Placque is not a recognized English word.
You won’t find it in major dictionaries, style guides, academic publications, medical literature, or professional writing standards.
People often create the spelling accidentally because:
- Plaque contains an unusual letter arrangement
- French-derived words can appear confusing

- Writers rely on pronunciation instead of memorizing the spelling
Why Dictionaries Reject “Placque”
English dictionaries recognize only one standard form:

Any version containing an extra “c” is considered incorrect.

Why People Confuse Placque and Plaque
Several factors contribute to this common spelling mistake.
The French Influence
The word plaque comes from French.
Many English words borrowed from French retain spellings that don’t follow typical English patterns.
Examples include:
- Boutique
- Antique
- Unique
- Plaque
Because of this unusual structure, writers often add extra letters where they don’t belong.
Pronunciation Doesn’t Help
The word plaque sounds like:
“plak”
When people hear the word, they often assume the spelling should match the sound.
As a result, some write:
- Plack
- Placque
- Plaq
None of these spellings are correct.
Typing Habits
Sometimes muscle memory causes mistakes.
Writers familiar with words like:
- Acquire
- Acquaint
- Lacquer
may mistakenly insert an additional “c” when writing plaque.
How to Pronounce Plaque Correctly
The correct pronunciation is:
plak
Pronunciation Guide
| Word | Pronunciation |
| Plaque | plak |
The pronunciation remains the same whether you’re discussing:
- Dental plaque
- Award plaques
- Memorial plaques
- Arterial plaque
Common Pronunciation Mistakes

The correct pronunciation is short and simple.
