The earliest writing systems were not phonetic; the symbols used did not directly reflect the speech sounds of the language. Rather, the first writing was pictographic, consisting of simplified drawings of objects and animals. This limited system gradually began to include ideographic signs, which symbolized more abstract concepts relating to the original pictograph. For example, a pictograph of the sun might also come to mean “day” or “light.” Eventually, logographic signs were added. These were signs invented to symbolize words but no longer had a direct pictorial connection.
