of different contexts. The goal of this book is to help qualify teachers and students for this task. The book offers a unified description of vocabulary, grammar, pronunciation and varieties of English. The study of these four aspects of the language provides students with a broad understanding of language structure, which is a prerequisite for giving systematic and effective language instruction and enabling learners to make good choices. When the students learn about the fundamental components and systems in English, they will also develop an awareness of how other languages are constructed. This will help them use the linguistic diversity of many classrooms as a resource. This edition is a revision in accordance with the renewed national curriculum, LK20. It includes links to audio material, digital exercises and reflective tasks.
