Ideogram \I*de"o*gram\, n. [Ideo- + -gram; cf. F. id['e]ograme.]
   1. An original, pictorial element of writing; a kind of
      hieroglyph expressing no sound, but only an idea.

            Ideograms may be defined to be pictures intended to
            represent either things or thoughts.  --I. Taylor
                                                  (The
                                                  Alphabet).

            You might even have a history without language
            written or spoken, by means of ideograms and
            gesture.                              --J. Peile.

   2. A symbol used for convenience, or for abbreviation; as, 1,
      2, 3, +, -, ?, $, ?, etc.

   3. A phonetic symbol; a letter.
