The C-Grammar is a practice grammar designed for learners at the C1 and C2 levels of the Common European Framework of Reference for Languages. It is suitable both as supplementary material for courses and for individual study.

Grammatical phenomena are introduced in each section through illustrated examples and then practiced and repeated through progressively structured exercises. Additionally, each topic includes clearly organized tables of grammatical forms and neatly arranged notes and information on specific usage. The topics of the exercises are chosen to be entertaining and engaging, allowing learners to deepen their understanding of grammatical structures while also discovering new information. Vocabulary from everyday and professional life is learned simultaneously. Various exercise formats make the learning process diverse and therefore motivating.

A solution booklet is included with the book.
