Business English is a part of English for specific purposes and can be considered a specialism within English language learning and teaching, or a variant of international English. Many non-native English speakers study the subject with the goal of doing business with English-speaking countries, or with companies located outside the English-speaking world but which nonetheless use English as a shared language or lingua franca. Much of the English communication that takes place within business circles all over the world occurs between non-native speakers. In cases such as these, the object of the exercise is efficient and effective communication. The strict rules of grammar are in such cases sometimes ignored, when, for example, a stressed negotiator’s only goal is to reach an agreement as quickly as possible.
