Paragraph \Par"a*graph\, n. [F. paragraphe, LL. paragraphus, fr.
   Gr. para`grafos (sc. grammh`) a line or stroke drawn in the
   margin, fr. paragra`fein to write beside; para` beside +
   gra`fein to write. See {Para-}, and {Graphic}, and cf.
   {Paraph}.]
   1. Originally, a marginal mark or note, set in the margin to
      call attention to something in the text, e. g., a change
      of subject; now, the character [para], commonly used in
      the text as a reference mark to a footnote, or to indicate
      the place of a division into sections.

   Note: This character is merely a modification of a capital P
         (the initial of the word paragraph), the letter being
         reversed, and the black part made white and the white
         part black for the sake of distinctiveness.

   2. A distinct part of a discourse or writing; any section or
      subdivision of a writing or chapter which relates to a
      particular point, whether consisting of one or many
      sentences. The division is sometimes noted by the mark ?,
      but usually, by beginning the first sentence of the
      paragraph on a new line and at more than the usual
      distance from the margin.

   3. A brief composition complete in one typographical section
      or paragraph; an item, remark, or quotation comprised in a
      few lines forming one paragraph; as, a column of news
      paragraphs; an editorial paragraph.

Paragraph \Par"a*graph\, v. t. [imp. & p. p. {Paragraphed}; p.
   pr. & vb. n. {Paragraphing}.]
   1. To divide into paragraphs; to mark with the character
      [para].

   2. To express in the compass of a paragraph; as, to paragraph
      an article.

   3. To mention in a paragraph or paragraphs
