guarantee

guarantee: [17] Guarantee is essentially the same word as warrant, which is of Germanic origin (Germanic initial w- became g(u)- in the Romance languages). It was probably borrowed into English from the Spanish form garante (this is suggested by early spellings garanté and garante in English), and later changed to guarantee through confusion with guaranty [16] (itself originally a variant of warranty).
=> warrant

guarantee (n.)

For form evolution, see gu-. Sense of the "pledge" itself (which is properly a guaranty) developed 18c.
