Guarantee is the correct spelling, while guarentee is a common misspelling that should not be used in standard English.
The confusion happens because the word is pronounced in a way that can make the middle vowel sound unclear, causing writers to spell it as they hear it.
Guarantee means a promise, assurance, or firm commitment that something will happen or meet a certain standard.
In this article, you will learn the difference between guarantee and guarentee, discover the word’s origin, understand British and American usage, see common mistakes, and learn how to use guarantee correctly in everyday writing.
You will also get examples, spelling tips, FAQs, and usage guidance.
Quick Answer
Guarantee is the correct spelling.
Guarentee is incorrect and should not be used in formal or professional English.
The word guarantee can be used as both a noun and a verb.
As a noun, it means a promise or assurance:
- The phone comes with a two-year guarantee.
- The company gave us a written guarantee.
- There is no guarantee that the plan will work.
As a verb, it means to promise or assure:
- We guarantee excellent service.
- This treatment does not guarantee success.
- The seller guarantees that the product is genuine.
The spelling guarentee is simply a misspelling. It does not represent a separate word or an alternative British or American spelling.
The Origin of Guarantee vs Guarentee
The correct spelling guarantee has a long history and comes through French. It is related to words such as guarantor, guaranty, and warranty, all connected with the idea of giving security or assurance.
The spelling developed through forms related to French garant, meaning someone who provides security or assurance. English adopted the word and its spelling over time. The gua- beginning became part of the established English form.
This history explains why the spelling is not as simple as its pronunciation might suggest. English contains many words whose spelling reflects their history rather than exactly matching their modern pronunciation.
That is why writers sometimes produce forms such as:
- guarentee
- garantee
- garentee
- gurantee
- gaurantee
However, only guarantee is the standard spelling for the word discussed here. Modern spelling references consistently identify guarentee as incorrect.
A useful way to remember it is:
GUA + RAN + TEE = GUARANTEE
The ending is -tee, but the middle of the word is -ran-, not -reen-.
British English vs American English Spelling
There is no British-versus-American spelling difference between guarantee and guarentee.
Both British English and American English use:
guarantee
The misspelling guarentee is not an accepted American alternative. It is also not an accepted British alternative.
| English variety | Correct spelling | Incorrect spelling |
|---|---|---|
| British English | guarantee | guarentee |
| American English | guarantee | guarentee |
| Canadian English | guarantee | guarentee |
| Australian English | guarantee | guarentee |
| New Zealand English | guarantee | guarentee |
| International English | guarantee | guarentee |
For example:
British English:
The product has a five-year guarantee.
American English:
The product has a five-year guarantee.
The spelling remains unchanged.
This makes the choice easy: regardless of whether you are writing for readers in the United States, United Kingdom, Canada, Australia, or another English-speaking country, use guarantee.
Which Spelling Should You Use?
Use guarantee in every standard English context.
If you write for a US audience
Use guarantee in emails, websites, advertisements, contracts, schoolwork, and business documents.
Example:
We guarantee delivery within five business days.
If you write for a UK or Commonwealth audience
Use guarantee as well.
Example:
Your purchase comes with a two-year guarantee.
If you write for a global audience
Guarantee is the safest and universally recognized form.
You do not need to change the spelling based on the reader’s country.
The important point is that guarentee is not a regional spelling. It is simply an error.
Common Mistakes with Guarantee vs Guarentee

Guarantee vs Guarentee – Google Trends & Usage Data
People frequently search for spelling questions involving guarantee, especially when they are unsure about the order of the vowels.
Google Trends allows users to compare search terms and examine interest by location and time. Google also explains that ordinary searches do not automatically combine misspellings with correctly spelled terms; alternative spellings and misspellings can be compared separately when specifically included.

The correct spelling is widely used in:
- Business communication

Usage by country
There is no meaningful US-versus-UK spelling split for this word. English speakers in both regions use guarantee.
The difference is therefore not geographical. It is mainly a matter of correct spelling versus a common spelling error.
If you are writing online, using guarantee is important for credibility, especially on business pages, product pages, professional websites, and formal documents.
Easy Trick to Remember Guarantee
A simple memory trick is:
GUARANTEE has “TEE” at the end.
Break it into:
GUA + RAN + TEE
Think:
Guarantee = GUA + RAN + TEE
You can also connect it with guarantor:
guarantee → guarantor
Both begin with guar-.
So remember:
GUAR, not GUAR + EE in the middle.
Another quick check is to look at the first five letters:
GUARA
If you write GUARE, you have probably created the common misspelling guarentee.
