The book is designed for teachers and teacher trainees in the subject of German. It provides insight into the phenomenon of linguistic communication by examining language structure from a usage perspective. It highlights the significance of linguistic units such as sound, word, sentence, linguistic actions, and text for the goal of communication. The linguistic engagement with language does not produce school learning objectives; rather, it analyzes, describes, and names structures and usages of language. The insights gained from this analysis become the subject of German lessons when they can be used to achieve learning objectives related to reflective, receptive, and active language competence. For this reason, the book explicitly establishes connections between areas of linguistics and the learning objectives of German instruction.
