Various definitions of the term
world language have been proposed; there is no general consensus about which one is best. A definition proffered by Congolese linguist
Salikoko Mufwene is "languages spoken as vernaculars or as lingua francas outside their homelands and by populations other than those ethnically or nationally associated with them". Linguist
Mohamed Benrabah equates the term
world language with what Dutch
sociologist Abram de Swaan refers to as "supercentral languages" in his
global language system. Spanish sociolinguist
Clare Mar-Molinero proposes a series of tests that a language needs to pass, relating to demographics, attitudes towards the language, and political, legal, economic, scientific, technological, academic, educational, and cultural domains. German sociolinguist says that what determines whether something is a world language is its "global function", which is to say its use for global communication, in particular between people who do not share it as a native language and with use as a
lingua franca—i.e. in communication where it is not the native language of
any of the participants—carrying the most weight. == Possible examples ==
