The Quick Answer
If you are looking for the correct spelling, here it is: Congratulate is the only correct spelling in standard English.
The word requires a "t" in the middle, not a "d" (C-O-N-G-R-A-T-U-L-A-T-E). Spelling it as "congradulate" is universally considered a grammatical error in professional, academic, and casual writing. If you struggle with this word, you are not alone—it is one of the most frequently misspelled words in the American English language.
Correct Spelling
The definitive way to write this word.
C-O-N-G-R-A-T-U-L-A-T-E
Take note of the "t" following the "ra". This is the only accepted spelling in both American and British English dictionaries.
Common Misspellings
The most frequent errors writers make.
Congradulate
Using a "d" instead of a "t". The most common error.
Congradulations
Carrying the "d" error into the plural noun form.
Congratualate
Transposing the "u" and "a". A severe spelling error.
Why Is This Word Misspelled?
The linguistic breakdown of a notorious spelling trap.
The confusion stems from a cultural phonetic trap. In the United States, it is extremely common to playfully say "conGRADulations" to someone who is graduating. Because the "d" sound is closely linked to the concept of graduation (and the word "grade"), writers naturally assume the word itself contains a "d".
The Phonetic Trap
Spoken: kun-GRACH-oo-layt. The "t" makes a "ch" sound, which can sound harsh, leading people to substitute the softer "d" sound associated with graduates.
The Etymological Rule
Written: C-O-N-G-R-A-T-U-L-A-T-E. The Latin root 'gratus' demands the "t", regardless of the modern association with grades and graduations.
Correct Spelling Breakdown
Analyzing the word syllable by syllable.
con
Prefix (from Latin 'com-' meaning with or together)
grat
Root (from Latin 'gratus' meaning pleasing or thankful)
u
Connecting vowel
late
Suffix (verb ending)
Notice how the root "grat" contains the "t", just like in the words "gratitude" and "grateful." If you can spell grateful, you can spell congratulate.
Spelling Pattern
The Latin root assimilation rule at work.
To understand why the "t" exists, we have to look at Latin. The word comes from the Latin verb 'gratulari', which translates to "express joy." It is built from the root 'gratus', meaning "pleasing" or "thankful." There is no "d" in this root.
The prefix 'con-' (meaning "together") attaches to 'gratulari' to form 'congratulari'. When English adopted the word, it standardized the spelling with the "t" to match other English words sharing the same root, such as 'gratitude' and 'grateful'.
Noah Webster, the father of American English spelling, did not alter this word because its Latin roots were structurally essential. The "d" is an entirely modern, phonetic invention linked to academic contexts, not historical etymology.

How to Remember the Spelling
Memory tricks & mnemonics to lock it in forever.
1. The "T for Thanks" Mnemonic
The most effective trick. Say to yourself: "Use a T to give Thanks." Since you congratulate someone to thank them or acknowledge their success, you always use a T, not a D.
2. The "Gratitude" Trick
Think about the word "gratitude." Both "gratitude" and "congratulate" come from the same Latin root. If you can spell gratitude with a T, you can spell congratulate with a T.
3. The "Graduation" Warning
Remind yourself: "You graduate with a D, but you congratulate with a T." The words are separate, and mixing them is the root of the error.
4. The "No D in Success" Trick
Tell yourself: "There is no D in success, and there is no D in congratulate." This helps break the mental link between the word and the concept of grades.

Is 'congradulate' ever an accepted spelling?
No. In both American and British English, 'congradulate' is universally considered a misspelling. It is never accepted in formal writing, academic papers, or professional publications. The only correct spelling is 'congratulate' with a "t".
Why do people misspell it as 'congradulate'?
The primary reason is cultural. In the US, people frequently say "conGRADulations" to graduates. This creates a strong mental link between the word and the concept of "grades" or "graduating," leading people to incorrectly insert a "d" into the spelling.
What is the best memory trick for this word?
The most famous trick is: "Use a T to give Thanks." Since you congratulate someone to thank them or acknowledge their success, you always use a T. Another trick is remembering that "gratitude" and "congratulate" share the same root.
Is 'congratulate' spelled differently in the UK?
No. Unlike words such as 'color/colour' or 'center/centre', no spelling reform was applied to 'congratulate.' It is spelled with a "t" on both sides of the Atlantic.
What is the noun form of congratulate, and how is it spelled?
The noun form is 'congratulation.' It retains the "t" from the root verb. Interestingly, it is almost always used in the plural form, "congratulations," when offering praise.
What is the origin of the word congratulate?
It comes from the Latin word 'congratulari', which means 'to express joy.' It is formed from the prefix 'con-' (together) and 'gratulari' (to be glad), derived from 'gratus' (pleasing/thankful).
How do you use congratulate in a sentence?
You use it as an action verb when expressing praise for an achievement. It takes the preposition "on." For example: 'I want to congratulate you on your new job' or 'She congratulated the team on their victory.'
Is congratulate a formal word?
Yes, it is considered a formal and professional word. It is highly appropriate for business emails, academic writing, and official ceremonies, sounding much more polished than simply saying "nice job."
Does congratulate have a prefix and a root?
Yes. The prefix is 'con-' (a variation of 'com-' meaning 'together'), and the root is 'grat-' (from 'gratus' meaning 'pleasing' or 'thankful'). Together, they literally mean 'to share in joy.'
Can you congratulate someone for a failure?
No. Congratulate inherently implies praise and celebration of a success. Using it for a failure would be highly sarcastic or ironic. For failures, you would use words like 'console' or 'sympathize.'
