Tehostaessa

Tehostaessa is a Finnish non-finite verb form derived from tehostaa, meaning to increase efficiency, strengthen, or boost. It functions as a gerundial or participial form used to describe a concurrent action or circumstance in formal writing. In practice tehostaessa introduces a subordinate clause indicating that the main action occurs while the process of intensification is taking place. It is closely related to tehostaen, the present active participle, and tehostettu, the past participle, but tehostaessa specifically carries a more circumstantial or temporal nuance.

Formation and use: Tehostaessa is formed by the verb stem tehosta- plus the essive- or -essa suffix. It cannot stand alone as a finite verb and is typically placed inside a sentence where the main clause states the primary action. The form often appears in technical, procedural, and descriptive prose to set the context of an action as enhancement occurs.

Usage in writing: The form expresses “as [something] is intensified” or “while [something] is enhanced,” functioning to articulate conditions that accompany the main statement. It is common in reports, manuals, and other formal texts.

Examples:

- Tehostaessa järjestelmän suojauksia, on varmistettava riittävä valvonta. (As the system protections are intensified, adequate monitoring must be ensured.)

- Tehostaessa energiatehokkuutta kustannukset voivat laskea. (As energy efficiency is increased, costs may decrease.)

Notes: Tehostaessa is mostly used in written, formal Finnish and may sound stilted in casual speech. The root tehostaa comes from teho “power” + -istaa, forming the sense of strengthening or optimizing.
