The main aim of this book is to teach learners how to use Persian grammar in contexts. Language learners learn to use Persian language grammar through doing some tasks (e.g., agreement, disagreement, explanation, reasoning, comparison, etc.). As the mere memorization of the grammars does not guarantee that language learners can use them effectively, different tasks were provided so that they can use the grammars in different contexts.The book is most suitable for intermediate learners. The extensive glossary is also a great help. It is not a self-study book, however. A good instructor can make a big change. You will have very good progress both in Persian Grammar and Speaking.Learners need to complete a 40 hours Persian course prior to using this book. Very VERY HAPPY! Purchased by language teachers, and language Learners from Both US and Europe. THANK YOU.
