Loyalty \Loy"al*ty\, n. [Cf. F. loyaut['e]. See {Loyal}, and cf.
   {Legality}.]
   The state or quality of being loyal; fidelity to a superior,
   or to duty, love, etc.

         He had such loyalty to the king as the law required.
                                                  --Clarendon.

         Not withstanding all the subtle bait With which those
         Amazons his love still craved, To his one love his
         loyalty he saved.                        --Spenser.

   Note: ``Loyalty . . . expresses, properly, that fidelity
         which one owes according to law, and does not
         necessarily include that attachment to the royal
         person, which, happily, we in England have been able
         further to throw into the word.'' --Trench.

   Syn: Allegiance; fealty. See {Allegiance}.
