Rozvrení

Rozvíření is a noun used in Czech and Slovak to describe the act or process of stirring up or disturbing a substance or situation. In physical contexts it refers to the onset of motion and mixing in a liquid or gas, often leading to turbulence or chaotic flow. In metaphorical usage it denotes the act of arousing or amplifying opinions, emotions, or social tensions.

Etymology: Rozvířit means to swirl up or stir up, with the prefix roz- indicating a change from a calm to a more active state, and the root vířit meaning to swirl or whirl. In standard orthography the form is rozvíření; ASCII renderings such as rozvrení may appear in non-diacritic texts, but correct spelling includes í.

Context and examples: In physics and engineering, rozvíření of a stream or mixture describes turbulence and mixing efficiency. In meteorology, rozvíření of dust or aerosols by wind affects visibility and air quality. In chemistry, mixing and agitation cause rozvíření of reactants. In sociology or political science, rozvíření nálad or rozvíření veřejného mínění denotes the deliberate or incidental stirring of public sentiment. The term is common in technical writing and journalism; related terms include turbulence (turbulence), víření (swirling), and míchání (mixing).
