\War"rant*y\, n.; pl. {Warranties}. [OF. warantie, F.
garantie. See {Warrant}, n., and cf. {Guaranty}.]
1. (Anc. Law) A covenant real, whereby the grantor of an
   estate of freehold and his heirs were bound to warrant and
   defend the title, and, in case of eviction by title
   paramount, to yield other lands of equal value in
   recompense. This warranty has long singe become obsolete,
   and its place supplied by personal covenants for title.
   Among these is the covenant of warranty, which runs with
   the land, and is in the nature of a real covenant. --Kent.
2. (Modern Law) An engagement or undertaking, express or
   implied, that a certain fact regarding the subject of a
   contract is, or shall be, as it is expressly or impliedly
   declared or promised to be. In sales of goods by persons
   in possession, there is an implied warranty of title, but,
   as to the quality of goods, the rule of every sale is,
   Caveat emptor. --Chitty. Bouvier.
3. (Insurance Law) A stipulation or engagement by a party
   insured, that certain things, relating to the subject of
   insurance, or affecting the risk, exist, or shall exist,
   or have been done, or shall be done. These warranties,
   when express, should appear in the policy; but there are
   certain implied warranties. --Bouvier.
4. Justificatory mandate or precept; authority; warrant. [R.]
   --Shak.
         If they disobey precept, that is no excuse to us,
         nor gives us any warranty . . . to disobey likewise.
                                               --Kettlewe??.
5. Security; warrant; guaranty.
         The stamp was a warranty of the public. --Locke.
Syn: See {Guarantee}.
