The present volume is a collection of 10 papers dealing with the subject of language change in German from a language teaching perspective. The contributions come from linguists and experienced professionals involved in teacher education and offer a rich variety of stimulating ideas and practical suggestions for the language classroom. The underlying concept of language change is a broad one, ranging from lexis, grammar and orthography to text, discourse and varieties. All contributions give a brief overview of the theoretical background followed by sections containing teaching materials for classroom use (i.e. texts, examples, exercises).
