A standard heraldic blazon allows for a design to be reconstructed, at least in general outline. It describes the field first, followed by the device, if any, placed upon that field (though halving and quartering can complicate this). Adjectives, such as tinctures and attitudes, follow the noun. Thus, the rather fiddly arms of Sir Aglavale (‘Purpure a semy of crosslets or a lion passant guardant argent armed and langued gules‘) break down as follows.
Purpure = A purple background…
a semy = …with a repeating pattern…
of crosslets or = …of small gold crosses.
a lion passant = A walking lion…
guardant = …looking at the viewer…
argent = …in white or silver…
armed and langued gules = …with claws, teeth and tongue in red.
