ASL is sometimes called ideographic, like Chinese writing.
Both ASL signs and ideographs are visible symbols. But, beyond this,
the similarity ends. Ideographs are written symbols that represent spoken
words. Historically derived from picture-writing, ideograms are not in
themselves recognizable symbols. The original forms - pictures, icons
- from which they evolved have been changed to suit the writers' needs.
After years of applying certain writing conventions, the forms of the
ideograms have become stylized and arbitrary. For example, in early Chinese
writing, the pictograph for sun was:
In present-day Chinese writing the ideogram for sun is
totally arbitrary:
The symbols of American Sign Language
are visible representations of concepts. They represent neither spoken
nor written words, thus making
it meaningless to refer to ASL as ideographic.
