What is a Global Language?
There is no official definition of “global” or “world” language, but it essentially refers to a language that is learned and spoken internationally, and is characterized not only by the number of its native and second language speakers, but also by its geographical distribution, and its use in international organizations and in diplomatic relations. A global language acts as a “lingua franca”, a common language that enables people from diverse backgrounds and ethnicities to communicate on a more or less equitable basis.
Historically, the essential factor for the establishment of a global language is that it is spoken by those who wield power. Latin was the lingua franca of its time, although it was only ever a minority language within the Roman Empire as a whole. Crucially, though, it was the language of the powerful leaders and administrators and of the Roman military - and, later, of the ecclesiastical power of the Roman Catholic Church - and this is what drove its rise to (arguably) global language status. Thus, language can be said to have no independent existence of its own, and a particular language only dominates when its speakers dominate (and, by extension, fails when the people who speak it fail).
The influence of any language is a combination of three main things: the number of countries using it as their first language or mother-tongue, the number of countries adopting it as their official language, and the number of countries teaching it as their foreign language of choice in schools. The intrinsic structural qualities of a language, the size of its vocabulary, the quality of its literature throughout history, and its association with great cultures or religions, are all important factors in the popularity of any language. But, at base, history shows us that a language becomes a global language mainly due to the political power of its native speakers, and the economic power with which it is able to maintain and expand its position.
What About The Future?
Although English currently appears to be in an unassailable position in the modern world, its future as a global language is not necessarily assured. In the Middle Ages, Latin seemed forever set as the language of education and culture, as did French in the 18th Century. But circumstances change, and there are several factors which might precipitate such a change once again.
There are two competing drives to take into account: the pressure for international intelligibility, and the pressure to preserve national identity. It is possible that a natural balance may be achieved between the two, but it should also be recognized that the historical loyalties of British ex-colonies have been largely replaced by pragmatic utilitarian reasoning.

A 2006 report by the British Council suggests that the number of people learning English is likely to continue to increase over the next 10-15 years, peaking at around 2 billion, after which a decline is predicted. Various attempts have been made to develop a simpler “controlled” English language suitable for international usage (e.g. Basic English, Plain English, Globish, International English, Special English, Essential World English, etc). Increasingly, the long-term future of English as a global language probably lies in the hands of Asia, and especially the huge populations of India and China.
Having said that, though, there may now be a critical mass of English speakers throughout the world which may make its continued growth impossible to stop or even slow. There are no comparable historical precedents on which to base predictions, but it well may be that the emergence of English as a global language is a unique, even an irreversible, event.
