Tehostavaan

Tehostavaan is a Finnish grammatical form derived from the verb tehostaa, meaning to enhance or boost. It is the illative singular form of the present active participle tehostava, which functions as an adjective meaning “enhancing” or “that enhances.” The illative form tehostavaan is used to indicate direction toward a purpose or use, and it appears most often in noun phrases describing intended use or objective.

In practice, tehostavaan occurs mainly in technical or formal Finnish. Common constructions include tehostavaan käyttöön (for enhanced use) and tehostavaan tarkoitukseen (for the purpose of enhancing). For example: Laite on suunniteltu tehostavaan käyttöön, meaning “The device is designed for enhanced use.” Ohjelmisto on kehitetty tehostavaan tarkoitukseen, meaning “The software was developed for the purpose of enhancing performance.”

Notes: As a case-inflected form, tehostavaan agrees with the noun it modifies in number and case. The base tehostava is more frequently used in direct attributive position, while tehostavaan is specifically the illative singular form. The construction is common in written or technical Finnish and may be less frequent in everyday conversation.
