Ratkaistavat

Ratkaistavat is a Finnish adjective form derived from the verb ratkaista, meaning to solve or to determine. It is used to describe things that are to be solved or that can be solved, such as problems, tasks, equations, or questions. The term signals solvability and is commonly placed before a noun, or used predicatively after a linking verb.

Grammatically, ratkaistava is the base form; ratkaistavat is the plural nominative form used with plural nouns (for example, ratkaistavat ongelmat = the problems to be solved). Other inflected forms include ratkaistavan (singular genitive), ratkaistavien (plural genitive), and the partitive ratkaistavia used with quantities (paljon ratkaistavia ongelmia).

In everyday Finnish, ratkaistavat is often used in educational and scientific contexts to label tasks that require a solution. In mathematics and computer science the phrase can refer to solvability or decidability, such as solvable problems or decidable questions. The nuance is close to "to be solved" rather than merely "solvable" in a static sense.

Related terms include ratkaista, ratkaisu, ratkaisukyky (solvability), and ratkaisematon (unsolvable). The word illustrates how Finnish uses participial adjectives to connect linguistic description with mathematical or logical properties.
