| Notes: | guarantee is from Old French garant 'a warrant,' while warranty is from Old North French warantie, derived from warant 'a warrant.' Both garant and warant came from Frankish (the West Germanic language spoken in the 400s and 500s in the region of ancient Gaul that became France), represented by Old High German weren 'to confirm, warrant.' Guarantee is a general term for a representation regarding a good's quality and performance - and warranty is the legal term for the document; the person to whom it is issued is the warrantee with the issuer being the warrantor |
