Definition
Flickering describes something that is unsteady and wavering, like a flame or light. Imagine a candle in a draft or an old television screen. It suggests an intermittent or fluctuating quality. The effect is often visually distracting or unsettling. It can also be used metaphorically to describe something unstable or unreliable, such as a hope or an emotion. It differs from 'blinking', which is more regular.
