edetessä

Edetessä is a Finnish non-finite verb form that functions as a present adverbial participle derived from the verb edetä, meaning "to progress." It expresses that a secondary action occurs concurrently with the action of the main clause, roughly translating to "as [something] progresses" or "while [something] is progressing." It is formed by attaching the suffix -essa or -essä to the verb stem; for edetä the form is edetessä. The form is used primarily in written Finnish, including journalism, essays, and narrative prose, although it can appear in more formal spoken language as well.

The function of edetessä is to provide temporal or circumstantial context without introducing a finite verb. It signals simultaneity and can sometimes replace a subordinate clause introduced by kun or kunnes.

Examples:

- Edetessä tutkimus paljasti uusia löytöjä. (As the research progressed, it revealed new findings.)

Variants: Like other adverbial participles, edetessä belongs to the same family as lukiessaan, karttaaessa, etc., with the -essa/-essä suffixes adapting to the verb stem.
