English as a second language (ESL) is the use or study of English by speakers with different native languages.
English as a language has great reach and influence; it is taught all over the world. In English-speaking countries, English language teaching has evolved in two broad directions: instruction for people who intend to live there, and instruction for those who do not. These divisions have grown firmer as the instructors of these two "industries" have used different terminology, followed distinct training qualifications, formed separate professional associations, and so on. Crucially, these two arms have very different funding structures, public in the former and private in the latter, and to some extent this influences the way schools are established and classes are held. Matters are further complicated by the fact that the United States and the United Kingdom, both major engines of the language, describe these categories in different terms.

English is very important nowadays in our live. English may be a foreigner language but at the same time it is international because it is the world’s most frequently used language in business, education, literature, politics, science, technology, and communication. Thomas A. Case said “The English language is important for international communication. In Asia, the spread of the British Empire in the first part of the last century and the influence of the U.S. global military and economic policies in the second half of the century have established English as the international lingua franca of government and commerce.” (Thomas A. Case p.144)
