The term "ideogram" is often used to describe symbols of writing systems such as Egyptian hieroglyphs, Sumerian cuneiform and Chinese characters. In the light of the modern understanding of Old Chinese phonology, researchers now believe that most of the characters originally classified as semantic compounds have an at least partially phonetic nature.[2] An example of ideograms is the collection of 50 signs developed in the 1970s by the American Institute of Graphic Arts at the request of the US Department of Transportation.[3] The system was initially used to mark airports and gradually became more widespread. Inspired by inaccurate early descriptions of Chinese and Japanese characters as ideograms, many Western thinkers have sought to design universal written languages, in which symbols denote concepts rather than words. ./cache/en-wikipedia-org-2871.html ./txt/en-wikipedia-org-2871.txt
