This workbook for students of German (levels A2, B1 and beyond) explains the rules for adjective endings in an easy to understand, not too academic way. In a step-by-step approach, each new rule is accompanied by numerous exercises. In addition to adjective endings, the book gives a concise overview of "der-words" and "ein-words" and their declension, of the grammatical cases in German and their usage, and provides a list of the most important prepositions and the cases that they require. A short dictionary lists all nouns and verbs (with grammatical explanations) used in the exercises. The student can find an Answer Key for all exercises at the end of the book. The author, Ulrich Becker, is an experienced German language teacher (25+ years) and translator, an author of prose, poetry, and essays in German and other languages, and a recipient of the Humboldt Award (Humboldt University of Berlin).
