stabiilne

Stabiilne is an Estonian adjective meaning stable or steady. It is widely used to describe conditions, systems, or states that resist change or that remain within predictable bounds. In everyday language, phrases such as "stabiilne olukord" (a stable situation) and "stabiilne ilm" (stable weather) illustrate its general use.

In science and engineering, stabiilne denotes properties or behaviours that persist despite disturbances. In mathematics and physics, stability describes how small perturbations affect a system’s long-term behaviour; in control engineering, a stable system produces bounded outputs for bounded inputs. In chemistry and materials science, a "stabiilne aine" or "stabiilne materjal" is one that does not rapidly degrade or react under typical conditions.

In economics and politics, stability often refers to the absence of large fluctuations in prices, growth, or governance, contributing to predictability and confidence. The noun form is stabiilsus, and related verbs include stabiliseerima (to stabilize) and stabiliseerimine (stabilization).

Etymology traces the word to the wider family of European terms for stability, via Germanic or Slavic routes into Estonian, ultimately from Latin stabilis. The form stabiilne is standard in modern Estonian orthography.

Notes: "Stabiilne" is primarily a descriptive adjective, used in compound terms such as stabiilne süsteem, stabiilne majandus, and stabiilne kliima. It does not designate a single, standalone concept but functions as a general descriptor across disciplines.
