Heraldry is described in English using a specialised jargon called "Blazon" which is based on French words. Heraldry uses only bold, bright colors, called "tinctures", with special names. Gold, for instance, is called "Or". This word is often capitalised to distinguish it from the conjunction "or". Silver and white are sometimes treated as different colors, but in English Blazon both are called "argent". Some combinations of colors represent furs, and these have names that are only used in heraldry. There are a number of geometric shapes, called "ordinaries", that are used in heraldry, and each of these has a special name too. The shield may be divided in a number of ways, usually following the lines of the ordinaries.
