Breytilegur

Breytilegur is an Icelandic adjective meaning changeable or variable. It describes things that can vary, fluctuate, or are not constant, such as weather, conditions, or data that may change over time. The word is used in everyday language as well as in scientific and technical contexts.

Etymology and related forms: Breytilegur is formed from the verb breyta, meaning to change, with the derivational suffix -ilegur. The core idea is “capable of change.” The related noun breyting means change, and breytileiki (variability) names the quality or degree of change. The term is common across domains such as meteorology, economics, and statistics, where variability is discussed.

Usage: In ordinary Icelandic, breytilegur describes things that are not fixed. For example, veðrið í dag er breytilegt, meaning the weather today is changeable. In data and research contexts, breytilegar niðurstöður are reported when results vary across samples or over time. The form adapts to gender and number in sentences, with breytilegur (masculine singular), breytilegur, breytilegt (neuter singular), or breytilegar (feminine plural) as appropriate.

See also and related terms: Related concepts include breytileiki (variability) and breyting (change). Antonyms and contrasts such as stöðugur or fastur convey constancy rather than changeability.

In summary, breytilegur is a core Icelandic term for describing anything that is not fixed and may change, a concept widely used in language, science, and everyday discourse.
