Plaque is the correct spelling in almost every modern writing situation. Plack is a real English word, but it is an old Scottish term for a small coin and is rarely used today.
I once read an award announcement that congratulated someone for receiving a “plack.” At first, I assumed it was just a typo. After checking a dictionary, I found something surprising. Plack is actually a real word, but it does not mean an award or a sign. It was the name of a small Scottish coin used hundreds of years ago.
The writer had meant plaque, which is the correct word for an engraved sign, commemorative plate, or even the sticky layer that forms on teeth. This mix-up explains why so many people search for plack or plaque. The two words look similar, but they have completely different meanings. A single missing letter can change what you are trying to say.
In this guide, you’ll learn the correct spelling, where each word came from, how British and American English treat the word, common mistakes to avoid, and plenty of real-life examples to help you use plaque correctly every time.
