There is not a single people in the world whose language does not contain swear words. They are even compared to volcanic eruptions, bursting out from under the crust of social prohibitions. This book is dedicated to such an unusual lexical layer. I would like to understand why something that the same society prohibits persists in society. The object of study in the book is not all human speech activity, but mainly the means of expressing human emotions. And one of the most emotional means of expression is swear words. The book you are holding in your hands is based on the doctoral dissertation of its author, but he rewrote it so that it would be understandable even not to a specialist, but simply to a lover of Russian literature. Contains obscene language. The publishing design is preserved in PDF A4 format.
