Jatkuvasi

Jatkuvasi is a hypothetical linguistic construct used in discussions of Finnish grammar to illustrate how adverbs could be formed from adjectives to convey manner of action with a sense of continuity. The term combines the Finnish adjective jatkuva meaning “continuous” with a proposed adverbial suffix -si, modeled on standard adverb formation such as -sti (for example, nopeasti from nopea). Jatkuvasi would translate roughly as “in a continuous way” or “continuously.” It is not recognized as a standard or productive form in modern Finnish and is rarely used outside theoretical examples.

In usage, proponents frame jatkuvasi as a thought experiment to explore how language could encode duration directly in manner adverbs, distinct from standard adverbs like jatkuvasti (continuously), which uses the regular adverb formation. Example: Toiminta eteni jatkuvasi, ennen kuin projekti saatiin päätökseen. The sentence is given as a hypothetical illustration rather than an accepted grammatical construction.

Reception among linguists is mixed. Many scholars view jatkuvasi as a useful educational tool for examining morphology and word formation, while others argue that it would complicate Finnish grammar without providing clear communicative benefits and that it blurs established adverbial forms such as -sti and -vasti.
