The DaF Palette 4: Prepositions is a comprehensive textbook aimed at learners at levels C1 to C2. It is designed for both teenagers and adults and is excellent for self-learners as well as for use as supplementary material in language courses. The book aims to expand and systematize existing knowledge of prepositions. Through targeted exercises and study lists, it deepens the understanding of causal and modal prepositions. The structure of the book allows learners to gradually solidify their skills, with exercises increasing in difficulty. Additionally, the book includes interim tests and a final test for learning assessment to check progress. An answer key in the appendix facilitates independent learning and self-assessment.
