Every day, millions of people reach for this word — to celebrate a friend’s promotion, toast a graduate, or cheer someone across a finish line. And every day, a surprising number of them spell it wrong. So which is it: congratulations or congradulations?
The confusion is more common than most people realize, and it does not just affect language learners. Even fluent English speakers trip on this one. This article gives you a clear, research-backed answer, explains why the mistake happens so often, and shows you exactly how to use the word correctly in every context — from text messages to formal letters.
Congratulations or Congradulations – Quick Answer
Congratulations is the only correct spelling in English. The word congradulations is a misspelling and should never appear in formal, professional, or academic writing.
The correct spelling is: C-O-N-G-R-A-T-U-L-A-T-I-O-N-S
The key letter to watch is the “t” — not a “d” — in the middle of the word. Think of it this way: the word contains GRAT, as in grateful or gratitude. That mental hook alone can save you from making this mistake again.
Examples:
Correct:
- Congratulations on your new job!
- We extend our sincere congratulations to the entire team.
- Congratulations — you passed the bar exam!
Incorrect:
- ~~Congradulations on your graduation!~~
- ~~Sending my congradulations to the happy couple.~~
Quick tip: If you can remember congrats (the informal short form), you already know the word uses a “t.” Nobody says congrads — and the same logic carries straight into the full word.
The Origin of Congratulations or Congradulations

The word congratulations has deep Latin roots. It entered English in the mid-15th century, borrowed via French from the classical Latin verb congrātulārī, which means “to wish joy together.” This verb is a compound of two parts:
- com- (together, with)
- grātulārī (to give thanks, to show joy) — from gratus, meaning pleasing or agreeable
That root, gratus, is the same one behind grateful, gratitude, and gratuity. This family connection is your clearest clue: the correct spelling always contains GRAT, not GRAD.
The earliest recorded use in English literature dates to 1591, in John Harington’s translation of the Italian epic Orlando Furioso. By the 16th and 17th centuries, the word had settled firmly into everyday English usage to mark achievements, happy events, and celebrations.
Why does “congradulations” exist?
The misspelling did not come out of nowhere. There are two solid reasons it persists:
- Pronunciation blur: In fast, natural speech, the “t” in congratulations often softens and blends into a sound that resembles a “d.” The brain hears congra-d-ulations and the hand writes what the ear heard.
- The graduation pun: Over time, congradulations became a deliberate, playful wordplay combining congrats and grad (as in graduate). You have probably seen it on graduation cards, banners, and social media posts. This intentional use made the spelling feel familiar and almost legitimate to many readers — even though it remains incorrect outside of that humorous context.
The existence of this pun is probably the biggest reason the misspelling spread so widely online. What started as a joke became, for many people, a genuine source of spelling confusion.
British English vs American English Spelling
One of the most common questions people ask when facing a spelling doubt is whether the two major varieties of English handle it differently. With congratulations, the answer is unusually simple: there is no difference at all.
Both British English and American English use the exact same spelling: congratulations. There are no regional variants, alternate accepted forms, or dialect exceptions to worry about. Whether you are writing from London, New York, Sydney, or Toronto, the spelling stays the same.
Comparison Table
| Feature | British English | American English |
|---|---|---|
| Correct spelling | congratulations | congratulations |
| Accepted misspelling | ❌ None | ❌ None |
| Informal short form | congrats | congrats |
| Playful graduation pun | congradulations | congradulations |
| Used in formal writing | ✅ Yes | ✅ Yes |
The consistency across both dialects makes this one of the easier spelling rules to memorize: there is only one answer, everywhere.
Which Spelling Should You Use?
The answer is always congratulations — but how and where you use it can vary depending on your audience and the occasion.
Based on your audience:
Formal writing (emails, letters, reports, official announcements): Use congratulations in its full, correct form. Abbreviations and casual variants are out of place here.
“Please accept my warmest congratulations on your appointment as Director of Operations.”
Casual writing (text messages, personal cards, social media captions): Congratulations still works perfectly. You can also use the shorthand congrats without any loss of meaning.
“Congrats on the new house!! So excited for you 🎉”
Graduation-themed content (banners, cards, party decorations): The pun congradulations is widely understood and accepted here because the humor is intentional and the context makes it obvious. Just be aware that it reads as a joke, not standard spelling.
Professional social media (LinkedIn, company blogs, press releases): Stick to congratulations. Even in a relaxed digital tone, correct spelling signals credibility and attention to detail.
