If you are wondering whether to write guarantee or guarentee, choose guarantee. The word can function as both a verb and a noun, and it commonly refers to a promise, assurance, or commitment that something will happen or that a product or service will meet certain conditions.
Quick Answer: Guarantee or Guarentee?
The correct spelling is guarantee.

How Do You Pronounce Guarantee?
In American English, guarantee is commonly pronounced approximately:
GAR-un-TEE
The pronunciation can make the spelling confusing because the spoken form does not clearly reveal every letter.
That is one reason people sometimes write guarentee instead of guarantee. Remembering the written form is therefore more useful than trying to spell the word entirely from its sound.
How to Remember the Spelling Guarantee
A simple trick is to break the word into two parts:
GUARAN + TEE
That gives you:
GUARANTEE
You can also remember the phrase:
“I guarantee the TEE.”
The unusual memory phrase can help you remember that the word ends with -tee.
Another useful reminder is:
Guarantee has “guaran” before “tee.”
This helps distinguish it from the common misspelling guarentee.
Guarantee or Guarentee in American English
For American English writing, use guarantee.
The same standard spelling is also used in British English and other major varieties of English. Guarentee is generally treated as a misspelling rather than an alternative regional spelling.
Therefore, whether you are writing for a US audience, a British audience, or an international audience, guarantee is the safe and standard choice.
Why Do People Spell Guarantee as Guarentee?
The most common reason is pronunciation.
When people hear guarantee, they may focus on the final -tee sound and accidentally write the word as guarentee. The unusual sequence of letters in guarantee can also make the correct spelling harder to remember.
Another factor is visual familiarity. English contains many words with -ee endings, so guarentee may look plausible at first glance.
However, familiarity does not make the spelling correct. In standard English, the correct form is guarantee.
Guarantee vs. Guarentee: Quick Comparison
| Word | Correct? | Meaning |
|---|---|---|
| Guarantee | ✅ Yes | A promise or assurance; to promise or assure |
| Guarentee | ❌ No | Common misspelling of guarantee |
