I regularly teach courses in French and Italian linguistics (introductions, seminars, lectures, research seminars etc.). The list of courses currently taught is available on C@mpus.
Direct link for this semester: C@mpus courses Achim Stein
For most courses I provide materials either on this website or on the ILIAS platform (access restricted to university members).
I also wrote an introductory textbook for German students of French linguistics (Einführung in die französische Sprachwissenschaft).
