This book is intended for those learning German. Mainly for beginners, although advanced experts may also find something useful in it. It is based on extensive experience in teaching and self-studying the language, which I have tried to summarize and present in the form of tips and recommendations regarding the main topics of German grammar and vocabulary. At the same time, I tried to do this in the most accessible and comfortable form and even make it as interesting as possible. This is not a textbook, or rather, not a classic textbook, but rather a short reference book or guide that will help you better understand and understand the German language. And I recommend this book in addition to those German textbooks that you are already studying.
