Another \An*oth"er\, pron. & a. [An a, one + other.]
   1. One more, in addition to a former number; a second or
      additional one, similar in likeness or in effect.

            Another yet! -- a seventh! I 'll see no more.
                                                  --Shak.

            Would serve to scale another Hero's tower. --Shak.

   2. Not the same; different.

            He winks, and turns his lips another way. --Shak.

   3. Any or some; any different person, indefinitely; any one
      else; some one else.

            Let another man praise thee, and not thine own
            mouth.                                --Prov. xxvii.
                                                  2.

            While I am coming, another steppeth down before me.
                                                  --John v. 7.

   Note: As a pronoun another may have a possessive another's,
         pl. others, poss. pl. other'. It is much used in
         opposition to one; as, one went one way, another
         another. It is also used with one, in a reciprocal
         sense; as, ``love one another,'' that is, let each love
         the other or others. ``These two imparadised in one
         another's arms.'' --Milton.
