havaittava

Havaittava is a Finnish adjective meaning observable or detectable. It is formed from the verb havaita, “to perceive, notice,” with the present passive participle suffix -ttava, yielding “that can be perceived.” In English, it is commonly translated as observable or detectable.

In scientific and technical Finnish, havaittava describes phenomena, signals, results, or conditions that can be perceived or measured with available methods. The term is often used to indicate data or effects within a detection limit, or to emphasize that something is within perceptual reach under specified conditions.

Usage examples can illustrate its sense. An observable phenomenon is one that can be detected by measurement methods. The detectable strength of a device’s signal depends on temperature. The study’s results are observable only within a limited precision. Related concepts include havaittavuus, meaning detectability or observability, and havainto, meaning observation. The word is common in journals, manuals, and technical reports, where it helps distinguish what can be perceived under given conditions from what cannot.
