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.
