suurennettaessa

Suurennettaessa is a Finnish non-finite verb form derived from suurentaa, meaning to enlarge or magnify. It functions as an adverbial participle with the meaning “when enlarging” or “upon enlargement,” and is used to indicate that another action occurs in conjunction with the enlargement or under its conditions. The form is created from the verb stem suurenta- plus the suffix -ttaessa, producing a present adverbial participle that connects clauses without a finite verb.

In usage, suurennettaessa introduces a dependent clause or note describing considerations relevant during the enlargement process. It is common in technical, scientific, and instructional writing, especially in manuals, captions, and figure descriptions. For example, as a statement in a manual: “Suurennettaessa kuvaa voidaan havaita kohinaa,” meaning “When enlarging the image, noise may be observed.” The construction can often be translated into English as “When enlarging” or “Upon enlargement.”

Related forms include suurennus (enlargement) and suurennettu (enlarged). The form is primarily found in formal or written language and is less common in everyday spoken Finnish, where shorter or more explicit clauses are typically preferred.

In summary, suurennettaessa is a technical grammatical form used to express simultaneous action during magnification, most frequently seen in manuals, scientific texts, and figure descriptions.
