Tehtyjä

Tehtyjä is a Finnish grammatical form that functions as the plural partitive of the past passive participle tehty, which comes from the verb tehdä meaning “to do” or “to make.” The form is used to describe nouns that have been completed or produced, emphasizing the result rather than the agent of the action.

In practice, tehtyjä is attached to a plural noun in the partitive case. This construction is common when talking about quantities or categories of things that have already been done or made, without specifying who performed the action. For example, tehtyjä töitä means “work that has been done,” tehtyjä virheitä means “mistakes that have been made,” and tehtyjä ratkaisuja means “solutions that have been devised.” The emphasis is on the completed state of the items described.

Morphologically, tehtyjä derives from tehty, the past passive participle of tehdä. The plural partitive ending -jä is used to modify a plural noun in partitive (such as töitä, virheitä, ratkaisuja). This form contrasts with the related adjective-teptide tehty, which may modify nouns in other cases or numbers (for example, tehdyt työt, meaning “the tasks that have been done”). The choice between tehtyjä and tehdyt depends on the case and number of the noun being described.

Usage notes: tehtyjä typically signals completed results and is common in everyday language, journalism, and written Finnish when referring to multiple items that have already been produced or completed. It is not used as a standalone noun; rather, it serves as a modifier that aligns with the partitive plural noun it accompanies.
