Word Origin & History

mid-16c., originally "spread out" (hair), of unknown origin, perhaps from Du. vlederen. Related: Flared; flaring. The noun meaning "bright, unsteady light" is 1814, from the verb, which led to the sense of "signal fire" (1883). The notion of "spreading out in display" is behind the notion of "spreading
gradually outward" (1640s). Flare-up "a sudden burst" is from 1837. Flares "flared trousers" is from 1964.
