kutsuttaessa

Kutsuttaessa is a Finnish non-finite verb form derived from the verb kutsua. It is used to express an action occurring at the moment of being called or invited, functioning as an adverbial participle. In grammar terms, it is part of the family of adverbial participles formed with the suffix -tta- plus an -essa/-essä ending, yielding kutsuttaessa. The form denotes simultaneity or a conditional context and is typically translated as “when called” or “upon being called.”

Kutsuttaessa is most common in formal or technical Finnish, such as manuals, procedural descriptions, and legal or regulatory language. In everyday speech, speakers tend to use more explicit temporal clauses like kun kutsutaan or kun kutsutaan, or other simpler constructions rather than the adverbial participle form. Because it is a non-finite form, kutsuttaessa does not itself specify a subject; the subject is taken from the surrounding clause, and the main clause presents the action that follows or accompanies the call.

Examples:

- Kutsuttaessa funktiota ohjelma käynnistyy. (When the function is called, the program starts.)

- Kutsuttaessa järjestelmä tarkistaa käyttäjän oikeudet. (When invoked, the system checks the user’s permissions.)

Notes:

- The form is versatile for concise, stack-safe descriptions in documentation or specifications.

- It can appear at the beginning or within a sentence to set the temporal or conditional context for the main clause.
