[Fr. idéographique, from Gr. ἰδέα, idea, and γράφειν, to write.] Representing ideas; standing for and representing a notion or idea, without reference to the name given to it, as by means of figures, symbols, or hieroglyphics; thus, the digit 9 does not represent the word nine, but the idea itself of the number.
