The classification of scripts and writing systems can be difficult. Some relationships and derivations are well-documented and accepted, but others are less clear. Many scripts also seem to have no particular relationship to any other script, other than hints of influence.

At the risk of over-simplification, ScriptSource uses a region-oriented family structure, where scripts are grouped mainly by where they were developed. Some consideration is also given to obvious similarities - Brahmic origin, writing direction, and others.

We would like to use a more robust and valid classification system in the future, and are very open to your suggestions.

African Scripts of indigenous African origin and heritage. Some have been influenced by Arabic writing, but most are unique inventions with interesting histories. Ethiopic, Tifinagh, Vai
American Scripts invented in the Americas and Caribbean, mostly for Native American languages. Cherokee, Unified Canadian Aboriginal Syllabics, Mayan Hieroglyphs
