Escutcheon (furniture) An escutcheon (pronounced /ÉªËskÊtÊÉn/, i-SKUCH-Én) is a general term for a decorative plate used to conceal a functioning, non-architectural item. Escutcheon is an old French word derived from the Latin word scutum, meaning a shield. Escutcheons are most often used in conjunction with mechanical, electrical, and plumbing components and fixtures where a pipe, tube, or conduit passes through a wall [or other material] surface.
If there is a blot on your escutcheon, you have damaged your reputation by doing something wrong. For the leaders, this is probably a blip rather than a blot on the escutcheon. Note: An escutcheon is a shield, especially a heraldic shield displaying a coat of arms.
