It was probably applied as a nickname, but in which sense is no longer clear, and the matter is further complicated by the fact that in some areas bunt meant ‘multicolored’ (its modern meaning is ‘colorful’).English : probably a metonymic occupational name for a maker of sieves, from Middle English bonte, bunte.
