The English language is a living language.

Latin would be a good example of a dead language.

A dead language is one in which there is no current population using said language on a daily basis and so that language is considered to be impervious to the kind of changes that culture, society, technology and changing times can bring to a language that is still in use.

This is why the scientific and legal fields long ago decided to use Latin as the language for codified laws, theories, discoveries and basic nomenclature.

The "double negative" rule as applied to the English language, which is spoken currently in quite a few different countries and regions, each having developed their own curious usage, definitions and rules, is very likely outdated and is a remnant due to changing times and generations.

The double negative usage also may be quite differently used today depending upon which English speaking nation, which country, culture, etc. being discussed.
