This textbook offers a communicative-oriented introduction to the Dari-Persian language of Afghanistan and aims to acquire a comprehensive basic knowledge. An introductory chapter is devoted to the Arabic-Persian script and the pronunciation of Dari-Persian. In forty further chapters, the learners are enabled to exchange ideas in representative communicative situations, initially on concrete, real-life topics and later on more abstract content. Numerous aspects of regional culture and history are also examined here. Vocabulary and grammar are taught step by step according to the communicative requirements. Important phrases that enable lively communication are provided as a means of expression. The solution part enables self-control of the exercises. Two glossaries summarize the vocabulary taught. Audio recordings are also available for many texts, dialogues and vocabulary lists. Video materials support learning to write and later help to acquire new words in sound and writing. The Dari-Persian textbook ranges from level A1 to B1 of the European Framework of Reference and is suitable for both teaching and self-study.
