World language
A world language (sometimes called a global language: 101 or, rarely, an international language) is a language that is geographically widespread and makes it possible for members of different language communities to communicate. The term may also be used to refer to constructed international auxiliary languages.
English is the foremost world language and, by some accounts, the only one. Other languages that can be considered world languages include Arabic, French, Russian, and Spanish, although there is no clear academic consensus on the subject. Some writers consider Latin to have formerly been a world language.
