Beyond the definition

Imagine a river, always moving and never quite the same from one moment to the next. That's flux. It describes a state of continuous change or movement. Things in flux are unsettled and may be hard to predict. A period of political flux might mean governments are changing quickly, while the ups and downs of daily life can also feel like this.

The word comes from Latin and means "to flow." Think about how water moves; it is never still. You might say a company is in a state of flux after a merger, or that fashion trends are always in flux. Sometimes, flux also refers to the amount of something passing through an area, like magnetic flux in physics.
