The workbook is aimed at learners who already have a basic knowledge of the Russian language and wish to expand it independently or in class. The book highlights the similarities and differences between German and Russian grammar, supplemented by grammatical comments. In particular, it addresses topics in phonetics, morphology, and syntax, as well as specific semantic groups of vocabulary that pose particular challenges for learners, such as the use of cases with and without prepositions and the use of verbal aspects. The exercises are organized by difficulty level. To facilitate the practical application of the material, many communicative exercises are designed to be practical and take into account the latest experiences in Russian language teaching. The explanations and exercises are complemented by numerous overview and comparison tables, as well as an answer key for the exercises.
