Over time there have been countless writing systems, which can be more or less categorized according to various properties.

The writing systems are used to express in written form one or more languages, dialects, etc., each of which can also be categorized according to a different set of properties (grammatical type, etc.)

I wonder if there is any sort of correlation among the historical use of certain categories of writing systems with certain categories of languages.

Anyone have any information or speculation?
