Etymology: "Guaranteer" is a plain formation: the noun "guarantee," a promise that something will be done or that a debt will be paid, with the agent suffix "-er" added to name the person who makes that promise. So a guaranteer is someone who stands behind another's word or obligation, the one who vouches for it. The base word "guarantee" has a more tangled past than its ending suggests. It came into English from the French "garantie," and it is closely related to "warranty," which entered English through a parallel French form. The two words are doublets, both descending from the same root, which is why "guarantee" and "warrant" share so much of their sense of assurance. Because "guaranteer" is built directly from "guarantee" in English, its meaning follows the base word's sense of pledged security rather than any independent history of its own. It is a useful, if less common, alternative to "guarantor," which carries the same meaning but comes through a Latin-derived legal route.
