lisätäkseen

Lisätäkseen is a Finnish verbal form derived from the verb lisätä, meaning "to add." It is the third infinitive (kolmas infinitiivi) formed by attaching the suffix -kseen to the verb stem, producing lisätäkseen. The form expresses purpose, roughly translating to "in order to add" or "to add."

Usage of lisätäkseen is mainly found in written, formal Finnish, including legal, administrative, and historical texts. It introduces purpose clauses or explanations of intended outcomes. It can appear after nouns such as tarkoituksena or as part of an infinitival clause describing why an action is taken. In everyday speech, speakers typically use other constructions, such as jotta plus a finite verb or alternative infinitive expressions, rather than lisätäkseen.

Formation and related forms: lisätäkseen is a product of the third infinitive pattern, and it denotes intention rather than a finished action. It is related to other long-form infinitives like kirjoittaakseen (to write in order to) and similarly formed compounds with different roots. The form is characteristic of more formal or literary Finnish and is less common in colloquial speech.

Examples:

- Päätös tehtiin lisätäkseen turvallisuutta. (The decision was made to increase safety.)

- Lainsäädäntömuutos tehtiin lisätäkseen läpinäkyyttä hallinnossa.
