Etymology: "Warranter" is about as plain as English word-building gets: it is the noun "warrant" with the agent suffix "-er" attached, so it names someone who warrants, that is, a person who gives a guarantee. The suffix "-er" has been used this way since Old English, turning verbs and nouns into names for the doers of an action, as in "teacher" or "lender." The base word carries more of the interest. "Warrant" came into English from Old French "warant," which meant a guarantee or a protection, and it is closely related to "guarantee" itself, the two being doublets that entered English by different routes. Over time "warrant" took on senses of authority, such as a legal order to arrest someone, and the older sense of a pledge or assurance remained beside them.

Synonyms: guarantor, surety
