Worldlang
A worldlang is a type of international auxiliary language (or auxlang) that derives its roots, phonology, and possibly grammar from different language families around the world, typically including several most widely spoken languages of the world.
History
Worldlangs are meant to be globally neutral. Traditional auxlangs tend to be Eurocentric as they favor the Western culture and languages: Otto Jespersen admitted, "But I cannot object to my formula [the greatest facility to the greatest number] being taken to refer only to Europeans and those inhabitants of the other continents who are either of European extraction or whose culture is based on European civilization."
Global neutrality was sometimes a claim of a-priori systems, but seldom of a-posteriori ones. Yet there are instances of the worldlang viewpoint in the twentieth century:
"And then, these languages are not international after all. A really international language ought to be as acceptable to speakers of Arabic, Chinese or Japanese as to a European."
