Guarantee or Garantee: Which Spelling Is Correct?

The correct spelling is guarantee (ending in -ee). The alternate spelling garantee is an incorrect error with no standing in modern English dictionaries. The unusual gua start and the specific double-vowel ending are both remnants of the word’s Anglo-Norman French roots.

People frequently misspell the word as garantee because they are overapplying simple phonics—after all, the first syllable is pronounced like “gar” (/ˈɡær./), and other words meaning a safeguard use an -a- structure, like warranty or guard. However, English relies heavily on etymology for spelling. To maintain proper standard English, always spell it G-U-A-R-A-N-T-E-E.

Why Is “Guarantee” Spelled with a “UAA”?

The unusual gua combination comes down to language history:

1. The Norman French Influence

English borrowed guarantee from the Anglo-Norman word garantie (which in turn comes from the Germanic root war- meaning “to defend” or “to guard”). The Norman French added a silent u to words that originally started with a hard g (such as guard, guitar, and guise). English kept this silent u to honor the original French root.

2. Confused by “Warranty” and “Guard”

We are often misled by two closely related words that use a simple a:

• Gard: Pronounced with an /ɑː/ sound (GAHRD).
• Warranty: Pronounced with an /ær/ sound (WAIR-un-tee).

It feels logical to assume garantee follows the same vowel pattern. However, the silent u in guarantee serves only to look French, not to change the sound.

Proven Memory Tricks (Mnemonic Devices)

Use these quick mental associations to always get the vowel sequence right:

• “You and I (U and I) make a GUarantee.”Picture yourself and a business partner signing a contract. The first two vowels must be U and then I. If you write g-a-r-a-n-t-e-e, you have lost both of you! (GUAArantee).
• “The G.U.A. has a Warranty.”Connect the first three letters G.U.A. with the structure of WArranty.
