epävakailla

Epävakailla is a Finnish verb derived from the adjective epävakaa, meaning "unstable" or "inconsistent." As a verb, it denotes being unstable, fluctuating, or behaving inconsistently, and is commonly used to describe phenomena such as weather, moods, political situations, or markets.

Etymology and formation: the base adjective epävakaa (epa- as a negating prefix + vakaa "stable") is converted into a verb form to express a state or tendency to vary. The infinitive form is epävakailla; in everyday use it appears in contexts indicating irregular change or lack of steadiness.

Usage: Epävakailla is typically intransitive and applied to inanimate and abstract subjects (e.g., sää, mieliala, tilanne). It conveys that conditions are subject to change rather than remaining constant. Example sentences include "Sää epävakailee" (The weather is unstable / The weather is fluctuating) and "Markkinat ovat epävakaat, kurssit voivat epävakailla" (Markets are unstable; prices may fluctuate).

Related terms: epävakaa (unstable, adjective), vakaa (stable), vakailla (to be steady, less common). The verb is part of everyday Finnish vocabulary for describing variability and unpredictability.
