Mute \Mute\, a. [L. mutus; cf. Gr. my`ein to shut, Skr. m[=u]ta
   bound, m[=u]ka dumb: cf. OE. muet, fr. F. muet, a dim. of OF.
   mu, L. mutus.]
   1. Not speaking; uttering no sound; silent.
      [1913 Webster]

            All the heavenly choir stood mute,
            And silence was in heaven.            --Milton.
      [1913 Webster]

   Note: In law a prisoner is said to stand mute, when, upon
         being arranged, he makes no answer, or does not plead
         directly, or will not put himself on trial.
         [1913 Webster]

   2. Incapable of speaking; dumb. --Dryden.
      [1913 Webster]

   3. Not uttered; unpronounced; silent; also, produced by
      complete closure of the mouth organs which interrupt the
      passage of breath; -- said of certain letters. See 5th
      {Mute}, 2.
      [1913 Webster]

   4. Not giving a ringing sound when struck; -- said of a
      metal.
      [1913 Webster]

   {Mute swan} (Zool.), a European wild white swan ({Cygnus
      olor} syn. {Cygnus gibbus}), which produces no loud notes,
      in distinction from the {Trumpeter swan}.
      [1913 Webster]

   Syn: Silent; dumb; speechless.

   Usage: {Mute}, {Silent}, {Dumb}. One is silent who does not
          speak; one is dumb who can not, for want of the proper
          organs; as, a dumb beast, etc.; and hence,
          figuratively, we speak of a person as struck dumb with
          astonishment, etc. One is mute who is held back from
          speaking by some special cause; as, he was mute
          through fear; mute astonishment, etc. Such is the case
          with most of those who never speak from childhood;
          they are not ordinarily dumb, but mute because they
          are deaf, and therefore never learn to talk; and hence
          their more appropriate name is deaf-mutes.
          [1913 Webster]

                They spake not a word;
                But, like dumb statues, or breathing stones,
                Gazed each on other.              --Shak.
          [1913 Webster]

                All sat mute,
                Pondering the danger with deep thoughts.
                                                  --Milton.
          [1913 Webster]

Swan \Swan\ (sw[o^]n), n. [AS. swan; akin to D. zwaan, OHG.
   swan, G. schwan, Icel. svanr, Sw. svan, Dan. svane; and
   perhaps to E. sound something audible.]
   1. (Zool.) Any one of numerous species of large aquatic birds
      belonging to {Cygnus}, {Olor}, and allied genera of the
      subfamily {Cygninae}. They have a large and strong beak
      and a long neck, and are noted for their graceful
      movements when swimming. Most of the northern species are
      white. In literature the swan was fabled to sing a
      melodious song, especially at the time of its death.
      [1913 Webster]

   Note: The European white, or mute, swan ({Cygnus gibbus}),
         which is most commonly domesticated, bends its neck in
         an S-shaped curve. The whistling, or trumpeting, swans
         of the genus {Olor} do not bend the neck in an S-shaped
         curve, and are noted for their loud and sonorous cry,
         due to complex convolutions of the windpipe. To this
         genus belong the European whooper, or whistling swan
         ({Olor cygnus}), the American whistling swan ({Olor
         Columbianus}), and the trumpeter swan ({Olor
         buccinator}). The Australian black swan ({Chenopis
         atrata}) is dull black with white on the wings, and has
         the bill carmine, crossed with a white band. It is a
         very graceful species and is often domesticated. The
         South American black-necked swan ({Sthenelides
         melancorypha}) is a very beautiful and graceful
         species, entirely white, except the head and neck,
         which are dark velvety seal-brown. Its bill has a
         double bright rose-colored knob.
         [1913 Webster]

   2. Fig.: An appellation for a sweet singer, or a poet noted
      for grace and melody; as Shakespeare is called the swan of
      Avon.
      [1913 Webster]

   3. (Astron.) The constellation Cygnus.
      [1913 Webster]

   {Swan goose} (Zool.), a bird of India ({Cygnopsis cygnoides})
      resembling both the swan and the goose.

   {Swan shot}, a large size of shot used in fowling.
      [1913 Webster]
