flash

1387, from flasken (c.1300) "to dash or splash" (as water), probably imitative. Sense of "sudden burst of light or flame" is 1548, as is the noun. Meaning "photographic lamp" is from 1913. Flashy "showy, cheaply attractive" is first recorded 1690. Flashlight, Amer.Eng. for "electric torch," is from 1919. Flashback is 1916 as a plot device in novels or movies; 1960s as a type of hallucination. Flasher "male genital exhibitionist" is 1960s, though meat-flasher in this sense was attested in 1890s. Flash in the pan (1809) is from old-style guns, where the powder might ignite in the pan but fail to spark the main charge.

Flash

Flash\, v. i. [imp. & p. p. Flashed; p. pr. & vb. n. Flashing.] [Cf. OE. flaskien, vlaskien to pour, sprinkle, dial. Sw. flasa to blaze, E. flush, flare.]

1. To burst or break forth with a sudden and transient flood of flame and light; as, the lighting flashes vividly; the powder flashed.

2. To break forth, as a sudden flood of light; to burst instantly and brightly on the sight; to show a momentary brilliancy; to come or pass like a flash.

Syn: Flash, Glitter, Gleam, Glisten, Glister.

Usage: Flash differs from glitter and gleam, denoting a flood or wide extent of light. The latter words may express the issuing of light from a small object, or from a pencil of rays. Flash differs from other words, also, in denoting suddenness of appearance and disappearance. Flashing differs from exploding or disploding in not being accompanied with a loud report. To glisten, or glister, is to shine with a soft and fitful luster, as eyes suffused with tears, or flowers wet with dew.
