Quick Definition

An idiomatic phrase meaning extremely quickly or instantaneously; light-speed metaphor used in poetry to convey swiftness, suddenness, or ephemeral moment through luminous temporal imagery emphasizing brevity and immediacy.

Detailed Definition
In a flash means extremely quickly, suddenly, or in an instant. In poetry, the idiom can mark swift perception, sudden memory, lightning-like change, danger, inspiration, or loss. The word “flash” gives the phrase visual brightness as well as speed, making it useful for epiphanies and shocks. A life may change in a flash; an image may appear and vanish. Poets can use it to contrast human desire for permanence with the brief, illuminating moments by which understanding often arrives.
Example
Example in poetry:
A lyric might say the swallows vanished in a flash beyond the orchard wall; In a battle poem, a sword can gleam in a flash before silence falls; The phrase in a flash means suddenly or very quickly; A poet may use it to sharpen pacing and make an image feel immediate.
Additional Notes
In a flash means very quickly, with brightness and speed compressed into one image. In poetry, it can describe sudden insight, lightning, memory, danger, disappearance, or emotional change. The phrase is useful because it carries both time and light: something happens almost instantly and vividly. Students should compare it with in a heartbeat and in a jiffy, noting that flash feels more visual, dramatic, and potentially violent.
