ratkaistava

Ratkaistava is a Finnish adjective meaning solvable or to be solved. It is derived from the verb ratkaista, “to solve” or “to decide,” with the present-participle suffix -va. The term describes a property of a thing or situation that can be resolved or determined, such as a problem, a task, an equation, or a question. In formal or technical writing it is common to indicate that a solution exists or is attainable by using ratkaistava to label the subject.

Usage and examples: The phrase ratkaistava ongelma (a problem to be solved) is frequently used in planning, mathematics, and logic. An equation described as ratkaistava refers to one that has a solution. The word can also appear in statements such as “Ongelma on ratkaistava,” meaning the problem must be solved. As an attributive adjective, ratkaistava agrees with the noun in number and case, for example ratkaistavat tehtävät (solvable tasks) or ratkaisun mahdollinen este (the possible obstacle to a solution, in context).
