The book A lass! Mir léiere Lëtzebuergesch A2.1 is aimed at intermediate-level learners who want to learn the basics of the Luxembourgish language. The first four chapters cover four main topics: how to introduce yourself, talk about your hobbies and family, and how to communicate at school. At the same time, QR codes provide access to additional listening and exercises as well as the book's answer key, which allows for independent learning. Thanks to the many oral exercises, learning in pairs or in groups is also possible, with a view to practicing oral expression. This book is intended for anyone who wants to learn or improve their Luxembourgish.
