Late 17th century (in the sense 'guarantor'): perhaps from Spanish garante, corresponding to French garant (see warrant), later influenced by French garantie 'guaranty'.

  • A guarantee and a warranty (Middle English) are basically the same thing and go back to a common source. Warrant (Middle English) and warranty are earlier, coming from Norman French, showing the typically Norman ‘w’ variant of French garantie. Guarantee seems to have come from the Spanish equivalent and to have been influenced by the French form.
