flaunch

In heraldry, a flanch is a curved segment that encroaches on a heraldic field from either side. A related term, flasque, refers to a similar heraldic bearing that is narrower than a flanch. These terms are part of the broader system of heraldry, which is the art and science of using and displaying hereditary symbols, known as armorial bearings or coats of arms, to distinguish individuals, institutions, and corporations. Heraldry originated as a practical means of identification, especially in medieval warfare, where illiterate populations could recognize bold designs on shields and banners.12345
