A popular science book about the rules and patterns of the Russian language. Clearly and concisely about the most difficult cases.
Literacy today is important not only for those who work professionally with texts, — it is important for everyone who works with people. Is it necessary for you personally?
Yes, if you work with children. Yes, if you are a lawyer, doctor, or expert in any other consulting field and rely on serious clients. Yes, if you are involved in trade. Especially if your image (or your company's image) is connected with social networks and blogs.
This book will help you quickly memorize the simple rules of the Russian language and will always be at your fingertips, even in the most complicated cases (N and NN in different parts of speech, spelling of NE and NI, and so on).
