Valmond was alive to it all, almost too alive, for at first the flamboyancy of his spirit touched him off with melodrama.
1832, first used of a 15c.-16c. architectural style with flame-like curves, from French flamboyant "flaming, wavy," present participle of flamboyer "to flame," from Old French flamboier (12c.), from flambe "flame," from flamble, variant of flamme, from Latin flammula (see flame (n.)). Extended sense of "showy, ornate" is 1879. Related: Flamboyantly.
