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.): 1670s, "person that gives security," altered (perhaps via Spanish garante or confusion with legalese ending -ee), from earlier garrant "warrant that the title to a property is true" (early 15c.), from Old French garant "defender, protector; warranty; pledge; justifying evidence," from Germanic (see warrant (n.)). For form evolution, see gu-. Sense of the "pledge" itself (which is properly a guaranty) developed 18c.
guarantee (v.): 1791, "to be surety for," from guarantee (n.). Garanten in this sense is from early 15c. Related: Guaranteed; guaranteeing.
