  Al·lit·er·a·tion n.  The repetition of the same letter at the beginning of two or more words immediately succeeding each other, or at short intervals; as in the following lines: -
  Behemoth, biggest born of earth, upheaved
  His vastness.   --Milton.
     Fly o'er waste fens and windy fields.   --Tennyson.
  Note: ☞ The recurrence of the same letter in accented parts of words is also called alliteration. Anglo-Saxon poetry is characterized by alliterative meter of this sort. Later poets also employed it.
  In a somer seson whan soft was the sonne,
  I shope me in shroudes as I a shepe were.   --P. Plowman.
