How to Spell Guarantee (Common Mistakes)

  • 7 min read

Most Important: The Correct Spelling

✅ Correct
guarantee (ends with -tee)
❌ Wrong
guarentee, garantee, gurantee, guaranttee, guarantee (missing the second “e” at the end)

Also worth knowing: guaranty is a real spelling, but it’s not the everyday default. It often shows up in legal or financial language.

The word guarantee looks simple until your fingers start guessing. The standard spelling is guarantee: it has an a after gu and finishes with -tee. Most mistakes happen when people hear the ending as “tee” and accidentally type -tee without the second e at the end.

  • Main Form: guarantee
  • Common Mix-Up: guarentee
  • Variant: guaranty

What “Guarantee” Means In Modern English

Guarantee works as both a noun and a verb. As a noun, it’s an assurance or promise. As a verb, it means to promise something will happen or be true. Many dictionaries also show the stress on the last part (that -tee ending), which is one reason the spelling sticks out in your head once you notice it. ✅Source

Noun Uses

A guarantee can be a written or spoken promise—like a store policy, a service promise, or a general assurance.

Example “The repair comes with a guarantee.”

Verb Uses

To guarantee something is to promise it will happen or be true, often with a clear commitment behind it.

Example “They guarantee a response within 24 hours.”


Why Misspellings Happen

Guarantee is a classic “looks odd, sounds normal” word. The spelling has a few trap points: extra vowels, a soft-looking middle, and that -tee ending that people try to “simplify” by accident. Once you know what usually breaks, the common errors make perfect sense.

  1. Vowel swapping: people flip a and e and land on guarentee.
  2. Ending shortcut: the sound “tee” makes some writers stop at one e at the end.
  3. Middle blur: the “aran” chunk is easy to mistype as uran or aran with a missing vowel.
  4. Extra letters: sometimes people “over-fix” and add a letter, creating guaranttee.

One small detail that matters: the word ends with -tee, so the final spelling has two e’s in a row at the end: guarantee.

Common Mistakes

These are the misspellings that show up again and again. Each one is close to guarantee, which is exactly why it slips past the eye. Watch the vowels and the double-e ending, and most errors disappear.

  • ❌ Wrong guarentee✅ Correct guarantee (a and e are in the right places)
  • ❌ Wrong garantee✅ Correct guarantee (missing u after g)
  • ❌ Wrong gurantee✅ Correct guarantee (missing the a after gu)
  • ❌ Wrong guaranttee✅ Correct guarantee (extra t)
  • ❌ Wrong guarante✅ Correct guarantee (missing the final e)
Typical Typos for “Guarantee” (What Changed and What You Wanted)
Misspelling What Usually Happened Correct Form Example (Corrected)
guarentee Vowels flipped in the middle guarantee “We offer a one-year guarantee on parts.”
garantee Missing u after g guarantee “The plan includes a guarantee of support.”
gurantee Skipped the a after gu guarantee “They guarantee delivery by Friday.”
guarante Stopped early at the end guarantee “The service comes with a guarantee.”

Guarantee vs. Guaranty and Why Both Exist

Guarantee and guaranty are both standard spellings in English, but they don’t feel equally common in everyday writing. You’ll usually see guarantee in general contexts, while guaranty often appears in more formal or contract-heavy language. Some references also record guaranty as an older form, with word-history notes attached to it. ✅Source

Plain-English Take

If you mean the everyday promise or assurance, guarantee is the spelling most readers expect. Guaranty can still be correct, but it may read as more legal or institutional.

When “Guaranty” Shows Up In Legal Writing

In legal contexts, a guaranty is commonly explained as an undertaking or promise tied to another person’s obligation—often around a debt or loan. That legal sense is one reason the spelling guaranty keeps showing up in contracts and finance documents, even when everyday writing sticks with guarantee. ✅Source
