ratkaistakseen

Ratkaistakseen is a Finnish non-finite verb form derived from the verb ratkaista, meaning “to solve.” It functions as an infinitive of purpose, equivalent to the English expression “in order to solve.” In Finnish grammar it is described as a form of the second infinitive used to indicate the aim or intention behind an action. The form commonly appears in subordinate clauses or as a fronted non-finite clause that explains why or for what end the main action is undertaken.

Morphology and formation: Ratkaistakseen is formed by attaching a purpose-infinitive ending to the stem of ratkaista. Like other verb forms of this type, it is non-finite and carries no explicit subject; the subject is typically the same as the main clause’s subject when the form is used in isolation. The construction is productive in written Finnish and is found with many verbs that express intentional action.

Usage and Notes: Ratkaistakseen is more frequent in formal or descriptive writing than in casual speech, where shorter periphrastic expressions might be preferred. It enables precise expression of aim within a single sentence, for example: Ratkaistakseen arvoituksen hän keräsi lisätietoja (In order to solve the puzzle, he gathered additional information). It can be used with other purpose-infinitives, such as kirjoittaakseen (to write in order to) or opettaakseen (to teach in order to).

See also: Other Finnish purpose-infinitives share the same -akseen form, and are used to express intention across subordinate clauses. This form is one among several non-finite verb forms that enrich Finnish clauses by signaling purpose or motivation.
