Why Do People Write “Placque”?
The incorrect spelling placque looks believable because English contains many words with unusual combinations of letters. People may also add an extra c because the word ends in -que and its pronunciation does not clearly reveal its spelling.
However, the standard spelling is simply:
P-L-A-Q-U-E
There is only one c.
So remember:
Plaque = one C
Not:
❌ Placque
Plaque Pronunciation
Plaque is pronounced approximately /plæk/.
It sounds similar to:
- black
- back
- lack
- track
This pronunciation can make the spelling difficult to guess if you have only heard the word spoken.
