What are the positive and negative aspects of English as a global language? In our modern world we need to have a mean, which helps people to communicate with each other. This mean of communication is English language. In fields of business, academics, science, computing, education, transportation, politics and entertainment, English is already established as the de facto lingua franca. But there are positive and negative aspects of using English as a global language. The first positive aspect is that English give us possibility to carry on simultaneous dialogue not only between two cultures, but between different communities from all over the world. Historically English has a good business, political and academic vocabulary and it makes English convenient for communication, especially in these fields. In my opinion, English has very flexible structure, it easily creates new words and simply adjusts to changing of modern reality. There are negative aspects of using English as a global language. Linguists say that using English as a global language oversimlified its structure. If English is influenced by another languages, it will be Czenglish or Spanglish - the results from interaction between Czech and English or Spanish and English used by people who speak both languages orparts of both languages. Another risk is the weakening and eventually disappearance of some minority languages, because of dominance of American and English – in music, film, business, finance, information technology and the Internet. We can see, that modern world need a global language which is English and using English as a global language has the positive and negative aspects.
