Congratulations is correct.
Congradulations is incorrect.

Comparison Table
| Word | Correct | Meaning | Example |
|---|---|---|---|
| Congratulations | Yes | An expression of praise or happiness for someone’s success | Congratulations on your promotion. |
| Congradulations | No | Common misspelling of congratulations | Avoid this spelling. |
The important difference is the letter d.
Congratulations contains t after “congra.”
Congradulations incorrectly changes that sound into a d.
Why Congratulations Is Correct
The correct word comes from congratulation, which has a long history in English.
Oxford Learner’s Dictionaries lists congratulation as the noun connected with the expression congratulations. It gives examples such as “Congratulations!” and “Congratulations on your exam results!”
The spelling follows the word family:
- congratulate
- congratulated
- congratulating
- congratulation
- congratulations
- congratulatory
None of these standard forms adds a d after “congra.”
That makes congratulations the reliable spelling for formal and everyday English.
Why Congradulations Is a Common Mistake
The confusion mainly comes from pronunciation.
The middle sound in congratulations can sound different to different speakers. Cambridge gives American pronunciation forms that include both a “tch” sound and a “dj” sound.
When people hear the word quickly, they may connect the sound with d and spell it as congradulations.
Another reason is the related word congratulate. Learners may remember the general sound but incorrectly insert a d while writing.
This is a spelling mistake, not a different English variation.
Dictionary Recommendations
Major English dictionaries support congratulations and congratulation, not congradulations.
Cambridge Dictionary lists congratulations as the expression used to show happiness about someone’s success.
Oxford Learner’s Dictionaries lists congratulation and gives congratulations as its common plural form.
Oxford also records congrats as an informal shortening of congratulations.
So, for standard English writing, choose congratulations.
Origin of the Word
The history of congratulation helps explain its spelling.
Oxford traces congratulation to Late Middle English and Latin congratulatio, from congratulari, meaning to show or wish joy. The Latin elements include con meaning “with” and gratulari meaning “show joy.”
Etymonline similarly traces congratulate to Latin congratulari, with the sense of wishing joy or expressing pleasure.
The word has therefore developed around the congrat spelling, not congrad.
Real Life Examples
Use congratulations when someone achieves an important goal.
At work
Congratulations on your promotion.
At school
Congratulations on graduating with honors.
For an award
Congratulations on winning the award.
For a new job
Congratulations on your new position.
As an engagement
Congratulations on your engagement.
For a wedding
Congratulations to the happy couple.
In a short message
Congratulations! You earned it.
These examples work in personal, academic, and professional communication.
Congratulations in Formal Writing
Congratulations is appropriate in professional writing when the situation calls for praise.
For example:
Congratulations on your well deserved promotion. We wish you continued success in your new role.
A shorter message can also be professional:
Congratulations on this outstanding achievement.
For formal documents, avoid the misspelled form congradulations because it can make your writing look careless.
Congratulations in Casual Writing
In casual messages, people often shorten congratulations to congrats.
For example:
Congrats on the new job!
Cambridge identifies congrats as an informal noun and exclamation.
Oxford also lists congrats as an informal shortening of congratulations.
Use congrats for texts, social media, and friendly conversations. Use congratulations when you want a more polished tone.
Common Mistakes
Here are some frequent spelling mistakes related to this word:
- Congradulations
- Congratualtions

Memory Trick
Use this simple trick:
Congratulations has “congratulate” inside it.
Think:

If you remember congratulate, the spelling of congratulations becomes much easier.
Congratulations vs Congratulation
There is a small grammatical difference between these forms.

However, in normal direct speech, people usually say:
Congratulations!
