In linguistics, a world language (sometimes global language,[1]: 101 rarely international language[2][3]) 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, and by some accounts the only, world language. Other possible world languages include Arabic, French, Russian, and Spanish, although there is no clear academic consensus on the subject. Some authors consider Latin to have formerly been a world language.
'international language' or 'world language' [...] The following languages of wider communication, that may be used as first or as second or foreign languages, are generally recognised: English, German, French, Spanish, Portuguese, Dutch, Arabic, Russian and Chinese.
