What does flickering mean?
Flickering describes the rapid, irregular variation in brightness of a light or flame — the restless dance of a candle in a draft, a faulty lamp, or an aging screen. By extension, it applies to quick, slight movements, and figuratively to things that appear briefly and uncertainly, such as a flickering hope or a fleeting smile. The word derives from the verb 'flicker', which entered English in the medieval period, probably as an imitative formation echoing the jittery motion it names. Flickering is a vivid, sensory word: writers reach for it to create atmosphere, whether cosy and intimate in the glow of firelight or ominous in a stuttering fluorescent tube. Because it suggests both instability and fragility, it has become a natural metaphor for anything tenuous — courage, memory, signal, life itself. In ordinary usage it appears most often as a participle ('a flickering candle') or as a noun denoting an instance of such unsteady light or intermittent activity.
Present participle of flicker: to shine or burn unsteadily with rapid fluctuations in brightness, or to make quick, small, unsteady movements.
"The television picture kept flickering during the storm."
Most frequently used attributively ('a flickering flame') or in progressive constructions ('the lamp is flickering').
An instance of unsteady, wavering light, or a brief, intermittent occurrence of something such as an emotion or activity.
"He caught a flickering of amusement in her eyes before she turned away."
Characterized by unsteady, rapidly varying light or movement; wavering intermittently.
"They sat around the flickering campfire telling stories until midnight."
The flame doesn't just dance by chance — 'flicker' likely began centuries ago as an imitation of the very sound and motion a guttering flame makes.

Etymology of flickering
'Flicker' appears in Middle English as 'flikeren', meaning to flutter or move unsteadily, and is generally considered an imitative (onomatopoeic) formation of Germanic origin, echoing similar jittery-sounding verbs such as 'flitter' and 'flatter'. Some scholars connect it to the Middle English verb 'flicchen' ('to twitch'), which survives today in the unrelated-feeling 'flick'. The sense 'to shine unsteadily' developed from the earlier sense of unsteady movement, and the participle 'flickering' has carried this luminous meaning into modern English.
