jatkuva

Jatkuva is a Finnish adjective meaning continuous, ongoing, or unbroken. It is formed from the verb jatkua, “to continue,” with the participle suffix -va. The related noun is jatkuvuus, which denotes continuity. The opposite form is epäjatkuva, meaning discontinuous, and epäjatkuvuus for discontinuity.

In everyday language, jatkuva describes states or processes without interruption. Examples include jatkuva valvonta (continuous monitoring), jatkuva kasvu (steady or persistent growth), and jatkuva seura (ongoing supervision). The word is commonly used across domains to emphasize duration, persistence, or seamless progression.

In mathematics and the natural sciences, jatkuva denotes objects or relations without breaks. A jatkuva funktio, or continuous function, is one where small changes in the input produce small changes in the output; in real analysis this concept is formalized through the definition of continuity. Jatkuvuus is central to many theorems and properties in calculus and analysis. In signal processing and engineering, jatkuva can describe continuous-time signals (jatkuva signaali) as opposed to discrete-time signals, which are characterized by sampling at separate time points.

The usage of jatkuva also extends to technology and industry, where it can describe ongoing operations, processes, or services that do not require explicit interruptions, such as jatkuva tuotanto (continuous production) or jatkuva toiminta (continuous operation). Overall, jatkuva conveys the notion of unbroken continuity across linguistic, mathematical, and practical contexts.
