Correct spelling, explanation: guarantee is the correct version of the word, despite the way it might look when checking the etymology. The word comes from French garant, but over time it underwent several visual changes, mostly caused by the pronunciation: u was added to soften the hard ga, while ee at the end is caused by the long i sound.

Definition of guarantee:
Noun
1. a promise or assurance of fulfilling certain expectations.
This certification is a guarantee of good value.
Verb
1. to promise or assure someone of fulfilling certain expectations.
I can guarantee you will be satisfied with this purchase.

Incorrect spelling, explanation: despite its etymology, garanty is not the correct version, as over time the word became properly anglicized and adapted to English spelling and pronunciation rules. There is no simple explanation why the word changed so much – but as of now, guarantee fits the English pronunciation much more.
