flicker
UK: ˈflɪkə | US: ˈflɪkər
vi. to burn or shine unsteadily, with a wavering light
vi. to move quickly and irregularly
n. a brief, unsteady light or movement

The word "flicker" originates from Middle English flikeren, related to Old English flicorian (to flutter) and Old Norse flökra (to flicker). The root "flick" suggests rapid, light movement, while the suffix "-er" denotes repetitive or ongoing action. The word evolved to describe both the visual effect of unsteady light (like a flame) and quick, irregular motions (e.g., a bird's wings). Its modern usage retains these dual meanings, often implying brevity and instability.
