In countries like Pakistan, with people of various cultures live, the languages of each part of the country also differ. English can be the only link as people in each place will not be able to learn all the other languages to communicate with the people. English bridges this gap and connects the people. When a person travels to another part of the world either for the sake of business or even as a tourist, the languages may differ. In these conditions, English is the language that helps people to deal with the situation. It is like a universal language.
The presence of English as a universal language assumes importance in the fact that more and more people leave their countries not only for the sake of business and pleasure, but also for studying. Education has increased the role of English. People who go to another country to study can only have English as their medium of study. This is because the individual will not be able to learn a subject in the local language of the country. This again reinforces the fact that the English language is very important.
All correspondences between offices in different countries and also between political leaders of various countries are in English. This linking factor also tells of the importance of the English language. In spite of the growth of the Internet in various languages, English is the mainstay of the Internet users. This is the language in which most of the information and websites are available. It is very difficult to translate each and every relevant webpage into the language of various countries. With Internet becoming very important in education, English language is bound to grow. Thus the importance of English as a language is emphasized.
The future of English as a language is very secure. The day is not far when this language will become the single language of the world like we have a single currency.
