Blazon is a less commonly used synonym of the more familiar coat of arms. Both centuries-old terms refer to heraldic designs, symbols, and other imagery (think crosses, lions, stripes, etc.) that typically appear on banners, shields, armor, and elsewhere. The verb form of blazon meaning “to depict heraldic figures or designs in drawing or engraving” and emblazon, “to inscribe or adorn with or as if with heraldic figures or designs,” came into use around the same time in the late 1500s, from the French spoken in medieval England. (The word heraldry, also ultimately from Anglo-French, came into use then too.) Emblazon still refers to marking something with an emblem of heraldry, but it is now more often used for adorning or publicizing something in any conspicuous way, whether with eye-catching decoration or colorful words of praise.
