After the EU expansion, Polish is becoming increasingly important in universities and the professional world. As the first Polish textbook, the one-volume "Jadnych granic! Polish from A to Z" covers levels A1 to B2 of the Common European Framework of Reference for Languages. In just four semesters, "Polish from A to Z" allows learners to acquire a comprehensive basic vocabulary and all grammatical phenomena necessary for understanding texts and producing written content. In 16 lessons, which lead to language proficiency at level B2 with a high progression, the newly introduced vocabulary is presented through dialogues and texts. Starting from lesson 7, authentic texts are used, providing a broad knowledge of Polish culture and geography. Grammatical phenomena are presented in a systematic manner.
