"zonal auxiliary language"の定義と意味

What is a "zonal auxiliary language"?

A zonal auxiliary language is a language created to serve as a common means of communication across a specific geographic area, often among speakers of different native languages. It is designed to facilitate understanding and interaction, especially in regions with diverse linguistic backgrounds. Unlike a national language, which may be the official language of a country, a zonal auxiliary language aims to promote communication within a particular zone or region. These languages are often simplified and may borrow features from several local languages to ensure that they are accessible to a wide range of speakers.
