, presence, or association, so yhtiöillä is used to refer to “at the companies,” “with the companies,” or simply “the companies” in a context that emphasizes plural entities. For example, in a sentence about obligations or activities, yhtiöillä can mean that the companies themselves have certain duties or rights.

In common usage, yhtiö refers to a business entity with legal personality. The most prevalent formal structure in Finland is the osakeyhtiö (Oy), a limited liability company. Other corporate forms include avoin yhtiö (Ay), a general partnership; and kommandiittiyhtiö (Ky), a limited partnership. While yhtiö is often used broadly to denote any of these entities, many everyday references also use yritys or yritykset to speak of companies in general.

Yhtiöt are regulated by Finnish corporate law and must register in the Finnish Trade Register. They are separate legal persons capable of owning property, entering into contracts, and suing or being sued in their own right. A key practical identifier is the business ID (Y-tunnus) assigned upon registration. The plural form yhtiöillä appears in legal, economic, and media contexts when discussing multiple companies or the collective activities and obligations of corporate entities.

Overall, yhtiöillä functions as a grammatical tool to discuss several companies together, while yhtiö itself denotes the entity type used in Finnish corporate discourse.
