Courses in English for special purposes, particularly in business, should be extended to native speakers of English. Problems of intercultural communication occur not only when people operate across linguistic boundaries but also when those people share a common language, particularly as new non-native varieties of English are becoming more commonly used. In countries such as Nigeria, Kenya, and India, English serves as a medium of intranational as well as international communication, but usually varies considerably from native North American or British models. Business people should seek to understand and use the linguistic forms dictated by non-native local circumstances. Analysis of learner language needs might include analysis of the types of interaction encountered in the non-native English situation, categorization of communicative problems, identification of systematic differences in the way native and non-native speakers use language, and establishing target communicative abilities to be learned by the native speaker. A syllabus for such a course should cover both productive and receptive language skills and both the structure and functions of language. Comparison of West African and Indian English provides examples. (MSE)
