What does flicker mean?
Flicker means, above all, instability of light. A candle, flame, or dying lamp that seems to waver between brightness and dimness is said to flicker, and by extension the word covers any rapid, slight variation — a screen image that flickers, a shadow that shifts, an expression that crosses someone's face for an instant. Because of this, flicker has become a natural way to describe fleeting inner states: a flicker of hope, a flicker of doubt, a flicker of annoyance. It can be used as both verb and noun, and its figurative uses give writing subtlety, suggesting something fragile or momentary that might vanish at any moment. In North America the word has a second life as the name of a striking woodpecker whose wing patches flash white in flight. Derived from Old English, where a related form described wavering movement, flicker belongs to a family of Germanic words about quick, light motion, and it remains one of the most evocative small words in everyday language.
To burn or shine unsteadily; to vary rapidly in brightness. More broadly, to move or occur with quick, slight, irregular movements.
"The candle flickered in the draft from the open window."
Usually intransitive; frequently used in progressive forms such as 'is flickering'.
An unsteady, wavering light or a brief, faint occurrence of something; also, chiefly in North America, a large woodpecker of the genus Colaptes.
"A flicker of hope crossed his face as the rescue team arrived."
'Flicker' as a countable noun often denotes a momentary trace of feeling or light rather than a sustained condition.
Used when referring to multiple instances of wavering light, or to more than one of the North American woodpeckers called flickers.
"Northern flickers are among the most widespread woodpeckers on the continent."
In North America, 'flicker' is also the name of a woodpecker whose flashing white rump patch makes it look like a flickering light as it flies.

Etymology of flicker
Flicker descends from Old English, where a closely related verb (flicorian) meant to flutter or move unsteadily, and it shares Germanic roots with continental cousins such as Dutch flikkeren and German flickern, which carry much the same sense of wavering light. The word has always combined ideas of lightness and irregularity, which is why it came to describe both unstable flames and quick, slight movements. Its use as the name of a North American woodpecker arose later, from the bird's flickering flight display. The exact earliest date of attestation in its modern form is uncertain, but the word was established in English well before the modern era.

How flicker is actually used
Flicker works equally for physical light sources and figurative, fleeting states such as hope, doubt, or a passing expression. In American birding vocabulary it also names a common woodpecker; outside North America this sense is rare. The verb is usually intransitive and appears most often in progressive forms ('was flickering').
