The correct use of the subjunctive forms in German is a challenging yet highly interesting topic in DaF (German as a Foreign Language) instruction. With the subjunctive II, we perfectly play the keyboard of politeness – whether in the form of polite questions or requests, as well as advice or suggestions. We also express unreal wishes or conditions using the subjunctive II. The subjunctive I, or indirect speech, is quite significant! Rarely used in everyday life, this mood is firmly anchored in journalistic texts and styles. This workbook intensively trains both the formation of forms and their content application through varied exercises. The material also prepares students for exams such as the Zertifikat Deutsch telc and the Goethe-/ÖSD-Zertifikat Deutsch.
