ratkaisten

Ratkaisten is a Finnish non-finite verb form derived from the verb ratkaista, meaning "to solve." It functions as a converb or present active participle and is used to express an action that accompanies or enables the action of the main clause. The sense is typically that the solving of something is the means or manner by which the main event occurs, and the subject of the converb is ordinarily the same as the subject of the main clause.

Formation and usage: The converbal form is one of several non-finite verb forms in Finnish. It is used without a separate subject and connects to the main verb, often in written or formal prose. It can denote means, cause, or simultaneous action. It is less common in everyday speech but widely understood in standard Finnish.

For example: Ratkaisten ongelman, tiimi eteni. This can be translated as "Solving the problem, the team progressed," with the implied subject of the converb matching the main clause's subject.

Related forms: The present active participle in a modifying role can be expressed with the form ratkeiseva, meaning "solving" as a modifier. The past participle 'ratkaissut' means "solved," while the noun form 'ratkaiseminen' denotes the act of solving.
