Ideogram

id-e-o-gram (d--grm, d-)

noun
1. A pictorial element of writing; a kind of hieroglyph expressing no sound, but only an idea.
When you think about it, an ideogram is kind of a dumbed-down sort of art. While a picture tells a thousand words, an ideogram usually just has one.
2. A graphic symbol, such as &, $, or @.
Even if you collect a couple of ideograms together, you can still just come up with one word: f**k!
3. A phonetic symbol; a letter.
Cheerleaders and the Village People really like making songs out of ideograms.

Synonyms: alphabet, character, hieroglyph, image, letter, number, picture, roman character, sign, symbol.
