plaque




A plaque is a sign that memorializes a person or event, such as the plaque on a building noting the person it’s named after or the year it was built.

Plaque comes from the French word for “plate,” meaning not a dinner plate, but a little brass or tin plate that can be mounted on a wall. If you take a tour of Civil War battlefields, you’ll find that historical societies often use plaques to commemorate soldiers or particular events. Plaque is also a hard buildup in the body, like the plaque on your teeth that the dentist likes to scrape off.
