English as a global language

Because English is so widely spoken, it has often been referred to as a "world language", the lingua franca of the modern era, and while it is not an official language in most countries, it is currently the language most often taught as a foreign language. Some linguists believe that it is no longer the exclusive cultural property of "native English speakers", but is rather a language that is absorbing aspects of cultures worldwide as it continues to grow. It is, by international treaty, the official language for aerial and maritime communications. English is an official language of the United Nations and many other international organisations, including the International Olympic Committee.

English is the language most often studied as a foreign language in the European Union, by 89% of schoolchildren, ahead of French at 32%, while the perception of the usefulness of foreign languages amongst Europeans is 68% in favour of English ahead of 25% for French. Among some non-English-speaking EU countries, a large percentage of the adult population claims to be able to converse in English – in particular: 85% in Sweden, 83% in Denmark, 79% in the Netherlands, 66% in Luxembourg and over 50% in Finland, Slovenia, Austria, Belgium, and Germany.

Books, magazines, and newspapers written in English are available in many countries around the world, and English is the most commonly used language in the sciences with Science Citation Index reporting as early as 1997 that 95% of its articles were written in English, even though only half of them came from authors in English-speaking countries.

This increasing use of the English language globally has had a large impact on many other languages, leading to language shift and even language death, and to claims of linguistic imperialism. English itself is now open to language shift as multiple regional varieties feed back into the language as a whole.
