The author addresses the book to those who would like to study a foreign language on their own. Kato Lomb is convinced that dividing people into those who have and do not have "special language abilities" is wrong. It gives useful recommendations to language learners: how to make it easier to memorize new words, increase vocabulary, and master the correct pronunciation. In these councils, Kato Lomb relies on his own experience, invariably emphasizes this and indicates that he does not at all deny traditional teaching methods. The book, written in a living language in the manner of conversation (with changes and additions made by the author for the Russian edition), will be read with interest by everyone who is interested in learning foreign languages, as well as professionals - translators, teachers. This book is based on his own experience of learning 16 languages ​ ​ and working as a translator.
