Congratulations is the correct spelling, while congradulations is a common spelling mistake.
The confusion happens because the word sounds as if it may contain the word “grade,” which can lead people to add a d after “congra.”
However, the correct spelling has no d in that position: congratulations. This word is used to praise someone for an achievement, success, special event, or happy occasion.
In this guide, you will learn the meaning, origin, pronunciation, spelling rules, common mistakes, and everyday uses of congratulations.
You will also learn whether British and American English use different spellings and how to remember the correct form.
Quick Answer

Congradulations is incorrect.
The word congratulations is used to express praise or good wishes when someone achieves something or experiences a happy event.
Correct
Congratulations on your new job!
Congratulations on passing your exam!
Congratulations to the happy couple!

The Origin of Congradulations or Congratulations
The correct word congratulations comes from the Latin verb congratulari, meaning “to wish joy” or “to express joy together.” It entered English through French and developed into the English word congratulate. The noun congratulation comes from the same word family.
The word is connected to the Latin idea of sharing joy with another person. This meaning is still clear today because people say congratulations when they celebrate someone else’s success or happiness.
The spelling congradulations developed as a common spelling error. One reason is that the middle part of the word can sound unclear when spoken quickly. Some people also associate the word with grade, especially when talking about school success.
For example, someone may think:
“You got a good grade, so the word must be congradulations.”
But this connection is incorrect.
The word is spelled:
congratulations
not:
congradulations
There is no d after congra.
The correct word family includes:
- congratulate
- congratulated
- congratulating
- congratulation
- congratulations

Think:
congratulate → congratulation → congratulations

Remember that pronunciation is not a reliable guide for every English spelling.
Write:
congratulations
Not:
congradulations
