No.
In modern English dictionaries, placque is not recognized as a standard word.
What Happens?
Most often, people write placque because:
- They misremember the spelling
- They assume it follows French spelling patterns
- They accidentally insert an extra “c”
Key Insight
If you’re writing in English, you should almost always use plaque, not placque.
Why People Confuse Plaque and Placque
At first glance, the confusion makes sense.
Similar Appearance
The words look nearly identical:
- plaque
- placque
The only difference is one extra letter.
Influence of French Words
Many English words borrowed from French contain unusual letter combinations.
Examples:
- antique
- boutique
- technique
Because of this, some writers mistakenly assume placque follows a similar pattern.
Typing Errors
Another common reason is simple keyboard mistakes.
When typing quickly, it’s easy to insert an extra letter without noticing.
The Spelling Logic Behind “Plaque”
Understanding the origin of the word helps.
Historical Background
The English word plaque comes from French and has been used for centuries to describe flat plates, signs, and similar objects.
Over time, English kept the spelling:
plaque
Not:
placque
Key Fact
English dictionaries, style guides, and academic sources consistently use plaque.
“Plaque” in Dental Health
One of the most common uses of the word appears in dentistry.
What Is Dental Plaque?
Dental plaque is a sticky film of bacteria that forms on teeth.
Examples

- Plaque buildup can cause gum disease.
- Dentists recommend flossing to reduce plaque.
Common Mistake

Another popular meaning involves signs and commemorations.
Examples

What Goes Wrong
Someone sees:
“Plaque”
Then later writes:

because it looks more familiar or “more French.”

Only one spelling is standard English:
Plaque
