A warranty is (1) a guarantee given by a company to a purchaser stating that a product will meet certain requirements during a given time, (2) official authorization, and (3) justification for a course of action. The word also has some legal uses that most of us will never have to use. A warrantee is someone to whom a warranty is given.
