Plaque is 1.) an inscribed commemorative or ornamental tablet composed of a durable material such as metal or wood that is attached to a wall or other structure 2.) a sticky bacteria substance that attaches itself to teeth 3.) any patch on the body that is abnormal, such as a patch of psoriasis. The word plaque is derived from the Dutch word plakken, which means to stick.

Plack is often seen to mean any of the definitions of the word plaque, however, this is a misspelling. The only accepted meaning of the word plack is to describe a small copper coin used in Scotland in the 1400s and 1500s. The word plack comes from the Flemish word placke meaning a small coin.
