Etymology: "Warrantor" is a plain English formation: the noun "warrant" with the agent suffix "-or" attached, meaning one who gives a warrant. The suffix has a long ancestry. It descends from a Latin agent ending "-tor", which passed into Old French as "-eor" and then into Middle English as "-our", the same route that gave English words like "actor" and "author" their endings in some forms. English "-or" was then freely attached to native and borrowed roots to name the person performing an action. The base word is the more interesting half. "Warrant" is itself an English word with a French-influenced history, and it carries the sense of a guarantee or a legal authority. Adding "-or" to it produces a term for the party who stands behind that guarantee. Because "warrantor" is built directly from an English base and a productive suffix, it is a transparent formation rather than a borrowing, and its meaning follows straightforwardly from the parts.
