Investigating English provides a framework for the study of English Language. It is aimed at South African tertiary students and encompasses a year’s course. Basing the book on the premise that language is a complex system of signs for human communication, both aural and written. Glenda Heinemann explores the nature of language, considering such issues as the inseparable link between form and meaning, the relationship between language and thought, and how words determine the way we conceptualise the world and relate to other people. Investigating English incorporates some theoretical elements, but it relates closely to language use in the real world. Controversial issues such as accent and what constitutes correct pronunciation are discussed. How human beings acquire their primary language and later learn additional languages are areas covered. The topics dealt with in the different chapters prepare students for investigating an aspect of language that interests them particularly. An independent language investigation on a topic of their choice serves as the culmination of the year’s study. This project aims to promote independent thinking and initiative and to encourage the application of theory. It also develops research skills and the ability to write a cohesive report using appropriately academic language. Investigating English offers a logically structured approach to the study of language, and particularly English for South African students. It will be invaluable to those intending to become teachers or any other kind of language practitioner. Investigating English supplies an important need for all concerned with effective communication in English. It also encourages a broadminded attitude of understanding and tolerance of the diversity intrinsic to our South African linguistic context.
