Away with English mistakes. The use of a foreign language inevitably leads to errors, but identifying one's own mistakes and those of others can be a challenge. Using texts with typical errors made by German-speaking learners, students, trainees, and teachers can practice recognizing and improving their own issues as well as the mistakes of their students. This includes varied learning and practice phases. Additionally, the concept of correctness in English is addressed, and reference works, websites, and corpora are recommended. The target norm is Standard British English, taking into account Standard American English.
