Plaque vs. Plack – Which is Correct?
The correct spelling is plaque, referring to a flat, thin piece of material, a commemorative plate, or a film of bacteria on teeth. Plack is a common misspelling and holds no meaning in standard English. Always use “plaque” for all intended contexts to ensure clarity and correctness in your writing.
Plaque or Plack – Which is Correct?
The distinction between “plaque” and “plack” is straightforward: plaque is the universally accepted and correct spelling in English, while plack is an erroneous variant. This common misspelling often arises from phonetic confusion, as the “que” ending in “plaque” produces a “k” sound. However, despite the similar sound, “plack” is not recognized as a legitimate word in dictionaries or standard usage.
The Best Trick to Remember the Difference
To easily remember the correct spelling, think of the “que” in plaque as a unique identifier. Many English words of French origin, like “boutique,” “antique,” and “technique,” also end with “que” for a “k” sound. Associate “plaque” with these other words to reinforce that the “que” ending is correct, not a simple “ck.” A simple mental check: if you’re referring to dental film or a commemorative plate, it always ends with “que.”
| Word | Part of Speech | Meaning | Example |
|---|---|---|---|
| Plaque | Noun | 1. A thin, flat plate or tablet, often decorative or commemorative. 2. A sticky film of bacteria that forms on teeth. 3. An abnormal patch on a body part. | The bronze plaque commemorated the building’s founder. |
| Plack | Incorrect | A common misspelling of “plaque.” | Using “plack” instead of “plaque” is incorrect. |
How to Use Plaque
The word “plaque” is a versatile noun with several distinct meanings, primarily referring to a thin, flat object or a bacterial film. Its usage is generally formal or technical, depending on the context. When referring to a commemorative item, it evokes a sense of respect and permanence. In a medical or dental context, it is a precise term for a biological accumulation.

Example 2: Regular brushing and flossing are essential for removing dental plaque and preventing cavities.
Example 3: Doctors observed an accumulation of amyloid plaque in the patient’s brain scans.
What are the different forms of Plaque?
“Plaque” is a noun and primarily changes form through pluralization.
- Singular: Plaque (e.g., “one plaque”)
- Plural: Plaques (e.g., “several plaques”)
The word does not have verb forms, adjectival forms, or adverbial forms derived directly from it in standard usage.
Etymology of the word Plaque
The word “plaque” entered the English language from French in the 17th century. It derives from the Middle French plaque, meaning “a plate,” which itself came from the Dutch plak or German Plakke, both referring to a flat piece of metal or wood. The dental meaning of “plaque” evolved much later, gaining prominence in the late 19th and early 20th centuries as scientific understanding of oral health advanced.
Related Concepts
Understanding broader linguistic concepts can help clarify why certain words are spelled the way they are and why misspellings occur.
- Phonetic Misspellings: These occur when a word is spelled exactly as it sounds, rather than adhering to its conventional orthography. “Plack” is a classic example, as the “que” in “plaque” sounds like “k,” leading to the incorrect phonetic spelling.
- Loanwords: Many English words, including “plaque,” are borrowed from other languages (in this case, French). These words often retain their original spellings, which can sometimes appear irregular to English speakers who are unfamiliar with the source language’s phonetic rules (e.g., the “que” ending).
