The book offers a detailed account of English influence on German based on a large scale corpus analysis of the newsmagazine ‘Der Spiegel’. The study is structured into three parts covering fundamental questions and as of yet unsolved and disputed issues in the domain of anglicism research and language contact. Part 1 discusses the terminological uncertainty in the field, puts forward a model of the influence of English on German, and proposes a principled classification of the term anglicism. Part 2 portrays the numerical impact of anglicisms in an extensive corpus and draws general conclusions about the overall quantitative influence of English on German. Part 3 conclusively investigates the integration of anglicisms in German across the various lexical and syntactic paradigms. Particular focus is attributed to the salient morphological features of gender, plural, genitive case, and to verbal and adjectival inflection. Furthermore, word formational processes are substantively analyzed including compounding, derivation, and peripheral types of word formation. A functional classification of written codeswitching concludes part 3, and the book closes with a brief outlook on future challenges of anglicism research. In its breadth and detailed manner of analysis, the study sets the current standards of research in the field.
